Early christianity started as an apocaloyptic cult......why should we be afraid of old apocaluptic writing?
Besides... the writing in Peter "2 Pet 3:3, 4: "For YOU know this first, that in the last days there will come ridiculers with their ridicule, proceeding according to their own desires 4?and saying: "Where is this promised presence of his? Why, from the day our forefathers fell asleep [in death], all things are continuing exactly as from creation's beginning."...was made vera late, probably around AD 130-150. Probably a lot of christians got tired of waiting for the coming.
