Rick doesn't mention Christianity in his books, as it would only cause controversy and have no relevance to the story line. So that isn't particularly relevent to what Kronos300 is  trying to say. I'm pretty sure it's been said in the books that it's debatable who out of the big 3 s strongest. And of course Gaia is stronger than Zeus, just as Typhon was, because otherwise why would it take multiple gods/ gods and demigods to vanquish them?
