Thanks for this! It's usually those that throw a dollar into the collection basket and think that priests are rolling in money, who say that they think priests should marry. Who is going to pay for housing, groceries, family medical bills, orthodontics, college etc. This has been my argument on marriage in the priesthood from just the practical side. Really wakes them up.
Your response will certainly hold water with those who cannot accept - or comprehend - the all too important spiritual aspects of celibacy: solitary dedication of purpose to God's service, and sacrifice of the flesh to benefit the soul.....and thus his service to other souls.
Regardless of the cited exceptions to mandatory celeibary stated above (which are a very tiny minority of priests), celibacy remains a very important companant to the priesthood. It is much more then a mere "discipline": it is the basis of the "wedding" of the priest to Christ's church.
