Romans 10:17 So faith comes from hearing, and hearing through the word of Christ.
Not through the church.
Not through traditions.
Not through sacraments.
Through the word of Christ.
Matthew 22:29 Jesus replied, “You are in error because you do not know the Scriptures or the power of God.
Mark 12:24 Jesus replied, “Are you not in error because you do not know the Scriptures or the power of God?
Luke 24:27 And beginning with Moses and all the Prophets, he explained to them what was said in all the Scriptures concerning himself.
Luke 24:32They asked each other, “Were not our hearts burning within us while he talked with us on the road and opened the Scriptures to us?”
Luke 24:45Then he opened their minds so they could understand the Scriptures.
John 2:22After he was raised from the dead, his disciples recalled what he had said. Then they believed the scripture and the words that Jesus had spoken.
Acts 17:11Now the Berean Jews were of more noble character than those in Thessalonica, for they received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true.
2 Timothy 3:14-17 But as for you, continue in what you have learned and have become convinced of, because you know those from whom you learned it, and how from infancy you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work.
None of these verses teach that scripture alone is the rule of faith. They teach that the scripture is to be studied (Mt 22:29, Mk 12:24), that the Old Testament predicted the coming of Christ (Luke 24:27, John 2:22), that Christ explained the Old Testament to His Church (Luke 24:32,45), that the scruipture is to be used to verify theological claims (Acts 17:11, 2 Tim. 3:16). Finally, the entiore passage in 2 Tim. 3 teaches that the scripture is useful for the completion of the education of a "man of God", and is inspiured of God. None of that is under dispute. The Catholic Church would not have bothered to wruite theNew Testament if she did not consider the Hoyl Scripture very, very important.
The question is, where does the scripture teach that the scripture alone -- without the teaching authority of the Church and without the historical Sacred Tradition -- constitutes the complete rule of faith? Nowhere. But many times we read in the scripture that the entirety of the Word of Christ is equally important (your first "prooftext", Rom. 10:17), that the tradition is equally important (2 Thessalonians 2:14, 2 Timothy 3:14), that the Church will receive instruction from the Holy Ghost at all times (John 14:16, John 14:26), that the Church and not the reference to the scripture is to dispose of all disputes (Matthew 18:19).
A Christian man is not ruled by the Scripture alone but rather by "every word that proceedeth from the mouth of God".
