Well it basically started in the garden of Eden and continued from there. We talked about the ten commandments, the nature of morality and where it comes from (me - the fact that we are human, him - God), the crucifixion, miracles, the origins of the bible, etc. His thesis was basically Jesus loves ME, and I need him to be a good person because the world has been cursed by sin. Also, a lot of argument over whether the bible was true - I recall trying to convince him that Harry Potter was real. And Santa. In retelling the story to someone, this was their favourite part

Him: uses Bible as evidence for argument

Me: Well men wrote the bible, God did not write the bible

He: Well they were inspired by God (emphatic, as was everything else he said)

Me: Well Stephen King in inspired too (then I had to explain who Stephen King was)

Me: J. K. Rowling had a dream and the story just came out of her. I mean even that idiot Stephanie Meyer saw Twilight in a dream, unfortunately for the rest of the world. Maybe God exists and they were inspired by God. Or maybe they had schizophrenia or personality disorder or a hearing problem. You can't know if they actually spoke to God.

Him: But I have a personal relationship with God

Me: Half the people on this bus probably have a personal relationship with something that you would argue doesn't exist - a delusion, another personality, Elvis. It doesn't mean I need to believe it, too.
