There has been great attention given by scholars at the differences of what the apostle Paul taught, and what Jude, the brother of Jesus taught. Scholars point out to scripture where Paul mentions faith in Christ as being the only way to salvation, while they point out that Jude made mention of works. One thing you can almost always count on scholars on Christianity having- a lack of wisdom.
While it is true that there was a lot of dissension in the early Christian church that pitted faith in Christ against works, only those who fail at the ability to think can use Paul vs Jude as an example. There were many early Christian Jews whose mission in life was to turn Gentile Christians into Jewish Christians by focusing on the Law as a way to salvation. They ignored that God said there will be a new covenant that will come (Jeremiah 31:31-33). There is no question Paul fought hard at making sure that people knew that salvation can only come through faith that Jesus was the Messiah, which was the new covenant. He wrote about this in his epistles many times. What too many scholars void of faith or wisdom ignore is that Paul also made sure to let the people know to obey the Law. Paul wrote that works, which meant obeying the Law, would not bring salvation, but not obeying the Law made void salvation through faith. If one becomes a Christian but doesn’t change their sinful ways, then their conversion is for nothing. There are too many examples to list here where Paul made mention of sin, and pointed out people doing things contrary to the Law that should even be excommunicated. He chastized the Corinthians for not doing so (1st Cor. 5:1-13). Continuing in the next chapter, Paul wrote (1st Cor. 6:9-10) “Know you not that the unrighteous shall not inherit the kingdom of God? BE NOT DECEIVED: neither fornicators, nor idolators, nor adulterers, nor men who are effeminate, nor homosexuals,” “Nor thieves, nor covetous, nor drunkards, nor abusers, nor extortionists shall inherit the kingdom of God.” Do you think Paul was referring this to nonbelievers? Of course not.
Jesus said that after He returns, there will be many who are condemned that will say they accepted Him as the Christ, but that He didn’t accept them (Matthew 7:21-23). How does this happen? Did any of these so-called experts ask themselves “Was Paul unaware that Jesus said this?” I am quite certain that Paul knew what Jesus said considering Paul had hands laid on him, transferring wisdom about the Christ and scriptures to him from other apostles. Paul was well versed in the Gospel, and did great work to spread the Gospel. He suffered greatly doing so. Paul obviously knew what Jesus said.
Jude never said that salvation comes through works, but did say salvation is kept through works. Paul said salvation comes through faith, but you better obey the Law. Are these mutually exclusive, or are these in concert? One does not exclude the other at all, but then again I am no scholar.
