dwid gave a good summary of the Catholic Church's position. Last I checked, St. Paul is in the Bible so no, the Catholic Church is not "overriding" the Bible.
It is interesting to note, and Don alluded to this (though surprisingly without seeing the obvious conclusion), that the (not celibate) protestant clergy, and indeed ALL men
http://www.thedailybeast.com/newsweek/2010/04/07/mean-men.html are just as likely to commit pedophilia as Catholic priests. Surprising given the public perception and media coverage, but it shouldn't be surprising to members of this board..."Wait the media is lying?"
So why do you have a problem with them being celibate if it's proven that there is NO chance of reducing pedophilia by having them not celibate?
dwid is right that it is not Church dogma that priests be celibate, but I disagree with him that they should consider changing it. The Church, and St. Paul, wanted men who could give their whole lives to ministry. If celibacy drives some young men away from the priesthood then God doesn't want them to be priests. And that's fine, there's nothing wrong with them for not wanting that for the rest of their lives. Interestingly, I have heard that Anglican-use priests who are married and converted to Catholicism have a hard time of it. Balancing your family and your church family is pretty tough, apparently. I think it's fitting and makes sound sense to have a celibate clergy.
