It is obvious from the New Testament and the history of the early church that presbyters and overseers were married (to a wife, not the Church). Institutionalized celibacy is not found in the Old or New Testaments. Yes, there are people in the Bible who did not get married, but there is no order or caste or group of people who are, by virtue of their position and duty, to remain celibate.
Now, there are practical advantages for priests to be single. They are more mobile and cost effective. If a church wishes to not have married men as priests for practical reasons, then so be it. Don’t try to dogmatize it.
Who is doing that?
Celebacy is a valuble discipline, as you note. Not a dogma.
