It is completely untrue that celibate priests are more likely to be pedophiles than any other group of men, married or not. Pedophilia affects only 0.3 percent of the population of Catholic clergy, and sexual abusers in general account for less than 2 percent of Catholic priests. These figures are comparable to rates among married men, as non-Catholic scholar Philip Jenkins points out in his book Pedophiles and Priests. Other Protestant denominations have admitted to having similar problems among their own married clergy, so clearly the problem is not with celibacy.
First of all, "celibate priests" are, by definition, not engaging in sexual activity with anybody. Second, I just do not buy into the statistical argument unless the term "pedophilia" is read to exclude "sex" with teenaged boys, in which case perhaps it is true. I don't think that ignoring the problem of active homosexuals in the priesthood is an effective way to defend priestly celibacy.
