It's all right there in the canonical gospels. Jesus appears to a couple of the boyz on the road to Emmaus. They don't recognize him, and they walk along having an extensive discussion of the Hebrew scriptures and whatnot, then they reach an inn, and when he starts to break bread, they suddenly can tell it's him, and he teleports away. Mary Magdalene sees him in the Gospel of John, but she thinks he's the gardener. Obviously, in both cases he could not have appeared in Blood-n-Guts mode as he would have looked fresh from the crucifixion, with flesh hanging from his body in ribbons, bloody holes from the Crown O' Thorns on his head, etc.. When he appears to Thomas, he still seems to be cleaned up a bit, as everyone isn't going, "ERMAGHERD, SCARY BLOODY ZOMBIE JESUS!" but this time he does have wounds for Thomas to stick his fingers into.
