What IS good, and how do we determine it?

Note how the Christians can't even agree on their own story.

No, he is correct. I just did a poor job of referring to the trinity.

Fair enough. However, other Christians on here have given varying accounts of the trinity (Drich, for example, believes the word 'god' is a title, and that Jesus was, indeed, a completely separate entity from the father god entity), so my larger point still remains.

These kinds of fundamental differences on the basics of your religion is why there are over 40,000 sects of Christianity alone, and one of the reasons why we scoff at the idea that any particular flavor is actually the right one. That there is so much difference in opinion on how the trinity works, how god judges (good works more important than belief and obedience?), the nature of hell, etc. really only highlights how vague the source material actually is.
