But, let's do something practical, as well. Why not encourage every priest in the United States to ask one man, over the course of the next year, to consider the priesthood as a vocation?
Angels will never recruit anybody to the religious life, but flesh and blood human beings will.
I would assume that all arch/dioceses have retreats for young men (and even some older ones) to attend and hopefully move along the journey of discerning a vocation.
I know here in the PDX Archdiocese the Benedictines just had one.
The Archbishop just conducted one as well -- and our priest spoke about it at every Mass for two weeks. (And it was free for those attending!)
Just how do you know angels will never recruit anyone to the religious life? They seemed to be able to recruit The Virgin Mary and St. Joseph.
