I'm not sure if I understandd the question. But maybe it's relevant to point out that the Cathoic rule about celibacy for clergy is NOT considered doctrine but rather a matter discipline , and one which permits of exceptions. There are, in fact, married Roman Catholic priests, and there are married priests in rites in communion with Rome.
If memory serves me correctly, a priest cannot get married. If a person wishes to enter the priesthood and is already married, I believe the Catholic Church, in some cases, will allow that.
If one is going to interpret this to be directed at the responsibilities of priests, what I pointed out in Titus 1:5-6 would suggest that all priest may marry and have children. Saying that it is a matter of Church discipline that priests shouldn't marry is effectively saying that Paul, while writing this under the influence of the Holy Spirit, didn't know what was best for the Church. That, to me, is like saying God doesn't know what's best.
