When did the gates of hell prevail against the Church, the pillar and foundation of truth, that wrote, canonized and preserved the Bible?
Where does your standard for judging the truth of doctrine come from?
From a logical perspective, at the very least, the Bible should claim to be the only standard by which truth should be judged. It doesn’t.
The standard that you have adopted, “the Bible alone,” is Luther’s alone. He had no authority to promulgate this novel teaching.
See if you can find a historical reference to Luther’s doctrine prior to his time, or in the Bible.
The church fell down once it adopted the Jesus is God doctrine and lost the real meaning of prayer. Roy Masters has indeed revived that “Be Still and know that I am God” of the bible. And the objective truth is revealed identically in all truth lovers as a conscience, or holy spirit. That is what instructed the authors of the bible.
