I read this thread and noted that no one picked up on the fact that the Roman Catholic Church does admit married men to the priesthood. It's called the "pastoral provision". Google that or see the link www.ewtn.com/library/ANSWERS/MARPRIE.htm

So being married is itself not an impediment to being a priest. It's just that this option is only allowed for priests who were ordained in another rite and were married before converting to the Roman rite.

This is true, but its not common. If these priests' wives die, they are not permitted to re-marry. Same way for permanent deacons, they can be married when ordained, but are not permitted to re-marry after the death of their spouse.
