Okay, but you're talking about an entirely different doctrine now: Deification.
Regardless, I consider myself a Christian because I worship Jesus Christ. Every religious service or act I have ever participated in has been done in His name. The most significant doctrines I believe in were preached by Him.
I find the idea that because I don't believe in the Athanasian Creed I am therefore not a Christian to be absurd and impossible to support authoritatively. You are, of course, entitled to your own opinion on this matter.
