William Paley's classic defense of Christianity, "Evidences of Christianity", was sometimes required reading at universities throughout the 1800s. Even those who disputed Christianity were expected to interact with Paley's arguments. Ironically, while many people past and present believe that the evidence for Christianity is discredited, Paley's "Evidences" is as fresh as ever, because many people still find his arguments as compelling as ever. In fact, it could be said that the fact that Christianity's defenses do not need to be updated every century is testimony to the fact that it is in fact true.
