Nevertheless, it denies them their calling.
How so? St. Francis was never a priest, he was never even a great preacher. God calls us to use the gifts we have, and his was to be, as I think he once says. to be God’s jester. He drew men to himself as a magnet draws iron fillings. I have been reading about the witness given by Fr. Emil Kapaun, the army chaplain in Korea. Just a simple priest from a small Czech settlement in Nebraska, but he was able to led men far better than their officers. The kind of guy who could jump into a foxhole where you were cowering as bullets flew over head, open his coat and offer you an apple.
Okay, and if the church asserts that a valid "calling" to the priesthood presupposes a "calling" to the virtue of apostolic celibacy, then ... ?
