The "Sola Scriptura" itself refutes the idea that only the Bible is authoritative.
1TI 3:14 Although I hope to come to you soon, I am writing you these instructions so that, 15 if I am delayed, you will know how people ought to conduct themselves in God's household, which is the church of the living God, the pillar and foundation of the truth.
The church is the pillar and foundation of faith, NOT the Bible
And scripture supports the authority of oral tradition.
2Ti 2:1-2 You then, my son, be strong in the grace that is in Christ Jesus, and what you have heard from me before many witnesses entrust to faithful men who will be able to teach others also.
That is Paul's endorsement of oral tradition.
Also, the decisions of the 7 great councils (which gave us the Trinity the deity of Jesus and the Holy Spirit, the "dual" nature of Christ) were based on both scripture (and the NT canon was not settled when they began) and what the Church had taught everywhere and at all times from the beginning. (That includes oral tradition and the writings of the early church leaders.)
Totally agree!
That gives the student access to people who have been properly trained in the scriptures so that no one has to depend on his own guesswork and imagination. (Which many erroneously ascribe to the "leading of the Holy Spirit")
Here's some "sola scriptura" to consider:
Oral teaching references
Act 2:42 And they devoted themselves to the apostles' teaching (That would be oral teaching since no part of the NT had been written at that time.)
RO 10:17 Consequently, faith comes from hearing the message, and the message is heard through the word of Christ.
GAL 3:2 I would like to learn just one thing from you: Did you receive the Spirit by observing the law, or by believing what you heard? ……….. 5 Does God give you his Spirit and work miracles among you because you observe the law, or because you believe what you heard?
EPH 1:13 And you also were included in Christ when you heard the word of truth, the gospel of your salvation. Having believed, you were marked in him with a seal, the promised Holy Spirit,
EPH 6:19 Pray also for me, that whenever I open my mouth, words may be given me so that I will fearlessly make known the mystery of the gospel, 20 for which I am an ambassador in chains. Pray that I may declare it fearlessly, as I should.
PHP 4:9 Whatever you have learned or received or heard from me, or seen in me - put it into practice. And the God of peace will be with you.
COL 1:3 We always thank God, the Father of our Lord Jesus Christ, when we pray for you, 4 because we have heard of your faith in Christ Jesus and of the love you have for all the saints-- 5 the faith and love that spring from the hope that is stored up for you in heaven and that you have already heard about in the word of truth, the gospel 6 that has come to you. All over the world this gospel is bearing fruit and growing, just as it has been doing among you since the day you heard it and understood God's grace in all its truth
COL 1:22 … he has reconciled you by Christ's physical body through death to present you holy in his sight, without blemish and free from accusation-- 23 if you continue in your faith, established and firm, not moved from the hope held out in the gospel. This is the gospel that you heard and that has been proclaimed to every creature under heaven, and of which I, Paul, have become a servant.
1TH 2:13 And we also thank God continually because, when you received the word of God, which you heard from us, you accepted it not as the word of men, but as it actually is, the word of God, which is at work in you who believe.
1TH 4:1 Finally, brothers, we instructed you how to live in order to please God, as in fact you are living. Now we ask you and urge you in the Lord Jesus to do this more and more. 2 For you know what instructions we gave you by the authority of the Lord Jesus. (This is a reference to oral teaching.)
2TH 2:15 So then, brothers, stand firm and hold to the teachings we passed on to you, whether by word of mouth or by letter.
2TI 1:13 What you heard from me, keep as the pattern of sound teaching, with faith and love in Christ Jesus.
2TI 2:2 … the things you have heard me say in the presence of many witnesses entrust to reliable men who will also be qualified to teach others.
HEB 2:1 We must pay more careful attention, therefore, to what we have heard, so that we do not drift away. 2 For if the message spoken by angels was binding, and every violation and disobedience received its just punishment, 3 how shall we escape if we ignore such a great salvation? This salvation, which was first announced by the Lord, was confirmed to us by those who heard him.
JAS 1:22 Do not merely listen to the word, and so deceive yourselves. Do what it says. 23 Anyone who listens to the word but does not do what it says is like a man who looks at his face in a mirror 24 and, after looking at himself, goes away and immediately forgets what he looks like. 25 But the man who looks intently into the perfect law that gives freedom, and continues to do this, not forgetting what he has heard, but doing it--he will be blessed in what he does.
1JN 1:1 That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked at and our hands have touched--this we proclaim concerning the Word of life………..3 We proclaim to you what we have seen and heard, so that you also may have fellowship with us. And our fellowship is with the Father and with his Son, Jesus Christ.
1JN 1:5 This is the message we have heard from him and declare to you:
1JN 2:7 Dear friends, I am not writing you a new command but an old one, which you have had since the beginning. This old command is the message you have heard.
1JN 2:24 See that what you have heard from the beginning remains in you. If it does, you also will remain in the Son and in the Father.
1JN 3:11 This is the message you heard from the beginning:
1JN 4:3 but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world.
2JN 1: 6 And this is love: that we walk in obedience to his commands. As you have heard from the beginning, his command is that you walk in love.
