Magisterium vs Sola Scriptura

Magisterium is an interesting idea that is a source of confusion between Catholic and Protestant faiths. I say confusion because I think history shows Martin Luther was correct at the Diet of Worms (1521). Martin Luther argued that the Catholic Magisterium (the Pope and church councils) did not have ultimate authority over sacred scripture, declaring instead that Scripture is its own supreme interpreter and that church authorities could and did err. However in the New Testament, "pastor" and "elder" refer to the same office of church leadership. An elder (presbyteros) is the title of the office, while pastor (poimen, meaning "shepherd") describes the function. Both terms are used interchangeably with "overseer" (episkopos) to denote the spiritual leaders of a congregation. So we still have fallible people in charge. The idea of sola Scriptura is not to add or take away what that means and was understood from the first generation church. Most born-again Catholics and protestants agree with this today. (1 Timothy 3:1-7, Titus 1:5-9, 1 Peter 5:1-2, Acts 20:17,28)

Passages Catholics cite for Magisterial authority:

• Matthew 16:18-19 — Peter given the "keys of the kingdom" and power to "bind and loose"
• Matthew 18:18 — same binding/loosing authority extended to the apostles collectively
• Luke 10:16 — "whoever listens to you listens to me"
• John 16:13 — the Spirit will guide "you" (the apostles) "into all truth"
• Matthew 28:19-20 — the Great Commission, with Christ promising to be with the church's teaching mission "always"
• Acts 15 — the Council of Jerusalem resolves doctrinal dispute with binding authority ("it seemed good to the Holy Spirit and to us")
• 1 Timothy 3:15 — the church called "the pillar and bulwark of truth"
• 2 Thessalonians 2:15 — believers told to "hold to the traditions" taught "either by word of mouth or by letter"
• 2 Timothy 2:2 — Paul instructs Timothy to entrust apostolic teaching to faithful men who will teach others

Passages Luther and Protestants cite for sola scriptura:

• 2 Timothy 3:16-17 — "All Scripture is breathed out by God and profitable... that the man of God may be complete, equipped for every good work"
• Acts 17:11 — the Bereans praised for testing Paul's preaching against Scripture
• Isaiah 8:20 — "To the teaching and to the testimony!"
• Mark 7:8-9, 13 — Jesus condemns the Pharisees for "making void the word of God" through human tradition
• Galatians 1:8 — even an angel preaching a contrary gospel is "accursed"
• Deuteronomy 4:2; 12:32 and Revelation 22:18-19 — warnings against adding to or subtracting from God's word
• John 17:17 — "Sanctify them in the truth; your word is truth"

The core exegetical dispute is how to read 2 Timothy 3:16-17 and 1 Timothy 3:15 against each other: Protestants read "complete, equipped for every good work" as Scripture being materially sufficient on its own, while Catholics read "pillar and bulwark of truth" as implying Scripture needs a living, authoritative interpreter (the church) to function as intended, and point to 2 Thessalonians 2:15 as evidence apostolic teaching wasn't confined to what got written down. Neither side disputes the texts themselves — the disagreement is about what authority, if any, stands over their interpretation.
