Paul does not contradict Christ at all,

Point 1 - Paul was also big on good works (Ephesians 2:10, Titus 2:14, 3:8 to mention a few), the works don't save they EVIDENCE salvation. So the result of salvation is you do good works and if you study what the WILL of the father is in John 6:40, it is that you come to Jesus to give you life.
Point 2- Law of Moses was never meant for Non-Jews and was not meant to be permanent, it pointed to someone to come . Jesus said He was fulfilling the law not abolishing, operative word here being FULFILL. His death and resurrection was in fact the fulfilment of that law. In Christ, Christians have fulfilled the law of Moses (All of Romans especially chapters 8 and 10). Once something is fulfilled, you are done with it aren't you? Because all the requirements have been satisfied.
Point 3- Paul also said no male or female in Christ and that husbands should love their wives as Christ the church. Paul's only thing was that women should not teach men in church, agree with it or not cool but does not contradict Jesus in any way. Paul also acknowledged Priscilla, a woman in ministry...big debate within Christianity on Egalitarianism v Complementarianism, we can disagree as brothers/sisters but not a big gospel issue either way
Point 4- There is this doctrine called the Trinity? Which both Paul and Jesus taught? Don't know if you have heard of it.

Point 5- Jesus taught both the love of God and the vengeance of God. Even in the verses you quoted there is no contradiction, you are to love your enemy and God takes vengeance on them. Something Paul says,
"Repay no one evil for evil. Have regard for good things in the sight of all men. If it is possible, as much as depends on you, live peaceably with all men. Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, “Vengeance is Mine, I will repay,” says the Lord."
(Romans 12:17-19)

Point 6- Again I struggle to see the contradiction here. Paul himself says Christ sent him to preach the gospel (1 Corinthians 1:17). Makes sense theology is front and centre, caring for the poor is secondary. Again, I highly doubt that taking care of the poor was Christ's priority, In Luke 4 He says He has been anointed to PREACH THE GOSPEL to the poor, not necessarily to "take care of them" in the sense you imply. So by preaching the gospel, Paul was prioritizing what Jesus prioritized.
Appreciate the article but I think there is a very warped understanding of what Christianity and Christ are really about.
