“...holding Scripture as the standard for Truth...results in being opposed to many things in Roman Catholicism.”
“...Roman Catholicism...holds itself as the elite and only one True Church.”
So would you say that that which defines an “elite and only one True Church” is its “holding scripture as the standard for truth”?
Yeah. I don’t see how that definition has ever caused sectarian splits at all. Ever. O.o
Christianity was a split itself, while under both Sola Scriptura (or even Sola Prima) and Sola Ecclesia, that of Catholicism and major cults, you also have sects and schisms.
