Well it certainly is not natural. Which is why enforced celibacy leads to so many problems.
Yes, there’s zero requirements for that in the Bible. Peter had a wife as did most disciples that I know of. Paul I don’t think did, but he travelled so much.
It is truly amazing to me that some people on FR can be so right on certain subjects and comment with great insight and then on other subjects like celibacy be beyond dumb and parrot pure BS.
I must mention that the celibacy is not forced.It is chosen.Men know what the price is to be a priest.The difficulty of living it must be tremendous.
