Ending mandatory celibacy would benefit the Church in many ways.  Married priesthood is the Apostolic Tradition preserved in the other Rites of the Roman Catholic Church & in the Orthodox Church.  It would, according to a survey done by the Knights of Columbus among their own sons, increase vocations by 16% among their sons.  THAT says a great deal.  (That was over 20 years ago before so many became disillusioned by the scandals of course.)  My own father and brothers would have been priests & good ones had married priesthood been an option.

There will always be playboys & sick pedophiles, & the sexually immature priests but the specific sexually arrested development we have seen come to light would be more easily spotted if those running formation programs were themselves mature, both married & celibate priests. It wouldn't be the hiding place it has become.

Stil, there are these children & mothers & we are bound by Charity toward them regardless of current clerical celibacy.
