The story introduces a new character, John the Baptist. He's a wild-eyed loony who lives out in the desert screaming "Repent! The End Is Near!" and must be the original model for the stereotype. He also screams insults at people who come to him, and demands for payment, along with lousy metaphors (e.g. god can produce children out of the stones--wtf?) but for some reason Jesus goes to see him. Jesus is all growed up now, his childhood only lasted a half a page.
They have a kindergarten moment; "You baptize me." "No you baptize me." It doesn't say what that's about; does he do this with everybody, or does Jesus give off holier-than-thou rays? Finally Jesus goes swimming, and when he comes out, the author demolishes our willing suspension of disbelief by having the sky open up and god give a product endorsement: "Me & Jesus--BFF!".
Oh, come on. You just put this in your story all matter-of-fact like it's the most normal thing in the world, nobody bats an eye? Even in fantasy writing you need to throw in an "Everybody was all 'WTF?' " for something like this.
Also, the spirit of god descended on him. Like a dove. Ewwww. At least it wasn't a sea gull.
