What do you mean by "bible Christian?"
What I mean by Bible Christian is that I do not follow suit with denominations of Christianity. I go by what I interpret in the Bible.
With Xion intrigue, people tend to get a little lost in an idea that they are the only one's that 'know'. But I can give an exaple of how this may not, and probably isn't the case.
Lets assume, for the sake of argument, the Mothman is real. The conclusions that even a witness would draw from it may be inaccurate. Is this a demon or an angel? What is it's true purpose?
Therefore, Xy may have not have interpreted these entities as they truly are.
You can see this taking effect between Christians and Jews. Jews, for the most part, believe that the Adversary is charged by God to be so. Christians believe that he is a renegade angel.
But you see it between Christians and Muslims as well.
Muslims believe that Jesus was a prophet, Christians believe he is the King of all but God Himself. (unless of course, you hold the Trinity concept absolute)
Jews believe Jesus was a heretic.
All of them have their share of evidences.
There's a lot of irony as well as diversity, unfortunately.
And so being a Bible Christian is the best way to go, in my opinion, as there are already enough splitting concepts as it is.
