Why do gospel contradictions matter?

[abaris]

First off, I'm not a believer. But I constantly hear from fellow non believers that the gospels aren't reliable because they contain contradictions.

That's just one of the reasons why they aren't reliable. Multiple authors collecting hearsay and legends of a superstitious world. That's quite obvious, looking at the way the stuff was written.

And then of course there's the biblical equivalent of pink elephants and unicorns roaming the land at every gven moment.

But most of all, something supposed to be the law of a supreme being shouldn't contain any contradictions. It should be at least as reliable and straight as the Codex Hamurabi, which is quite literally written in stone.
