Does Paul’s command to “hold fast to the traditions” in 2 Thessalonians 2:15 prove that binding Christian doctrine can exist outside of Scripture?In this video, I examine the appeal to apostolic oral tradition and the assumption that the Church today possesses authoritative teachings handed down orally from the apostles. I argue that this assumption collapses once we ask a simple but unavoidable question: how would we know that a specific doctrine not found in Scripture actually goes back to the apostles?Christians do not deny that the apostles taught orally or that their teaching was authoritative. The issue is access. We no longer hear the apostles speak. What we do have is the inspired, written record of their teaching—the New Testament. Scripture is therefore not a rejection of apostolic authority, but the only surviving form of it.When doctrines such as image veneration, purgatory, indulgences, prayers to saints, or papal infallibility are defended on the basis of alleged oral tradition—despite contradicting the apostles’ written teaching—they become historically unverifiable and immune to correction. At that point, authority no longer rests on apostolic teaching, but on ecclesiastical assertion.Some respond by claiming that God guarantees the truth of the Church, appealing to texts like 1 Timothy 3:15. But the New Testament repeatedly warns that false teachers will arise within the Church itself, claiming authority while teaching what contradicts the apostles. If appeals to unverifiable oral tradition are allowed to override Scripture, there is no way to identify or correct such false teaching.In this video, I argue that Scripture alone provides the necessary and God-given standard by which apostolic teaching is preserved, tested, and safeguarded. Sola Scriptura is not a denial of tradition—it is the only protection against false tradition.#SolaScriptura #ApostolicTradition #2Thessalonians215 #BibleAuthority #ChurchAuthority #Catholicism #EasternOrthodoxy #ChristianApologetics #ReformedTheology
