"A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behavior, given to hospitality, apt to teach... One that ruleth well his own house, having his children in subjection with all gravity; (For if a man know not how to rule his own house, how shall he take care of the church of God?)" -- I Timothy 3:2, 4-5
"...ordain elders in every city, as I had appointed thee: If any be blameless, the husband of one wife, having faithful children not accused of riot or unruly." -- Titus 1:5-6
With all due respect, no Catholic disputes that married men CAN be ordained to the priesthood. It happens all the time.
Celibacy is a valued tradition. We’re all very aware of the pastoral letters in the NT and their words on the subject.
Ahhh .. I knew someone would post that verse, and it turned out to be you! So what is Paul actually saying? Paul instructs that bishops must be married only once. This verse refers to bishops that were widowers. Paul is instructing that these widowers could not remarry. The verse also refers to those bishops who were currently married. They also could not remarry (in the Catholic Church's Eastern rite, priests are allowed to be married; celibacy is only a disciplinary rule for the clergy of the Roman rite). Therefore, this text has nothing to do with imposing a marriage requirement on becoming a bishop.
