Perfect and Perpetual. As they have done for lo, these two thousand years? Cleric and lay alike, we are all engaged in the quest for perfection. Its attainment is another story.
In regard to celibacy, chastity, or as you and Canon Law so delicately put it, "continence," check out Willa Cather's "Death Comes to the Archbishop," or Morris West's "Shoes of the Fisherman." Maintaining this discipline is a constant struggle for the Church, and sometimes the results are rather better than at other times.
That's one of the reasons there was a Reformation, and a Counter-Reformation. Work in progress, and all that. The sad tale of Father Cutie, IMHO, pales in comparison the story of the clerical monsters guilty of the (homo)sexual abuse of children. It especially pales in comparison to the knowing connivance of the unclean bishops who took part in the cover up of this world wide scandal.
I hope and pray Father Cutie takes his punishment like a man and comes back a better priest, and a better man, as have erring priests over the past centuries before him.
