In actuality, the percentage of Catholic Priests that are pedophiles is no higher than it is in any other church. It's just that the Priests, and the Catholic Church, get all the publicity.
I see articles about Protestant Ministers, Rabbi's, teachers, coaches, etc. being arrested for crimes against children, and they are usually a one time writeup. But, if a Priest is arrested, it gets written up day after day, after day.
This has absolutely NOTHING to do with Celibacy, or with homosexuality. Pedophiles are NOT aroused by adults, they are sexually attracted to children. Any position of authority or leadership of children tends to attract pedophiles.
The Eastern Rites of the Catholic Church have had married priests all along. They also have pedophiles, even married ones. So do all of the Orthodox Churches have married Priests, and they also have some pedophiles. (By the way, in both the Eastern Rites, and the Orthodox Churches, Bishop's are NEVER married, just as Bishop's are not married in the Roman Rite of the Catholic Church
The Roman Rite has also instituted married Deacons, who are also ordained Ministers. They can marry people, do burial rites, etc. If the Pope does allow married Priests, the obvious move would be to put those married Deacons through a "Quickie" Seminary program, and ordain them as Priests. And, possibly allow some of the men that left the Priesthood to get married, to come back and function as Priests again.
I doubt if those already ordained, who have taken a vow of Celibacy would be allowed to choose. But Seminarians would be allowed to choose. I suspect that it would work like it does in the Eastern Rites and the Orthodox Churches, if you want to get married, you do so before you are ordained. If you want to try to advance and become a Bishop, you do not marry. In all cases, ordained ministers (Priests or Deacons) can not remarry if their wife dies, or they should get a divorce.
