Celibacy does relate to service to the church, whether it's requirement is a good thing considering the shortage of priests, the resulting lack of heterosexual vocations, and the very frequent violations of the discipline. What best meets the needs of the Church today?
The 21 Churches in the Eastern Rites of the Catholic Church which ordain, as a norm, married men, are all experiencing a shortage of Priests as is the Greek Orthodox Church which also ordains married men and pays their clerics quite a bit more than the Catholic Church does. The "do away with celibacy and all our problems will be solved" argument is, at best, specious.
What best meets the needs of the Church today?
Obedience and fidelity to God ,just as it has always been.
