If I remember correctly, canon law states that if a man has a problem with the celibacy, he is obligated to leave. Diocesan priests make a promise not to marry, but vow obedience to the bishop. They can accumulate as much wealth as they want.
I have researched this subject of priestly celibacy for a novel work-in-progress. Priestly celibacy is a church law, and can be changed at any time. Priests already in the priesthood would be exempt from the change if such ever happened. The rules regarding deacons would be followed, only taken a step further. Instead of changing the law in the book, I have simply switched to the Pastoral Provision, since the testimonies of Pastoral Provision priests’ wives are readily available.
I know of a few former priests, my own hometown being rocked by scandal when I was small, and I got to know the family later on. Not only was the man’s wife teaching at our Catholic high school, but he lovingly spoke to me about the subject, and couples used to go to him for pre-nuptial counseling. He said he received a letter thanking him for his service.
He is a widower now.
I don’t see why they can’t be “demoted” to deacon. Their experience can certainly be utilized, and what happened is between them and God. We always want to judge, but God will oftentimes put us in a similar situation, and we find ourselves begging for mercy.
