Sola Scriptura is a theological tenet that says Christian beliefs or views can only come from the Bible. This belief implies that if a Christian receives a revelation or esoteric knowledge from God on any religious subject, it cannot be valid unless it stacks up with Bible scripture.
I’m not so sure I agree with this opinion. The Bible didn’t get written down and canonized in its present form until many decades after Jesus’ crucifixion. But there were many early believers who were around before that, and they didn’t have the Bible, so they had to learn from oral tradition or private revelation from God about theological subjects.
If you believe in Sola Scriptura, how would you explain how people were Christians before the Bible was canonized? In my opinion, this seems to suggest that Sola Scriptura may not be the best theology.
This is a bit inaccurate. The cannon was reduced to include only 66 books, but the Septuagint was a rabbinical translation to Greek that was assembled for the Diaspora in the 3rd century BC, and included the books of the old testament and some apocryphal texts.
Some modern translations used the Septuagint as a source, because the text represents a Hebrew understanding of the Old Testament over 250 years before the birth of our Lord.
The Apostle Paul taught Christ to Jews reasoning from the Old Testament.
Jesus Himself said this about the written word (Old Testament scriptures):
39“You search the Scriptures because you think that in them you have eternal life; it is these that testify about Me;
John 5:39
Everything that pertains to Christ is found in the Old Testament including the gospel, but veiled in prophecy, law, Psalms, proverbs, and history. The New Testament was written as Epistles to the churches, letters to saints, and as accounts of Jesus' ministry during His incarnation and after His resurrection.
The Apostle Paul wrote his second epistle to Timothy, a leader in the first century church and said this:
14You, however, continue in the things you have learned and become convinced of, knowing from whom you have learned
them, 15and that from childhood you have known the sacred writings which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus.
16All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness;
17so that the man of God may be adequate, equipped for every good work.
2 Timothy 3:14-17
If you read the entire chapter, this instruction was addressing false teachings, abuses of the faith by thieves and liars that were taking advantage of unstable people.
There were already numerous heresies, false gospels, perversions of the truth, being taught by wicked men for personal gain while the Apostles were still alive.
The "canon" was described and sealed by early church patriarchs to protect the immature and carnal minded from being drawn away from the truth, our Lord Jesus the Christ.
Cults add to the written word for the benefit of the cult leaders, and all to enslave minds to their purposes.
Does God speak to our spirits to give us guidance?
Scripture says that He does, but He doesn't guide us to oppose His word (that would make Him schizophrenic. )
Does Satan and the unclean spirits speak to us to lead us away from the truth. Scripture says that he does and that the demons obey him.
If you can accept that the purpose of scripture is the revelation of God in the person of His Son, then the revelation is complete in Him.
Instructions for guidance in serving the body of Christ is an entirely different matter, but to be clear, the Holy Spirit glorifies our Lord, our Lord glorified His Father, and the Father glorified His Son.
Any voice that denies these basic truths opposes Christ and serves another.
