Well, you and I will have to differ there. The mottoes of the Reformation were Sola Scriptura, Solo Christo, Sole Fidele: “the Bible alone,” “Christ alone,” “Faith alone.”
In other words, our only authority is the Bible, our only Mediator is Christ, and we are saved by faith in Him alone, not by our own works, lest any man should boast.
One out of three ain't bad. Sola Scriptura and Sola fide are false traditions of men.
