Was he married like Peter was?
Was there some problem with being married? Remember that the qualification of being a bishop included having a wife.
Peter left his wife and followed Christ. This is not about the “personal”life of Peter or the Pope. It is about the ONE true Church. The rest of course in Hillaire Belloc famous words, a fourteen centuries later, how Protestantism “spawned a cluster of heresies” unlike any other before that time.
There’s no evidence that he was married. The next “married Pope” was St Hormisdas (died AD 523), but he was a widower when elected. He was also the only Pope to have been the father of a Pope.
