A lot of people wouldn't like how harsh this man is on things like pre/extramarital sex...but whatever, he's a priest, and one has to expect things like that from religious leaders.
He also doesn't pull any punches. This book is not for the faint of heart. He does (did) hard, hard, hard work in some of the most difficult and dangerous circumstances you can imagine. Work that needs to be done on an extraordinary level that most people would rather just turn their heads and look the other way about.
