"Ok, for the record, this is like trying to argue that Jesus made the decree that priests couldn't be married. He didn't. In fact, that decree wasn't made until HUNDREDS of years after Jesus died, like most arguments that the Catholic church holds sacred."There are many ways to respond to this. For one thing, the Bible does include Jesus speaking favorably about priestly celibacy. For another thing, there is no reason why the Catholic Church can't talk about things that Jesus did not mention specifically. That does not negate the Church's authority or make it irrelevant.
But let's respond to this objection from a historical standpoint. Our commentor mistakenly believes that priestly celibacy was invented, hundreds of years after Jesus died. That is false; priestly celibacy existed as a practice long before it became a mandatory practice.
In the beginning of the church, there were both married priests (like St. Peter) and non-married priests (like St. John). Different places had different rules about celibacy. Some places had mandatory celibacy for priests, some places had mandatory celibacy for bishops with optional celibacy for priests, and some places had optional celibacy for both priests and bishops.
Hundreds of years later, it was decided that every place should have the same rules, in regards to celibacy. The model they picked was mandatory celibacy for all priests, and this mandate is still in force today. The other models of celibacy all existed with Church approval in the past, which means it is possible (though unlikely) that the Church can return to them.
In fact, England is currently asking if they can adopt a different model of celibacy, due to the influence of the Church of England on their country. I read their petition, and they made some good points, but I believe their points were poorly presented, which might hurt their chances of getting the petition accepted.
