Contradiction with Romans 14:5
This verse emphasizes individual conviction in moral decisions, while 1 Corinthians 10:29 focuses on considering the conscience of others.
Romans 14:5: One man esteemeth one day above another: another esteemeth every day [alike]. Let every man be fully persuaded in his own mind. [fully persuaded: or, fully assured]
Contradiction with Romans 14:14
This verse claims nothing is unclean in itself, opposing 1 Corinthians 10:29, which considers the perception of others regarding what is not inherently wrong.
Romans 14:14: I know, and am persuaded by the Lord Jesus, that [there is] nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him [it is] unclean. [unclean: Gr. common]
Contradiction with Galatians 5:13
Encourages using freedom responsibly, which may contrast with setting aside one's liberty in consideration of another's conscience as mentioned in 1 Corinthians 10:29.
Galatians 5:13: For, brethren, ye have been called unto liberty; only [use] not liberty for an occasion to the flesh, but by love serve one another.
Contradiction with Colossians 2:16
Suggests not letting others judge on matters of eating or drinking, which is contrary to the caution towards others' conscience in 1 Corinthians 10:29.
Colossians 2:16: Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath [days]: [in meat...: or, for eating and drinking] [respect: or, part]
Contradiction with 1 Corinthians 8:9
Encourages limiting personal freedom for the sake of others, seemingly in line initially but contrasts through its greater emphasis on the freedom versus 1 Corinthians 10:29's focus on external perception.
1 Corinthians 8:9: But take heed lest by any means this liberty of yours become a stumblingblock to them that are weak. [liberty: or, power]
