I never said it is a requirement, but Jesus expressed admiration for celibacy (Matthew 19:11-12) and he made a personal choice to be celibate.  So it is not a requirement but, according to Jesus, it is a laudable vocation.  There is room for both celibate and married priests.  The crucial issue is the ordination of women, not celibacy.  Personally, I would be in favor of ordaining celibate women first.  Celibacy is clearly a matter of discipline.  It is the *doctrinal* patriarchal inheritance that must be overcome!
