From the article, “ I had to admit to God and to myself that I was in love with Yvonne!”
Pretty much says it all, he messed up and so he wants to blame it all on the Catholic Church. We actually had an ex-priest and ex-nun who were married in the neighboring parish, they were mature enough to understand that it wasn’t the Church it was themselves. How they reconciled it with God, I don’t know, but the were both great teachers and worked in lay positions.
It is often the case that those who don’t or won’t hold to the teachings of the Church leave and blame the Church for their own faults without truly admitting any wrong in themselves. You know, it is how a lot of people behave when caught in a lie. They make excuses and blame it on someone or something else when it was all their own fault.
