I think it would be interesting to have seen what Christians and others debated about Spirituality. for the first 300+ years when there was no New Testament. I read that Paul and Peter had their differences, but that too is a passed on idea. Spirituality was in people long before Jesus and the Torah existed. Archeologists have found statues,of many Mythical Gods centuries before the written word. Hammurabi was creditied with the first idea that there could only be one God and had a ten Commandment like idea.
