Jesus constantly said, search the scriptures, you do err, no
Jesus said study the scriptures, you do err, not knowing the scriptures, in addition to saying it is written a lot - but did not once appeal to oral traditions - but He did speak against tradions of men.
And I guess you missed these scriptures:
2Ti 3:14 But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them;
2Ti 3:15 And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus.
2Ti 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
Scripture is for DOCTRINE, for REPROOF of wrong doctrine and for INSTRUCTION in righteousness and for knowledge of how to obtain SALVATION..
Scripture has the final word. Next:
2Ti 2:15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing THE WORD of truth.
We are told it’s our responsibility to study THE WORD and come to the truth.
Then in Acts 17 the Bereans are called noble for not taking the apostle Paul’s oral teaching for the truth until they searched THE SCRIPTURES to see if he was telling it correctly.
Scripture has the final authority, period..
Act 17:11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.
