This story is disgusting and repulsive. But a shock? How can it be after what we've gone through in this country over the past few years as victims of clerical abuse have come forward in droves to tell their stories.
The overwhelming majority of men who join the Catholic priesthood are good, Godly and devout. I fear though, that the church's view on priestly celibacy encourages a subset of sick, confused and tortured men to seek a life in which their demons are held at bay (presumably) by celibacy--only to find that they cannot control their nature.
I was born a Catholic and I have immense respect for the church and its institutions. But the church has simply not been straightforward enough on this crime, and it has not explained why it is that this is not an issue in faiths without clerical celibacy.
