The Decameron

In one story, the merchant Giannotto di Civignì tries to get his Jewish friend Abraham to convert to Christianity. Abraham says that he must first go to Rome, to observe the clergy and see if they lead holy lives. This worries Giannotto. He fears that Abraham will discover how debauched the priests are. And that is exactly what happens. Abraham, returning home, reports that the Roman clergy are all sots, satyrs, and sodomites. Then he invites Giannotto to go with him to church, where he intends to be baptized. If the Roman church survives, he says, despite the debauchery of its representatives, then it must be endorsed by the Holy Spirit, and he wants to join the winning team.

What can  tell you? It made me laugh.
