“To know history is also to become Catholic.”
I know and have read history and do not believe what you wrote is true. Neither is it the focus of this thread.
I’ll pass and let the thread continue on topic.
Protestants have as their sole rule of faith the written Word of God, which we find in Sacred Scripture. The Catholic Church has as its sole rule of faith, the entire Word of God, as it is found in Sacred Scripture and Sacred Tradition.
All of the Word of God was at one time passed on orally...Sacred Tradition. Eventually, some of Sacred Tradition was written down...this became Sacred Scripture, which is written tradition. However, Scripture itself tells us that not all of the things that Jesus said and did were written down. And listen to what Paul says about “tradition”:
2 Thes 2:15, “So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.” Traditions! Traditions taught by word of mouth, in other words, oral tradition, and traditions taught by letter. Traditions which they are being told to “stand firm and hold to”. Sacred Scripture and
1 Cor 11:2, “I commend you because you remember me in everything and maintain the traditions even as I have delivered them to you.” The Corinthians are being commended by Paul because they maintain the traditions that he passed on to them. Sacred Scripture and Sacred Tradition.
2 Tim 2:2: “and what you have heard from me before many witnesses entrust to faithful men who will be able to teach others also.” What we have here in 2 Timothy is an instance, in Scripture, of Paul commanding the passing on of oral tradition.
1 Thes 2:13, “And we also thank God constantly for this, that when you received the Word of God which you heard from us, you accepted it not as the word of men but as what it really is, the Word of God, which is at work in you believers.” So, they received as the Word of God that which they heard, not simply that which they read in Scripture.
In other words, the Bible clearly supports the Catholic Church’s teaching that the Word of God is contained in both Sacred Scripture and Sacred Tradition.
