“I dont think you have the Traditions to say such!”
Consider the following...
“...Thus you nullify the word of God by your tradition that you have handed down...”
Jesus, Mark 7:13
1 Cor 11:2 - hold fast to traditions I handed on to you
2 Thess 2:15 - hold fast to traditions, whether oral or by letter
2 Thess 3:6 - shun those acting not according to tradition
Jn 21:25 - And there are also many other things which Jesus did, which if they were written in detail, I suppose that even the world itself would not contain the books that would be written.
Mk 13:31 - heaven & earth shall pass away, but my word won't
Acts 20;35 - Paul records a saying of Jesus not found in gospels
2Tim 1:13 - follow my sound words; guard the truth
2Tim2:2 - what you heard entrust to faithful men
2Pet 1:20 - no prophecy is a matter of private interpretation
2Pet 3:15-16 - Paul's letters can be difficult to grasp & interpret
1Pet 1:25 - God's eternal word = word preached to you
Rom 10:17 - faith come from what is heard
1Cor 15:1-2 - being saved if you hold fast to the word I preached
Mk 16:15 - go to the whole world, proclaim gospel to every creature
Mt 23:2-3 - chair of Moses; observe whatever they tell you
...Thus you nullify the word of God by your tradition that you have handed down...
Jesus, Mark 7:13
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).
