Hello, well, let's just say the book explains a lot.
Because the culture of the seminary permeates Catholic life for the folks at the bottom of the food chain, the laity.
People who have ishoos with Church teaching seem to be in positions of authority in Catholic education.
People who leave the priesthood and religious life seem to get jobs as chaplains and teacher of RE in Catholic schools. As a teacher you have a captive audience in front of you.
From every perspective a disaster, particulaly if you are brought up with a world view that people in authority in the Catholic Church believe what it says on the tin and have other people's welfare at heart. Then you end up with young men being rejected from the priesthood and believing that this must be right. They got it wrong or worse there is something wrong with them. What happened next to the man who returns from the seminary, in his words in disgrace, back to his family who cannot understand why in a time of a crisis in vocations, his has been rejected. I wonder what he did with the rest of his life?
