When you look around at all of the denominations today, while some teach similar doctrines, most of them teach very diverse things. Of course, that’s the very reason that they are all in existence. If they taught the same thing, they would not be divided. Is that God’s design?
To the first-century congregation that was struggling with division, Paul made the singularity of his teaching very clear. Consider the collective impact of these inspired statements from the apostle’s pen: “…as I teach everywhere in every church…And so I ordain in all the churches… as in all the churches of the saints…as I have given orders to the churches of Galatia, so you must do also…” (1 Cor. 4:17; 7:17; 14:33; 16:1). Note carefully that what Paul taught in one church is what he taught in all churches. He did not change his message one iota in any place!
God’s design is for all people and all churches to “all speak the same thing, and that there be no divisions” (1 Cor. 1:10). What would the landscape of religion look like if we all did that?
