Sola scriptura is the belief that only that which is found in the bible itself is truth, which is, in fact, contrary to what the bible says.
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.”
2 Thess. 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.”
1 Timothy 3:15:
“You may know how one ought to behave in the household of God, which is the church of the living God, the pillar and bulwark of the truth.”
These traditions are found in the Church Jesus Himself founded on Peter, the Rock. The one, true, holy, Catholic and apostolic church.
