Jimmy Akin has a post up that's worth noticing.
The post's purpose is to be part of a series of posts dealing with a particular current-events scandal involving a philandering priest.
But in order to set up the necessary background information for understanding the scandal, Jimmy lays out a concise (really) twelve-point explanation of the nature of the rule about priestly celibacy: what it means, why we have it, what are the exceptions, why it's possible to disagree with the rule in good faith, etc.
Worth checking out if you need a refresher on this information yourself.
