The Catholic Church predates Scripture. Your analysis fails.
So, essentially having failed by argumentation to show the equality of tradition with Scripture, you fall back on tradition. That's called circular reasoning.
And it's not even factually correct, since what is now "the Catholic Church" evolved over a period of several centuries, only arriving at a more or less recognisable form after the time of Augustine.
Wrong. The Bible is God’s Word. Jesus is the Word in flesh and He predated the Church.
