Here is a small list of the differences:
Paul said all the Law was fulfilled in one word (a Pharisaic teaching). Romans 13:8-9, Galatians 5:14. Yeshua said otherwise, Matthew 22:27-40, Mark 29-31.
Paul declared ALL things lawful, I Corinthians 6:12-14, Colossians 2:16. Yeshua said otherwise, Matthew 5:18, Luke 16:17, John 14:15.
Paul declared nothing unclean, Romans 14:14, I Timothy 4:1-5. Yeshua and James said otherwise, Acts 15:28-29, Revelation 2:14.
Paul claimed Christ abolished the Law, Romans 6:14, 7:4, Ephesians 2:15-16. Yeshua said otherwise, Matthew 5:17-20, 19:17, 28:20, Luke 16:17.
Paul claimed no one was justified by the Law, Romans 3:20, Galatians 3:11-12, 21. The scriptures say otherwise, II Samuel 22:21, Ezekiel 14:14, 20, Job 27: 29:14, Luke 1:5-6, James 2:20-22.
Paul claimed no man was justified by works of the Law, Galatians 2:16, 21. Yeshua and James said otherwise, Matthew 16:27, James 2:20-22.
Paul claimed the Law was veiled (too hard to understand), II Corinthians 3:12-16. Moses said otherwise, Deuteronomy 30: 10-14. John tells us the law is not burdensome, I John 1:53.
Paul called Yahwehs Law a curse, Galatians 3:13. (Galatians Chapter 3 and Romans Chapter 3 detail Pauls attack on the Law). Yeshua instructed us to keep the Law,Matthew 19:17. He came to fulfill the Law, not destroy it, Matthew 5:17-18. The Law was a blessing, Deuteronomy 7:11-13, 11:26-27, 30:19-20.
Paul referred to the Law as the ministry of death, II Corinthians 3:7. Moses said otherwise, Deuteronomy 4:40, 5:29, 6:24-25, 30:15-20.
Paul declared he sinned because of the Law (this passage is really a piece of work), Romans 7:7-13. James told us thats not so, James 1:13-14.
Paul speaks against questions he considers foolish, and genealogies, Titus 3:9. Since genealogies are immensely important to Adams seed and Satans seed in the old and renewed covenants, one must wonder why Paul tells Titus to avoid them.
*****
Paul claimed to be blameless (sinless) in the Law, Philippians 3:4-6.
Paul devalued the Sabbath, Romans 14:5-6.
