You do understand the meaning of sola scriptura don’t you? It means THE BIBLE ALONE. There is no Church Authority because that would simply lead back to Catholicism-- Real Catholicism, not Catholicism in name only. You can’t just
invent
your own NEW CHURCH as a Church Authority, because that is just another incarnation of sola scriptura, albeit an elaborate (and much more deceptive) one. CHURCH AUTHORITY, means returning back to THE CHURCH, THE CATHOLIC CHURCH, because that is were the Apostolic Authority resides. You can’t just
invest your imaginary church with Church Authority since NO ONE in your Church HAS THAT AUTHORITY to begin with. You MUST have Apostolic Authority. It is the ONLY Church authority. It is THE ONLY Authority recognized BY THE BIBLE! Unfortunately, THE ONE AND ONLY CATHOLIC CHURCH, which has apostolic authority, does not recognize any apostolic authority outside of Orthodox or Catholic Churches. Why? Because all other churches are UNBIBLICAL! ALL Protestant churches have cut themselves off from THE CHURCH. It is the one very REAL REALITY of Protestantism.
I think I provided the writings of the confessions prior. The “alone” in Bible Alone is simply the statement that only scripture is the final norm to hold teachings and doctrines accountable. Now, who makes teachings and doctrines? The Church. Sola scriptura is a practice of the Church, not individual interpretation.
It’s rather strange that Anglo Catholics consider themselves a true branch of Catholicism too, along with Orthodox and Roman Catholics. Yet no where do they have a branch for Lutheranism (of any kind) since Lutheranism is Protestant especially to other Protestants. Nothing is MORE Protestant than Lutheranism!
