What dogma was previously anathematized by the Catholic Church as a whole ,but has since been codified?
Infallibility only rests in the Church on a universal level.
Actually, Protestants use a corrupted version of the Old Testament that they borrowed from the Jews.
Critical studies show that the Septuagint is far more accurate than the Textus Receptus used by the King James Bible.
I invite you to see what the ancients had to say about the Book of Romans 1,000 years before there was such a thing as Protestantism.
