Mary and the Problem of Christian Unity

Mary appears in Scripture to be intimately and inseparably bound to her Son Jesus Christ. She was more than just the human flesh through which the Divine Word entered the world. She was united to Christ in body and soul. And Jesus was also bound to her as her child, her Lord and the source of her life. She was the source of his human life and he was the source of the divine life that filled her life. This intimate union between Jesus and Mary is the foundation and basis of our hope that Christians can be unified. Unity is not an unfulfilled wish or an amorphous hope. Unity has both material and form, both substance and shape. Unity looks like a man and indeed is a man. Jesus alone is our unity, but Jesus is never alone. He is always with his mother.

The same Jesus that came from Mary’s womb also founded a church and promised that the gates of hell would not be able to withstand the onslaught of the kingdom of God (Mt. 18:18). The same Jesus that nursed at Mary’s breast prayed for the unity of his followers in the garden on the night before his death (Jn. 17). In this article we want to explore why Christians are not unified and how Scripture points us to a solution. We will see that unity among Christians cannot be achieved with means of our own contriving. Only by drawing deeply from the wellspring of Christ’s own person can we hope to find the unity that Christ desires.

Christians are divided and Christ cannot be pleased. Our Lord prayed for the unity of his followers on the last night of his earthly life, a fact that shows how deeply he cares about the unity of his disciples (Jn. 17:20ff). Why does Christ care if his people are one? The Old Testament promised the unity of God’s people when the Messiah came.

That alone suggests that Jesus’ ministry on earth had to fulfill one of the most important promises of the ancient Scriptures. If the people of God were not one, then Christ would have failed in his mission of salvation. Since there is only one Savior, there should be only one people who are saved. But why are Christians not one? If that was Jesus’ intention, what went wrong?

In the college town where I live, Christian students recently had a “Jesus Night.” This event was billed as an attempt for all the Christian groups on campus to lay down their differences and come together to worship Jesus. “Leave our differences at the door” was the cry. Apparently, the event was a big success because it met a felt need among the participants, the need to express our love for one another in Christ. This Jesus Nightarose from a God-given sentiment, that of being one in Christ. But it also illustrates one of the thorniest problems facing Christians who seek to be unified in Christ. Doctrinal differences have divided Christians for centuries. The desire to be one and the need to believe the truth that Christ taught are both genuine inspirations from the Holy Spirit. But how does one balance these two important truths? My own personal struggles in this matter illustrate the problem that is deep and wide among Christians.

The Dilemma of Truth Versus Unity: A Personal Struggle

In May of 1977, I graduated from Westminster Theological Seminary in Philadelphia, Pennsylvania. I had spent three solid years in theological study that was intended to prepare me for the Presbyterian ministry. One of my professors was Rev. Edmund Clowney, the president of the seminary, who taught a class on the doctrine of the Church (ecclesiology). Professor Clowney spent a good amount of time addressing an urgent question he felt was being neglected by most evangelical Christians. From the Scriptures, Mr. Clowney urged on us the importance of the unity of the Church. He saw quite clearly how fragmented evangelical Christians were and how much this situation contradicted our Lord’s desire in John Chapter 17. His teaching sparked within me a desire for something I had seen in the Scriptures myself. During my college years, I had already been impressed with how Paul exhorted his readers in Corinth to be unified in doctrine and love (I Cor. 1:10ff). By the end of seminary, I had already concluded on the basis of the New Testament that many different denominations were not the intention of Jesus Christ nor of his apostles. But I was at a loss to know what to do about the problem of divisions among Christians.

In 1978, I preached a sermon from John Chapter 17 at an ordination service of a fellow Presbyterian minister. I urged the congregation that day to seek unity among themselves. As I reflected on the intensity of our Lord’s prayer recorded by John, I realized that Jesus would not be pleased with Christians who divided themselves from one another. I even went so far as to say that if the Roman Catholic Church ever came back to the Gospel of Jesus Christ, we must go back to it. At that time, I sincerely believed that the Catholic Church was not teaching the real Gospel.

The problem of disunity among Christians continued to haunt me for years. In 1988, I began teaching at a Protestant seminary. Although I was teaching Biblical Studies, I spent a lot of time reading Church history, especially Protestant church history. I was working on a book on the history of science and religion in Protestant lands during the time of the Reformation. I had studied Church history in seminary, but this time my reading revealed facts that astounded me. I discovered that within one hundred fifty years after Martin Luther first posted his ninety-five theses on the Wittenberg church door, the Protestant movement was hopelessly fragmented. In England alone, there were literally hundreds of groups who claimed their interpretations of the Bible and Christian doctrines were the correct ones. Some Protestant groups, especially the more independent ones, developed the idea of the spiritual nature of the Church.

They claimed that the institutional church was relatively unimportant and that the only necessary thing was for an individual believer to have a relationship with Jesus Christ. No Christian body in history has ever denied that a living relationship with Jesus Christ is necessary for salvation. The innovation of certain modern forms of Protestantism was that this was all that was important and that the institutional church must take a back seat. This same belief echoes down to our day: “It doesn’t matter what church you belong to as long as you know Jesus.” Whether they meant it or not, that was the message conveyed by the college students who held their Jesus Night.

As I studied my way through four hundred years of Protestant history, a pattern began to emerge that can be illustrated from twentieth-century Protestantism. In the early decades of this century, there arose the problem of liberalism or modernism, as some called it. Classic Protestant Liberalism said in essence that it was not important whether one believed in the historic doctrines of the Christian faith. In fact, one classic expression of this view reduced Christianity to three beliefs: (1) The fatherhood of God (2) the infinite value of the human soul and (3) the law of love to God and neighbor. Historic Christians—then called fundamentalists but with a different connotation than today—resisted this reductionism, and it led to serious splits among various Protestant denominations. In my own Presbyterian heritage alone, you can find dozens of splits and schisms among those who claim that others had left the faith.

I discovered that the problem facing the college students in my town has been repeated again and again throughout history. It is the problem of truth versus unity. This problem poses an unsolvable dilemma for Christians who buy into it. And I unknowingly bought into it for many years. The problem comes down to this. If Christians choose to emphasize some aspect of Christian teaching as essential, then they end up separating from those who do not hold that teaching. On the other hand, if Christians attempt to be one in Christ and follow Christ’s teaching on unity, then they must end up saying that certain teachings are not essential. The attempt is to include each group with different opinions while holding that those opinions are of little or no importance. This dilemma pits truth against unity, and requires us to choose either one or the other, but not both. The great challenge facing Christians today is how we can have both truth and unity.

For many years I could see no way out of this dilemma. The more specific some Christians become in their doctrines, the more other Christians had to be distanced from them in a visible manner. The only alternative was to de-emphasize doctrine and to embrace as wide a group of Christians as possible. For the first group, right doctrine is one of the controlling marks or features of the Church. If you don’t have right doctrine, they say, you don’t have a Church. The second group takes unity without doctrine as the defining characteristic (mark) of the Church. If you don’t have unity with love, they say, you don’t have a Church. But such unity was at a great price. It has unity only by downplaying the importance of the content of the faith. How could this dilemma be overcome? As I read and reread the New Testament, it becomes clear to me that the apostles made no choice between doctrinal truth and unity. If the Church is built on the foundation of the apostles and prophets, as Paul says in Ephesians 2:20, then only apostolic doctrine will protect against seriously wrong beliefs (heresy). And only apostolic unity will protect Christians from seriously wrong division (schism). In short, if the apostles were here today, they would not choose truth or unity. They would embrace both truth and unity.

The Problem of Unity in Paul’s Letters

The dual problems of schism and heresy in the Church didn’t begin with Protestantism. Schism is the act of willfully separating from the Church. Heresy is teaching something that is contrary to the Gospel, the Scriptures and the teaching of Christ. Schism is a sin against love; heresy is a sin against truth. These problems began not more than twenty years after our Lord Jesus ascended into heaven. The New Testament writers themselves attest to the presence of false teachers within the Church. They also speak of those who have cut themselves off from the fellowship of the Church through attempts to break up the body of Christ (schism). In fact, many of the letters in the New Testament were written to handle precisely these two reoccurring problems.

Paul’s letters to the Corinthians indicate severe problems involving a party spirit in the Church and a denial of apostolic authority. In I Corinthians alone, Paul deals with schism (1:10-17), misunderstandings of his apostolic ministry (Chapters 3 and 4), problems of gross immorality (Chapters 5 and 6), marriage (Chapter 7), legalism (Chapter 8), liturgical abuses (Chapter 11), conflicts over spiritual gifts (Chapters 12-14), and denial of the resurrection (Chapter 15). This is a list that would keep a modern pastor busy for the rest of his life. What’s most important for our purposes is his opening section on divisions in the Church (I Cor 1:10-17).

We must place ourselves back into the position of Paul’s original readers, if we are to understand his teaching. When Paul’s letter arrived at Corinth, the people of the church there were divided along party lines that were identified by the names of various leaders.

Each one of you says, “I belong to Paul” another says, “I belong to Apollos” another says, “I belong to Cephas (Peter). Still another says, “I belong to Christ.” (I Cor 1:12)

The first three groups identified themselves with certain men as if their own leader had special access to the truth. For example, those who followed Paul denied that Apollos and Peter had the true Gospel. What about the last group, the Christ party?

Maybe they were tired of all the denominations and decided just to follow Jesus pure and simple. To anyone who knows the history of Western Christianity over the past four hundred years, this is exactly what has happened again and again. Various leaders arise who don’t intend to start a new denomination as such, but their followers begin to identify themselves almost completely with their leader. When these denominations fight with one another long enough, someone says, “Christ is lost in the confusion” and determines to get back to Jesus himself. These “Back to Jesus” movements inevitably distance themselves from other mere denominations with the confidence that they have some special access to the true Christ. The similarity between what happened in Corinth and modern Christianity is uncanny.

What is sadly striking is how modern Christians have completely ignored Paul’s solution to this problem. Paul did not accept a denial either of truth or unity. Any lack of commitment to apostolic witness is a denial of truth. Any lack of unity in the Church is a denial of the one body of Christ. Let’s look at Paul’s words more closely.

I appeal to you, brothers, through the name of our Lord Jesus Christ that you all agree and that there be no divisions (schisms) among you but that you would be knit together in the same mind and the same opinion (I Cor 1:10).

Paul categorically rejects the possibility of divisions in the Church. The strength of his conviction is shown by his phrase, through the name of our Lord Jesus Christ. When Paul makes his appeal through Jesus’ name, he exercises the apostolic authority that comes from Christ himself. To appeal through Christ’s name is to command through Christ’s character. There must be no divisions in the Church because Christ is one and his honor is at stake. The existence of divisions in the Church contradicts the nature of the Church and of Christ himself. “Is Christ divided?” Paul asks in verse 13. Of course not. Given what Paul teaches in verse 10, it is beyond comprehension how any Christian could ever justify leaving the Church and starting a new one.

What kind of unity is Paul urging here? Precisely the most difficult kind to achieve, doctrinal unity. Paul’s solution is not to urge love at the expense of truth but unity in truth. His words are, “that you all agree … and … that you would be knit together in the same mind and the same opinion.” Agreement means literally saying the same thing. The same mind means agreeing in beliefs and teachings. The idea that there could be unity among Christians without doctrinal unity is completely foreign to Paul’s thinking. This is why Paul asks some rhetorical questions in verse 13: “Has Christ been divided? Paul was not crucified for you, was he? Or, were you baptized in Paul’s name?” To divide the Church is to attempt to divide Christ since the Church is the body of Christ. Baptism signifies and imparts Christ to the recipient so baptism in any other name is impossible for a Christian. Paul’s teachings are clear. The Church cannot be divided so Christians must embrace Christ’s Church without divisions and must be unified in both love and doctrine.

How does Paul’s teaching help us solve the problem of Christian disunity today? This passage of Scripture doesn’t solve every problem, but it does provide the indispensable foundation by showing how limited are our choices. If we follow the pattern of modern Christianity, we are forced to choose between the two aspects of the faith that are joined together by Paul. Western Protestantism has been forced into a dilemma that Paul rejects. Paul will not have faithfulness to truth without unity in the Church, nor will he have unity without commitment to truth. The only way to follow Paul’s guidelines is to reject the dilemma outright. The beginning of any Christian unity is to reject unity through negotiation. Unity comes by embracing apostolic truth. Yet embracing truth should not be at the expense of destroying the body of Christ, the Church. The answer does not lie in either/or. It lies in both/and.

The solution to the problem of Christian disunity that Paul hints at in I Corinthians is developed more fully in one of his later letters, Ephesians. The Fourth Chapter of Ephesians contains Paul’s rich teaching on unity.

As a prisoner of the Lord, then, I urge you to live a life worthy of the calling you have received. Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace. There is one body and one Spirit—just as you were called to one hope when you were called—one Lord, one faith, one baptism; one God and Father of all, who is over all, through all and in all (Eph. 4:1-6 NIV).

Paul makes two kinds of statements in this passage of Scripture, exhortations and factual truths. The exhortations (e.g. be humble) are the goals for which he urges us to strive. The factual statements are those truths which provide the foundation of what he is exhorting us to do. In essence, Paul says we should be united because there is only one Church founded by one Lord and indwelt by one Spirit. Let’s examine the exhortations and factual statements in this passage more carefully.

Paul’s exhortations recognize that it is possible for Christians to be divided. Unlike Corinth, the Church in Ephesus didn’t have any obvious problems of schism but the problem of division was always lying under the surface. In Chapter 2, verses 11-22, Paul speaks of the wall of partition between Jews and Gentiles that Christ has destroyed. Most churches of the New Testament times consisted of Jews and Gentiles—a problem evident in Galatians—and this ethnic difference always posed a problem for unity. Paul’s exhortations to unity then in Chapter Four are not empty. There are two sides to his commands. One is the gentle side and the other is the diligence required to maintain unity. Humility, meekness and patience are the key attitudes that will preserve the unity of the Church. Forbearance toward fellow Christians is an essential instrument of unity.

At the same time, diligence to keep unity is essential. When Paul says in verse 3 that we should be diligent to maintain the unity of the Spirit, he is teaching that unity is a gift of the Holy Spirit, not something we produce. The phrase unity of the Spirit could be translated the unity that comes from the Spirit. What the Spirit gives we must work hard at keeping. The way to do this is through the bond of peace but not an ordinary peace. Our Lord told us he would give us his peace (cf. Jn. 14:27). The Spirit’s peace is Christ’s peace through the Holy Spirit. Since Christ is one, his peace also binds together believers into one body. Even if Christians are divided, their divisions are not permanent or irreparable. The bond that Christ’s peace produces can overcome all human divisions. The facts of division today might discourage us from believing that Christian unity is ever possible, but Paul would have us rise above our own limitations by looking to a much greater power. Paul begins this section 4:1-6 with the word therefore (then in the NIV). This transitional word invites us to examine the previous verses which tell us that God is able to do far above what we can ask or think:

To him who is able to do immeasurably more than all we ask or imagine, according to his power that is at work in us, to him be glory in the church and in Christ Jesus throughout all generations, for ever and ever! Amen. (Eph. 3:20, 21 NIV)

Christian unity is not possible within the limitations of human powers, but God is far beyond our limitations. That’s why Paul stresses that God far exceeds our expectations. Paul’s hope was in the power of God, but it is not an abstract power that had no relation to our world and its needs. He speaks of God’s power that is at work in us which is why he also wants glory in the church. Paul’s exhortations to unity are based upon the solid confidence that God is working in the church to do what we do not think is possible. All that is required on our part is humility, gentleness and diligence. These virtues are required if unity is to be achieved, but they are also gifts of the Spirit. In short, the unity that we desire is beyond our power. We cannot create unity. All we can do is maintain the unity the Spirit gives. God can create Christian unity because he has already provided the foundation of that unity in the Church.

Paul’s factual statements begin in verse 4, there is one body etc. These statements equally recognize that it is not possible for the Church to be divided. Christians may be divided, but the Church cannot be. The foundation for our overcoming divisions among Christians is that God has already provided the unity we seek. This is important because Christians often speak of the church as divided as if there were many churches in the world. On a physical level, this is true; there are many churches. Paul obviously knew of churches in many different locations throughout the world and he sometimes uses the term church to refer to particular congregations. For example, he wrote to the churches of the Galatian region of Asia Minor (cf. Gal 1:2).

Yet in Ephesians Paul says that there is one body of Christ. His statements cannot be casual, off-hand remarks for two reasons. He makes the same point at length in I Corinthians Chapters 12-14. And here in Ephesians 4, Paul couples things that are on the same order of existence. What things are one? One body, one Spirit, one hope, one Lord, one faith, one baptism, one God and Father of all. Paul lists seven things here that cannot be divided and sums up the faith by invoking each member of the Trinity.

The one Holy Spirit cannot be divided. The one Lord, probably referring to Jesus, cannot be divided. The one God and Father cannot be divided. If God himself cannot be torn apart or divided, what about the remaining four things that also are said to be one. How many hopes does the Christian have? There is but one hope, the blessed hope of Christ’s glorious appearing (cf. Tit 2:13). How many faiths are there for the Christian? Only one. What about baptism? Only one Christian baptism. If these things are true, then it is also true that there is only one body of Christ, i.e. one church. The reality of only one church is the foundation to which Paul calls us. We can be unified as Christians because there is only one church. The Church of Jesus Christ can no more be divided than God himself can be divided.

Paul’s teaching has profound implications for our search for visible unity. The cycle of choosing either truth and division or unity and compromise is broken by Paul’s understanding of the Church in I Corinthians 1:10-17 and Ephesians 4:1-6. When the scepter of disunity raises its ugly head, we must do two things Paul teaches. First, we must return to the same Gospel that the apostles taught. Paul sought to correct errors by reiterating the truths of the Christian faith. These truths provide us with the objective basis for calling into question all the individual agendas of various parties.

Paul called the Corinthians to unity by emphasizing the one indivisible Christ and the baptism he commanded (I Cor. 1:13). He calls the Ephesians to unity based on the same Lord and his one Church. To embrace apostolic truth means to embrace the unity of the Church that already exists. The second essential step is to seek humbly the unity that the Spirit gives and reject our own contrived unity. Such will take all the gentleness and meekness we can muster by the Spirit’s power. But one way we’ll achieve such gentleness is by acknowledging one Lord, one faith and one baptism.

That acknowledgement should produce within us a willingness to relinquish our own agendas for unity and make sure that we adopt Paul’s divinely inspired agenda.

Paul’s teaching helps us overcome two tendencies repeated throughout the history of Christianity, reductions and additions. Returning to the Gospel means that these two errors must be avoided. Reductionism is the attempt to make Christianity less than the fullness of Jesus’ teaching and work. This can happen the way it did in Protestant

Liberalism by reducing the content of the Gospel to a few broad guidelines.

Liberalism was a Christianity without Christ. It can also happen by reducing the Christian life to accepting Jesus as your personal Savior. Both forms of reductionism are not hypothetical; they both have occurred in twentieth century Christianity. They both betray the Gospel because they do not teach everything that Jesus commanded (cf. Mt. 5:18,19; 28:20). The other tendency is additions to the Gospel. Additions are teachings added to the faith that are not consistent with the principles of the Gospel.

Additions are not the same as clarifications. Clarifications are doctrinal or creedal statements that explain the Gospel and its implications. They are necessary when the culture in which the Gospel is preached misunderstands it. Catholicism has been one of the primary targets with this criticism in the history of Christianity. As a Protestant Christian, I believed that doctrines of Mary were such additions. They are not the Gospel, I used to say. They are unwarranted additions. The problem of course is how we distinguish between legitimate clarifications of the Gospel and illegitimate additions. But the answer lies already in what we’ve seen in Ephesians Chapter Four.

Just as there is one Lord, one faith and one baptism, so there is one Church. And that one Church is God’s chosen instrument to distinguish between legitimate clarifications and illegitimate additions. This is why Paul calls the Church the pillar and foundation of the truth (I Tim 3:15). And the Church of history shows how God the Holy Spirit has guided the body of Christ to perform this task through the councils of the ancient Church. The historic Church is not the ultimate basis of the truth. The God who revealed the Gospel is the ultimate foundation of truth. The Church is his servant. It is this one God in the person of Christ who committed the Gospel to the Church. And it was the apostolic founders of the Church (and their cohorts) who wrote down the Gospel in many forms and ways in the New Testament. When there’s a question about the content of the Gospel as expressed in Scripture, it is to the Church that we must turn to distinguish between legitimate clarifications and illegitimate additions.

Paul’s teaching on the unity of the Church provides some of the most powerful answers to the problem of Christian disunity. They have been there in the New Testament all along, but often we have failed to read and understand carefully the implications of his teaching. We must be satisfied with nothing less than the one Church that Jesus founded (Mt. 16: 13-18). It was that Church which Paul and the other apostles worked to establish. At the same time, the Church of Jesus Christ cannot be a church of our own contriving. It must be the way Jesus Christ wants his Church to be. It must be the Church that Paul speaks of in Ephesians 5:21-33. It must be the Church which Christ loved and for which he gave himself (5:25) and which he sanctified by the cleansing with the washing of the water in the word (5:26). It must be the Church he will present to himself, glorious without any spot or wrinkle (5:27). This Church is the bride who has adorned herself for the wedding supper of the Lamb (Rev. 19:7). This personal language of marriage and love points back to a kind of unity for which our Lord prayed.

One People with One Heart: John 17

No passage in all of Scripture compares to the loveliness and tenderness expressed by our Lord in his high priestly prayer in John Chapter Seventeen. If we can imagine the agony of his experience, we can see the great generosity of his heart as he prayed for his own. Here we see Jesus in intimate communion with the Father as he realizes that his earthly journey nears the end and he is returning to the Father.

Our Lord’s high priestly prayer shows us the goal of life, union with God for eternity. His own unity with the Father is the basis of our unity. He asks for the Father to glorify him on earth (Jn. 17:1) that he may pass that glory on to his own disciples. And here we see what kind of unity our Lord desires for us. He wants us to experience the kind of glory he had with the Father before the world existed (Jn. 17:5). Jesus’ disciples were given to him by the Father (Jn. 17:2, 6) and he has faithfully given them the Father’s truth (Jn. 17:8). When Jesus prayed for the unity of his followers, he prayed that their unity may be the same as what he and the Father had (that they may be one just as we are one, 17:11).

Verse 21 gives us a more explicit truth, that they may be one just as you, Father, are in me and I in you, that they also may be in us. Not just any unity will do. Only the complete unity that reflects and comes from the Trinity will answer to our Lord’s request. The mutual indwelling of the Father and the Son (theologically called circumincessio) provides the source of the Church’s unity. This is why unity by negotiation is so impotent. All the human contrivances we can conceive will never unify Christians in the manner Jesus prayed for. Only the indwelling fullness of the great Triune God will accomplish unity. How does that happen? Verse 22 tells us, I have given them the glory you (Father) gave me that they may be one as we are one.

Unity among Christians comes only by the reception of divine glory that Jesus brought to our world. Recall that John told us that Jesus as the Incarnate Word (Logos) was full of grace and truth (Jn. 1:14) and that from his fullness we have all received (Jn. 1:16). That grace, truth and glory that fills his being is now ours through his earthly ministry. As he prays for us, our Lord wishes that same glory to so fill the hearts of his faithful ones that divisions may cease and the divine oneness may fill the Church.

Believing that unity among Christians is possible would be a sham if it depended on human ingenuity and effort. But God can accomplish in moments what human beings never can. The glory of Jesus Christ can fill each and every Christian with such grace, love and truth that he or she will want the kind of unity Christ provides. What is required on our part? Jesus says that we must keep the message (word) which he delivered from the Father (Jn. 17:6). That is why commitment to his truth is so vital. We must put our personal agendas aside and follow his path. When Jesus prayed, Holy Father, keep them in your name (Jn. 17:11) and sanctify them in your truth(Jn. 17:17), he was asking that the truth and character of the Father’s person might be the center of our lives. Nothing less will achieve his goal of the union of all God’s children in the Father.

Mary: The Sign of Unity?

How can Mary help in promoting Christian unity? Many may feel the weight of disunity among Christians and long for a greater oneness in Christ, but can Mary really give us that greater oneness? Mary has been a source of division between Catholics and Protestants for a long time. What good will focusing on Mary bring? How can Christians be one when the very Marian devotions so precious to Catholics are viewed as idolatrous by Protestants? To human eyes, it seems that almost any other Christian doctrine would be better suited to bring unity than doctrines of Mary. And if we think of Mary just as a set of doctrines, that would be true. But Mary is more than a set of doctrines. Mary is a person. She lived her life on this earth as the mother of our Lord with her own character, mind, and idiosyncrasies. These things are true regardless of what we believe about her. Mary is what she is apart from our beliefs.

There is one unmistakable fact that we must remember about the real Mary: the Son of God lived in her womb for nine months. This is how Mary can be an instrument of unity. She united the Logos, the second person of the Trinity, with his human nature in her own body. Mary united more than any human being has ever united. She united God and man in the small confines of her own womb. Ponder this amazing reality. In Mary’s womb, heaven and earth were joined, not as two separate realities, but perfectly united in the one person of the Son of God. No wonder it says that “Mary treasured all these things and pondered them in her heart” (Lk.. 2:19). It is a reality beyond words. Mary was the instrument of unity for the body of Jesus Christ and this is why Mary has long been thought of as mother of the Church. The Church is the body of Christ and Mary was the mother of Christ’s body, both physically and mystically. We’ve seen in the biblical texts discussed in this article that Jesus Christ is the key to unity among Christians. But the one Savior Jesus Christ would not be what he is—the perfect God-man—without Mary’s being the means of uniting his divine and human natures in one person.

Mary’s example of obedience and discipleship also form the foundation of unity. Mary gave herself unreservedly to Jesus her Son. Every Christian wants to be an obedient disciple of our Lord and needs examples of obedience to do so. Mary was filled with grace and this allowed her to listen to the commands of her God without delay. Mary was on earth what every Christian will become in heaven, filled with grace. Obedience means a readiness to say “yes” to God, a spirit of humility that says fiat. We’ve seen in this chapter that unity cannot be achieved through negotiation. It must come through obedience to the apostolic teaching given by Jesus to Paul and the other apostles. Without a willing spirit, we can never achieve God’s desire for unity. Mary’s life of obedience and discipleship calls us to unity with God through obedience.

How can Mary help Christians find a greater unity among themselves? Mary has been a source of disagreements between Catholics and Protestants for a long time. Of all the truths Christians believe, Mary seems to be the least likely of all to help with the problem of unity. But we must recall the kind of unity we should seek. If we were looking for unity through negotiation where each side gives up something for the sake of a common faith, then Mary would indeed be a stumbling block to unity. Yet the unity we seek is not human but divine. Its source is the divine life of Christ the Redeemer. It is that unity for which he prayed when he said, “Father, that they might be one.” This kind of unity doesn’t come from each group of Christians giving up some belief or practice for the sake of unity; it comes from each individual or group submitting to the authority of Christ and from the work of the Holy Spirit bringing oneness where it is humanly impossible. Like salvation itself, Christian unity is not within the grasp of human power. All we can do is open ourselves up to the ministry of the Spirit to produce the unity that is impossible through negotiation.

It is because Mary has been such a stumbling block for Christians that a fuller embracing of her person and role will achieve a greater unity than we might expect. If we view Mary apart from Jesus, then Mary cannot help us. Yet she was never meant to be seen apart from her Son. Just as the Magi found Jesus “with his mother” (Mt. 2:11), so we find Mary involved with her divine Son, cooperating in his work and plan.

We cannot solve the problem of how to be one in Christ. Not by negotiation, not by one or the other side caving in. But God can solve our problems. God specializes in the impossible, just as he once said to Mary (Lk. 1:37). If the Holy Spirit can create within the womb of the Virgin Mary a new entity—the unique God-man—then he surely can bring together Christians divided by history, suspicion and misinformation. Perhaps it’s time for us to stop trying to be unified and let God do what we have failed to do.

No one can see precisely how this will happen, but we know it won’t happen without embracing the fullness of salvation in Christ himself.
