How misused: Though not explicitly quoted, the claim that 'No authentic Catholic teaching ever goes against Scripture' inherently misuses the Protestant understanding of 2 Timothy 3:16-17. Protestants often cite this passage to affirm Scripture's *sufficiency* (God-breathed, profitable for teaching, reproof, correction, and training in righteousness), arguing it equips believers for *every* good work, negating the need for extra-biblical traditions as co-equal authorities for doctrine and practice. ByzantineBro's stance implicitly interprets this passage as affirming Scripture's *inspiration* and *usefulness* but denies its *sole formal sufficiency* for all matters of faith and practice, asserting a continued reliance on tradition.
Scripture's answer: 2 Timothy 3:16-17 states 'All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work.' The Greek word 'ἀρτίος' (artios) means 'complete, sufficient, fully qualified.' This passage, within its immediate context (2 Tim 3:14-15 pointing to Timothy's upbringing in the sacred Scriptures), strongly supports the doctrine of Sola Scriptura by affirming Scripture's unique divine origin and its comprehensive sufficiency to equip believers for all aspects of Christian life and doctrine, without requiring external, equally authoritative traditions for completeness. The passage does not deny the existence of tradition, but it elevates Scripture as the sole divinely inspired and formally sufficient rule of faith.
