I have been contemplating the nature of Christian denominationalism, and it seems to me there are better ways to handle disagreements over doctrine and theology.
Before jumping to label someone a “heretic,” let us remember that even the fathers of the faith had disagreements over fundamental issues. Peter and Paul almost came to blows (probably more than once). How did they deal with this stuff?
They got together at a little meeting we now call the Jerusalem Council and decided issues that effect the Gentile church still today. Not only are the results of that meeting memorialized in scripture, so is the fight.
So, it’s okay to fight over doctrine, theology, how to worship, alcohol or juice, or the color of the carpeting, but we should come together, reach an acceptable resolution, and proceed accordingly.
I think God would honor the results.
