As the brother of a priest - who has a masters in history and managed restaurants along the way before answering the call - the big moment of decision will be at his diaconate. There, prostrate on the floor, after three years in the seminary, he will be asked if he can make the full commitment to the priesthood. My brother said he has seen guys get up and walk out of the cathedral, realizing the call wasn't for them. And when they walk out, they leave the seminary.
Then again, my brother went to a seminary where there was a bar in the basement of their dorm with beer on tap for the seminarians.
It is a big commitment Grant is about to make and I applaud him for it. Pax vobiscum, sir.
