Rather then confuse the Catholic thread started by acmanco, I will start another on the real question.
The question is not which religious organization one belongs to or what sort of Christian organization one adheres to but rather if one calls him or herself a Christian what do you believe. Not what your church believes but what do you believe.
If you call yourself a Christian you are in some way making the claim that you are a follower of Jesus Christ.
So the question is Who Is He? What Is He? or What Was He? If you are a follower of Christ then what do you mean by that? Who is this one you claim to follow? Who is he to you?
I don't care if you consider yourself a Catholic, Protestant, Baptist, Lutheran or something else, if you claim to be Christian then who is this one you claim to follow?
