Contradiction with Matthew 5:17-18
These verses suggest that Jesus did not come to abolish the law but to fulfill it, implying the law is still relevant, which could contradict the view in Isaiah 8:20 that solely emphasizes adherence to "the law and the testimony."
Matthew 5:17-18: Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Contradiction with Romans 10:4
This verse states that Christ is the end of the law for righteousness, which contradicts Isaiah 8:20 by suggesting that faith in Christ replaces adherence to the law.
Romans 10:4: For Christ [is] the end of the law for righteousness to every one that believeth.
Contradiction with Galatians 3:24-25
It states that the law was our guardian until Christ came and that now we are no longer under a guardian, suggesting a shift from the law mentioned in Isaiah 8:20.
Galatians 3:24-25: Wherefore the law was our schoolmaster [to bring us] unto Christ, that we might be justified by faith.
Contradiction with Hebrews 8:13
This verse indicates that by establishing a new covenant, the old one is obsolete, contradicting Isaiah 8:20, which emphasizes sticking to the law and testimony.
Hebrews 8:13: In that he saith, A new [covenant], he hath made the first old. Now that which decayeth and waxeth old [is] ready to vanish away.
Paradox #1
Isaiah 8:20 emphasizes adhering to the teachings and guidance of God, implying that any message not aligning with divine truth lacks value. A potential theological issue could be that this strict adherence might conflict with interpretations or teachings within different parts of the Bible or among various religious traditions that emphasize different aspects or understandings of God's word, potentially leading to disagreements about what constitutes valid spiritual authority or truth.
Paradox #2
Some people argue that there is a contradiction because this verse emphasizes sticking to the teachings of God and not other influences, but there are different interpretations and translations within the Bible itself. This can lead to debates about which specific teachings or interpretations are the correct ones to follow, causing confusion among various Christian groups.
