Priests take a vow of celibacy, but they are human and the body's urges call.
The statement I quoted with the words "deeply rooted" came from a committee, not the pope. That remark and a couple of other responses tend toward condemnation of homosexuality as a contributor to molestation, which was not intended by my rather careless partial quotation.

There is no correlation that I know of between homosexuality and molestation tendencies.
