By virtue of its divinely-appointed authority (Matt. 16:19; 18:18), the Catholic Church determined the canon of Scripture (what books belong in the Bible) at the end of the fourth century. We therefore believe in the Scriptures on the authority of the Catholic Church. After all, nothing in Scripture tells us what Scriptures are inspired, what books belong in the Bible, or that Scripture is the final authority on questions concerning the Christian faith. Instead, the Bible says that the Church, not the Scriptures, is the pinnacle and foundation of the truth (1 Tim. 3:15) and the final arbiter on questions of the Christian faith (Matt. 18:17). It is through the teaching authority and Apostolic Tradition (2 Thess. 2:15; 3:6; 1 Cor. 11:2) of this Church, who is guided by the Holy Spirit (John 14:16,26; 16:13), that we know of the divine inspiration of the Scriptures, and the manifold wisdom of God. (cf. Ephesians 3:10).
Non-Catholic christian churches also follow tradition. During the Reformation, the Protestants accepted the New Testament as defined by the Catholic Church in the late 4th century but excluded 7 OT books. What is that if not a man made tradition? According to the quote from the Book of Mark, you are suggesting that Protestants nullified the word of God. This is a good example of why private interpretation of the Bible is not condoned in the Bible Itself (2 Peter 1:20).
They certainly did NOT...Marty Luther based his German translation of the Scriptures on an entirely different set of manuscripts than those used by your church...
the Bible says that the Church, not the Scriptures, is the pinnacle and foundation of the truth (1 Tim. 3:15) and the final arbiter on questions of the Christian faith (Matt. 18:17).
There you go with your private interpretation that God warns about...The 'church is not the pillar and ground of the truth...God is...
Your church is permeated with unbelievers as all churches are...God is not foolish enough to trust anyone in your church or mine, with His infallible Truth...The Apostle Paul warned about your bunch in the Scriptures...
2Co 2:17 For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ.
The Scriptures that you so demean are the spoken words of God...God SPOKE the creation into existance...Your main weapon against the Devil are the spoken/written words of God...The writing that tells us that your religion is NOT the religion of God is God's spoken/written words in the Scripture...It's no wonder you put your authority above the Scripture, God's spoken/written words...
It is through the teaching authority and Apostolic Tradition (2 Thess. 2:15; 3:6; 1 Cor. 11:2) of this Church, who is guided by the Holy Spirit (John 14:16,26; 16:13), that we know of the divine inspiration of the Scriptures, and the manifold wisdom of God.
What a bunch of phony baloney
Here's one of the verses you cite as proof of that statement...
Joh 14:26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
Jesus never said anything to any of your man appointed popes...They weren't there...
The Holy Sjpirit was to provide perfect memory to the Apostles so when they authored the Scriptures, they were writing exactly what Jesus had said...There is nothing in that verse or the others you cite that refers to your religion...
