All it takes is a single, innocent lapse in hubris for the thought, “My theology could be wrong”, to creep in. Absolute disaster ensues when asking which others may be right. And hearing the reasons for each variant of Christianity only makes things worse; for you have gained understanding. But the utter gaffe comes next, realizing that belief has been made the center of Christianity, of salvation, of atonement.
Suddenly, as much as it pains but still for the lapse in hubris and in light of a vaporous centrality through understanding, a solution comes to mind! What if we find center by saying what is fundamental to Christianity is what all Christians agree on?
Three things become apparent. First is that all Christians believe Christ atones. Second is that no Christian collectively agrees on what atonement really means, because no Christian can agree on exactly what we’re being saved from, what divider between God and man Christ has removed, or how Christ atones in any case. These two things cancel each other out, leaving only a final agreement; the only possible thing which remains to call “fundamental” or “central” to Christianity is … well … to follow Jesus as exemplar in being human, to do as he did.
In a final but thankfully fleeting moment of lucidity, you realize all other Christian beliefs are only central to tradition and community.
But that was all a fleeting lapse, thank God. Of course everyone else is wrong about Jesus but me! What was I thinking after all! Silly me.
