Saint John Massias, the Dominican lay brother, had a wonderful devotion to the Souls in Purgatory. He obtained by his prayers (chiefly by the recitation of the Rosary) the liberation of one million four hundred thousand souls!

In return, they obtained for him the most abundant and extraordinary graces and came at the hour of his death to help and console him and accompany him to Heaven.

This fact is so certain that it was inserted by the Church in the bull of his beatification.
