D'Oh! Top 10 (Plus One) Religious Episodes on The Simpsons

The Father, the Son, and the Holy Guest Star (Catholicism)

Thrown out of public school (again), bratty son Bart is sent to Catholic school, where he meets a cool priest, played by Liam Neeson. Homer, seduced by bingo, a pancake supper, and the concept of confession and absolution, decides that he and Bart should convert to Catholicism. Marge panics, and with her minister, Reverend Timothy Lovejoy, and her evangelical next-door neighbor, Ned Flanders, the trio proceeds to refight the Reformation. Lovejoy accuses Homer of being "under the spell of a man in a pointy white hat." But Bart reminds everyone, before bloodshed erupts (again) between the Protestants and Catholics, to remember that they share the same faith.

"It's all Christianity, people. The little, stupid differences are nothing next to the big, stupid similarities." --Bart Simpson
