You are not usually one to voice such sour grapes. Give thanks that this man is answering the call to serve God.
He must have felt something or else he would not have quit as a Lutheran priest. Until we could talk to him, we really can’t tell, can we?
I find it interesting that the Catholic Church has a special dispensation in regard to priestly celibacy for apostates who leave the Catholic Church and then who later become apostates from Protestant denominations.
The Bible says a double-minded man is unstable in all his ways. Here we find that double-mindedness is given a special dispensation. Why not grant the same privilege to faithful Catholics? Why not admit married Catholics who have been faithful to their church and their family the privilege of serving as priests?
