Contradiction with James 3:2
This verse suggests that if any man does not offend in word, he is a perfect man, implying it's possible to achieve perfection, contrary to the universal accountability implied in Matthew 12:36.
James 3:2: For in many things we offend all. If any man offend not in word, the same [is] a perfect man, [and] able also to bridle the whole body.
Contradiction with Colossians 4:6
Advises letting your speech be seasoned with grace, suggesting the potential for positive and blameless speech, contrasting with the focus on accountability for idle words in Matthew 12:36.
Colossians 4:6: Let your speech [be] alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.
Contradiction with Proverbs 10:19
States that with much speaking sin is not lacking, but one who restrains his lips is wise, suggesting wisdom can mitigate the fault of idle words, differing from the inevitable charge in Matthew 12:36.
Proverbs 10:19: In the multitude of words there wanteth not sin: but he that refraineth his lips [is] wise.
Contradiction with 1 Peter 4:8
Emphasizes love covering a multitude of sins, suggesting that love may mitigate or overlook idle words, unlike the strict accountability mentioned in Matthew 12:36.
1 Peter 4:8: And above all things have fervent charity among yourselves: for charity shall cover the multitude of sins. [shall: or, will]
Contradiction with Ecclesiastes 5:2
Advises to not be rash with words before God, promoting restraint over accountability for every idle word as suggested in Matthew 12:36.
Ecclesiastes 5:2: Be not rash with thy mouth, and let not thine heart be hasty to utter [any] thing before God: for God [is] in heaven, and thou upon earth: therefore let thy words be few. [thing: or, word]
Paradox #1
Some people might see a contradiction or inconsistency when comparing this verse to teachings about forgiveness and grace. If every idle word is judged, it might seem to conflict with the idea that believers are forgiven for their mistakes through faith. This could appear inconsistent with the concept of unconditional forgiveness.
