How typical a priest was Jack Holland?

This is probably the most asked question I get about the novel and I must say that - luckily for the Catholic church - he is a gross exaggeration.
In my experience of 11 years as a priest and many more beforehand as a seminarian, the vast majority were very good and sincere men. Most of them tried to observe celibacy - with differing degrees of success.
The parish priests I portray in the novel are fictional characters and pretty much caricatures unlike any men I ever met. For the most part they were reasonably bright and kindly souls some of whom may have become a bit shop-worn in their style and approach to ministry.
There would have been a few - mostly younger men - who found that the 1960's gave them leave to follow a different sexual ethic. These would be the priests with girl friends or boy friends.
It would have been easy to keep such behavior from religious superiors when living in a graduate school dorm far from one's diocese and so the incidences would have been greater there.
I don't doubt but that there was a Jack Holland somewhere in the USA but I never met him or one quite so promiscuous.
