Contradiction with Matthew 5:17
This verse states that Jesus came not to abolish the law but to fulfill it, which could contradict the idea of removing the old leaven (symbolizing old laws or practices) in 1 Corinthians 5:7.
Matthew 5:17: 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 6:14
This verse emphasizes living under grace rather than the law, which might contrast with the notion in 1 Corinthians 5:7 of purging old leaven connected with old practices.
Romans 6:14: For sin shall not have dominion over you: for ye are not under the law, but under grace.
Contradiction with Hebrews 10:1
This verse discusses the law as a shadow of good things to come, suggesting continuity rather than the purging mentioned in 1 Corinthians 5:7.
Hebrews 10:1: For the law having a shadow of good things to come, [and] not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
Contradiction with Matthew 23:23
Jesus criticizes neglecting the weightier matters of the law, which may contradict the emphasis on removing the old leaven in 1 Corinthians 5:7, if seen as discarding elements of the law.
Matthew 23:23: Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier [matters] of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone. [anise: Gr. dill]
Contradiction with Galatians 5:3
This verse speaks to the obligation of keeping the whole law if one part is kept, potentially contradicting the idea in 1 Corinthians 5:7 of purging parts of the old leaven.
Galatians 5:3: For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
