The question I hear a lot is “The tomb was empty, what’s the best explanation?” They explain that the sleeping guards/disciples stealing scenarios aren’t likely, and therefore, the resurrection is the only option left. I counter that to disbelieve in the resurrection, it is not necessary to come up with an alternative explanation. The sheer implausibility of such a claim, in conjunction with the lack of truly extraordinary evidence is quite sufficient to justify rational disbelief.
What do I personally believe happened? I like the “urban legend” theory. Seeing Jesus killed destroyed the apostle’s faith in Jesus. The true Messiah would never be killed before he fulfilled the prophecies. And since Jesus didn’t throw off the Roman yoke, establish Yahweh’s kingdom, usher in a time of universal peace, make the lions sleep with the lambs, etc, he wasn’t who he said he was. Everyone abandons Jesus but his most loyal followers, and even they sulk and go back to fishing.
Time passes, and enter our friend Paul: he saw Jesus in a vision, so Jesus didn’t die after all! He gets together with the original apostles and revises the story of Jesus. Jesus did throw off a yoke, but that yoke was not Rome, but our sin. The kingdom he established was in heaven, not Jerusalem. His death, instead of a loss, was a gain: he died for us and he is now in heaven (I know, I saw the vision!) and we can all join him. All those other unfulfilled prophesies? Don’t worry, he’ll do all the rest when he returns!
Remember, those gospels and Acts were written nearly 50 years after Jesus died (and after most of Paul’s letters). So there was plenty of time to enter in a virgin birth, healings, miracles, and, of course, a resurrection (facets of many concurrent pagan religions). Go to http://www.snopes.com, and I’ll bet you could find a dozen urban legends you swore were true 5-10 years ago. Now, give an especially superstitious people 50 years, and viola!
But I’m told the Jews and/or Romans could’ve produced the body to quiet down those pesky Christians. Well, in the beginning, there weren’t a lot of Christians to quiet down. The gospels list maybe a few dozen people who saw Jesus return. What happened to the rest, like the multitudes who were fed 5000 loaves and fish, listened to his sermons, and cheered the Triumphal Entry? Once Jesus died, it was the end of the story for most of Jesus’ followers. It was hardly worth the Jews’ or Romans’ trouble to investigate the supernatural claims of so few. By the time Paul got the movement in full swing, there wouldn’t be much left of Jesus’ corpse to conclude anything.
Sometimes I get the “Lord, Liar, or Lunatic” tri-lemma. Jesus said he was Lord. Either he was wrong and knew it, which makes him a liar. Or he was wrong and didn’t know it, which makes him a lunatic. Since our lord and savior isn’t evil or a loony, he must be telling the truth. But the “urban legend” covers that, too: he was misquoted in the Bible, and did not claim to be Lord. Or the stories about him were made up, or embroidered with fictitious material by the early (or later) Christians.
Then I get told that the apostles were martyred and never recanted. No one would willingly be tortured and die to protect a lie. Only two people are martyred in the book of Acts: Stephen and James, but they were killed for blasphemy, not for believing Jesus rose from the dead. Since the Jews took blasphemy seriously, I doubt an 11th-hour recanting about Jesus would’ve saved them. The Christians who were persecuted by the Romans (thrown to the lions, etc), were not eyewitnesses, but later converts who believed the story (hmm, like an urban legend?). Other than that, there is zero historical evidence any other apostles (the only eye-witnesses of Jesus’ resurrection) were martyred. A popular story has Peter being crucified upside-down, but that is from a non-canonical (read: rejected by Christians) “Gnostic Gospel of Peter”.
