Are Priests different from other men?

The Catholic Answers

As human beings—no; as called, not to the state of marriage, but to the Priesthood—yes. For this reason, whilst like all others who for one reason or another do not marry, they are obliged to avoid all sins against chastity; they also take upon themselves an additional obligation to do so under pain of sacrilege by vows of chastity offered to God.
