I rather thought that the question was…what are the fundamentals that all Christians agree on?
I guess the first question is, what makes someone a Christian?
Once you have defined that, then you can look to see what else all of those people agree on.
The problem, of course, is three- fold:
1.what belief is it that, if held or not held, would cause a group that thinks it IS Christian to not be Christian,
2.who gets to decide what that belief would be, and
3.why in the name of all that is holy would anybody expect someone who thinks he is Christian to agree that he isn’t, because someone with whose doctrine he disagrees, says he’s not?
So I suggest that first, we find the ONE thing that everybody who claims to be Christian agrees on. Not '“the one thing I think they should agree on,” but the one thing everybody who claims to be Christian actually does agree on.
I suggested that the first thing, the one every Christian would have to agree on (because of the name…) would be that all Christians believe in the teachings of Jesus of Nazareth, called Christ.
I think all Christians would share this belief. Can you think of any that would not? Even the most extreme groups?
…but a belief in the teachings of Jesus of Nazareth isn’t exclusive to Christians, is it? Jews and Muslims both believe that He is a prophet, and taught some very important things. I know atheists and agnostics who think He taught some very valuable things. They don’t call themselves Christians as a result, though.
So I think item #2 would be…all Christians would claim to BE Christians; this is the belief they identify with.
They identify with Jesus the Christ as the most important Man (or leader/teacher/somebody) next only to God, if, that is, they don’t identify Him AS God. That is why they call themselves Christians, not “Jews” or Muslims or something else. It is the Christ that is central to their beliefs.
Can anyone think of anything else that every Christian would agree on–and I do mean EVERY Christian?
