Really nice post. Often on FR, the number of “protestant” denominations is bandied about as if that disproves something. Your post lays out clearly that separation from cancer leads away from error and toward truth.
Instead of continually institutionalizing the accretion of errors, rites, continually adding new “authoritative traditions”, pagan practices, etc., it is far, far better to pursue Christ in purity and simplicity, and often this involves separation.
I will readily admit, some churches have split over silly issues - and I don’t believe they honored God. Most splits appear to be over theological issues.
