Contradiction with Matthew 5:17
This verse, where Jesus states He came to fulfill the law, not abolish it, suggests a focus on fulfilling the spirit, not necessarily the detailed observance implied by Leviticus 19:37.
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 10:4
It suggests that Christ is the end of the law for righteousness, meaning that obeying the detailed laws, as instructed in Leviticus, is no longer necessary for righteousness.
Romans 10:4: For Christ [is] the end of the law for righteousness to every one that believeth.
Contradiction with Galatians 3:24-25
These verses indicate that the law was a guardian until Christ came, implying that strict adherence to the commandments like those in Leviticus 19:37 is not required after faith has come.
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 speaks of a new covenant, making the first one obsolete, suggesting a departure from the laws and statutes of the old covenant highlighted in Leviticus 19:37.
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.
