Which makes the church supreme, a man made doctrine, as Rome has presumed to infallibly declare she is and will be perpetually infallible whenever she speaks in accordance with her infallibly defined (scope and subject-based) formula, which renders her declaration that she is infallible, to be infallible, as well as all else she accordingly declares.
Thus tradition is only what she decrees it is (significantly differing even with the tradition-based Byzantine rite), and the only interpretation of Scripture that has any authority is hers.

Like Luther's novel doctrine of "the Bible alone," which is not biblical or part of Apostolic Tradition.
So Luther believed only the Bible could be used in knowing God's will, or do you want to provide a valid definition rather than the typical RC strawman? Do you deny even the supremacy of Scripture as the standard for obedience and establishing truth claims?
Can you prove that what was referred to in 2 Thessalonians 2:15 were things such as the assumption of Mary, and were not written down as was the norm for any revelation called the "word of God/the Lord," and that historical descent assures successors have the same level of veracity as the apostles? Be back later.
That's what sola scriptura is right?
