Contradiction with Matthew 5:17
Jesus said He came not to destroy the law but to fulfill it, implying continuity rather than changes implied in John 7:22.
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 Proverbs 30:5-6
Declares that God's words are pure and warns against adding to them, contrasting with the interpretation of Moses' changes mentioned in John 7:22.
Proverbs 30:5-6: Every word of God [is] pure: he [is] a shield unto them that put their trust in him. [pure: Heb. purified]
Paradox #1
Some people find a contradiction in how this verse talks about Moses giving the practice of circumcision, even though this practice originally started with Abraham, not Moses. So, it could seem a little inconsistent or confusing about who introduced circumcision in religious tradition.
