Jesus and St. Paul both encouraged celibacy, but neither mandated it.
The Eastern Rite of the Catholic Church has married priests, and there are married converts from the Episcopal and Lutheran Churches serving as priests today in the Western Church; well over 100 of them.
Celibacy is a discipline, not a doctrine, and the Church won't crumble if the discipline is changed.
In fact, I maintain the Church will have many men willing to serve; many ex-priests would return. An added benefit would be to allow the Church to rid itself of the openly gay priests and seminarians.
Good that you mentioned the Eastern rites of the Catholic Church. They are often forgotten entirely in the US, but in reality there are 21 other rites besides the Latin Rite, and to my knowledge virtually ALL of them allow married men to be ordained.
Further, the Eastern Orthodox (who WERE in union with Rome until the early 11th century) have *always* allowed for the ordination of married men for the parish priesthood. (Monks and bishops are celibates.)
Consider this point. Those who wish to argue against women as priests use arguments from history to point out that Christ didn't ordain women, etc. Fine - except when the arguments from history *support* ordination of married men, they are discarded!
No, changing the discipline on celibacy will NOT "destroy" the Catholic Church - it certainly hasn't destroyed 21 out of the 22 rites, OR destroyed the Eastern Orthodox (whom Pope John Paul II has worked hard to reunify with the Catholic Church. If the Eastern Orthodox WERE reunified, they certainly would not give up their married priests.)
Besides, the Latin Rite *already* ordains married men, when they convert from Anglicanism or Lutheranism, and want to be Catholic priests. In fact, there are more married Latin Rite priests in the USA than there are Byzantine Catholic married priests! Why not just make it possible in general?
Currently, if a married Anglican priest converts to Roman Catholicism, he may be both married and a practicing priest.
No,the answer is clear out the homosexuals priests,live with a Church that is purer and poorer and stronger and maybe even smaller,for a while.Then in an atmosphere of serenity study the scriptures and pray and seek to discern what Christ really wants of his "consecreted followers".
