Catholicism is shown to still exist in some form in the 31st century, as the show makes several references to the "Space Pope": in the opening titles of "Hell is Other Robots" (stating that the show has been "Condemned by the Space Pope"); in "A Bicyclops Built for Two", with Bender's rhetorical question "Is the Space Pope reptilian?"; and in "I Dated a Robot", in an endorsement at the end of an educational film ("Brought to you by the Space Pope"). In the last of these, a graphic displays a picture of the Space Pope as a reptilian alien in Papal vestments, encircled by the words "Crocodylus pontifex". Additionally, in the episode "Put Your Head on My Shoulders", Fry and Amy Wong have a lighthearted conversation about their parents' expectations of them; Fry remarks, "What am I, the Pope?" to which Amy replies, "Yeah, and if you were the Pope they'd be all, 'Straighten your Pope hat,' and 'Put on your good vestments!'" In the sixth season episode, "The Duh-Vinci Code", the cast travels to Rome (announced as Future-Roma), where the Space Pope directs the ship's landing at the Vatican. A few episodes later, in "The Silence of the Clamps," the Space Pope is shown conducting the wedding of the Donbot's older daughter.
