According to Jim Episode 2.08 Father Disfigure

Cheryl drags Jim down to the church for the new reverend's mess, which is supposed to be "the next best thing". Jim sees some familiarity on him, and remembers he was the kid he played dodge-ball with back when they were kids. Jim also remembers that he threw the ball so hard at the guy he got a fat lip (and a funny nickname) for weeks (the nickname lasted for years). When Cheryl invites the reverend over for dinner, Jim freaks out, hoping he won't remember a thing. But Jim's hopes go down the drain when the reverend confronts him and later quits the church, giving his inability to forgive Jim as a reason. Feeling guilty, Jim apologizes and even takes on Gracie and Ruby's advice on offering Reverend Pierson a chance to throw a dodge-ball back at him.
