Celibacy of the Catholic priesthood is an administrative policy, it is not based in Scripture nor does it have to be. Democracy and air travel are not in Scripture either.

"and DIVORCE is NOT the unforgivable sin."
Whoever divorces his wife and marries another, commits adultery against her; and if she divorces her husband and marries another, she commits adultery" - Mark 10:11-12
Adultery against a mate is NOT the unforgivable sin, and the sin does NOT require some administrative policy of exchange of money to be forgiven..... NOW there is a different penalty to commit spiritually speaking to commit adultery against the Heavenly Father... As Christ is called spiritually the 'bridegroom', and it will not do well for anyone to be messing around with a fake 'bridegroom', as it is WRITTEN.
The practice of purchasing indulgences was banned over 500 years ago, rendering Luther Moot. Further, indulgences in no way forgive sins. They deal only with punishments left after sins have been forgiven. The definition of indulgences presupposes that forgiveness has already taken place: "An indulgence is a remission before God of the temporal punishment due to sins whose guilt has already been forgiven" (Indulgentarium Doctrina 1).
