Via PZ, it turns out that there's a passage in the Book of Matthew that for some reason doesn't get read on Easter Sunday:
50 And when Jesus had cried out again in a loud voice, he gave up his spirit.
51 At that moment the curtain of the temple was torn in two from top to bottom. The earth shook, the rocks split 52 and the tombs broke open. The bodies of many holy people who had died were raised to life. 53 They came out of the tombs after Jesus’ resurrection and[e] went into the holy city and appeared to many people.
The fact is that the most devout Christians simply have not read the Bible and do not know what is in it. If you want to keep the faith, you can't just sit down and read the whole damn Bible because you will very quickly discover that it is full of nonsense, self-contradiction, exhortation to evil and injustice, and that God is one nasty, repulsive son of a bitch.
If the preachers weren't embarrassed by the idea that not only Jesus, but a whole lot of other folks, were resurrected, they'd at least mention it once in a while. But even though it's still in the Bible, it's completely censored from the Easter story and is carefully skipped over in church. Next time you get a chance, you might ask your own guy in a dress about this.
