While reading through the Gospels, I noticed that Jesus seemed to emphasize the importance of the Law and living a holy life. However, Paul essentially tells Christians to abandon the Law (because righteousness cannot be attained by it) and live by faith instead. Why is there this discrepancy between the teachings of Jesus and Paul and how are they reconciled?
Paul and the Law is one of the most complicated and most debated arguments in the Christian tradition.
In some cases it seems to sound as though Paul is saying the Law is wholly unnecessary in every respect and even harmful; in other places Paul sounds like he's saying the Law is good and must be obeyed.
Then, of course, there may be the debate as to what Paul means by "the Law" and if he means the same thing every time. Does Paul always mean the Torah or does he sometimes refer more generally to "Divine Law" and/or how do we navigate these?
Here's my perspective, and it is largely informed by the broad Christian tradition and Lutheran theology in particular:
Paul, with the conviction that he has been given a calling to preach Christ and the message of Christ (the Gospel) to the Gentiles is convinced that the Christian message and Christian vision is much bigger than it being a "Jewish thing". So largely the theological opponents he's facing are those who are saying that Christianity is fundamentally a "Jewish thing", i.e. to be a Christian one must become a Jew and participate in the Jewish Covenant and therefore become circumcised and fully Torah observant. In stark opposition Paul is convinced that God fully embraces and accepts the Gentiles as Gentiles.
God, through Jesus, has reached out and into the world and accepts both Jew and Gentile equally, and the Gentile can be a Gentile--uncircumcised, non-Torah observant and be a Christian, be a follower of Jesus, and reconciled to God.
That's crucial to Paul's theology, as Paul envisions Jesus' message and movement as uniting all disparate groups of people--Jews and Gentiles, circumcised and uncircumcised, civilized and barbarian, slaves and freemen, men and women (everyone)--into this new creation and kingdom which God is birthing into the world (i.e. the Church).
Because of this, Paul is adamant that Gentiles don't have to become Torah-observant in order to be part of this God movement, and goes to great lengths to argue that point and at times seems to speak with some level of exasperation and frustration (in Colossians, I believe, Paul in an outburst of frustration says of those who continue to insist that Gentiles have to be circumcised says, "They should just cut the whole thing off"). For Paul whether one has a bit of skin or not is, in what God has done and is doing through Jesus, is absolutely irrelevant. Not because what God did for the Jews, God's giving of Torah and circumcision to Israel was meaningless; but that this Jesus thing is much bigger and getting caught up in something like circumcision is totally missing the point.
But Paul is equally adamant that, because of the great universalization of the Jesus movement and vision, that Grace is what matters. That is, it's God's love and kindness extended toward the world through Jesus that is reconciling us, and that it has absolutely nothing to do with how good we act; God loves us unconditionally anyway, (e.g. "God demonstrates His love for us in that while we are yet sinners, Christ died for us." and "This is a trustworthy saying, Christ came to save sinners, and I am the chief of sinners").
That's fundamental here.
Now Paul is saying all this after the fact. It's being said in the wake of the Jesus Event. Thus Paul is iterating Jesus and the meaning of Jesus for the sake of other Christians and Christian communities.
The Gospels are the bare Jesus Event--what Jesus taught and did, the story of Jesus and the message of Jesus as it is. Paul's writings are to specific people and communities, that means the proper application of the Jesus Event, the story and message and teachings of Jesus for communities of disciples of Jesus.
Jesus' teachings are absolute. And Paul is not in contradiction to Jesus, nor do his teachings overwrite Jesus. If Paul and Jesus contradict, then the solution would be simple: Jesus is Lord, Paul is not. Jesus' teachings trump Paul every time without question.
However, we don't view there being a contradiction, but rather Paul as interpreting and applying Jesus for actual living and breathing communities of Christians living out the daily grind of having to exist and apply Jesus to their lives day in and day out. That's what Paul is doing.
When Paul "criticizes" the Law, it's for the purpose of his theology of mercy, of emphasizing God's full embrace of all people equally in Jesus against certain theological opponents.
Jesus, as teaching about the Law, is simply saying that we should be faithful and obedient to God. Paul speaks of the Law in similar ways in his writings as well.
The Law was never abolished, contrary to the thinking of some Christians, rather:
1) Torah was never given for non-Jews. It is part of God's unique Covenant that He made with the Children of Israel at Mt. Sinai.
2) Torah was never given for salvation as Christians understand salvation. That wasn't the reason God gave Israel the Torah, that's not why He gave the Jews the Torah.
So, again, when Paul talks about the Law not being for Gentiles or it's inability to save, this is what he's talking about. He is not saying it was abolished, or that it's bad (he says the opposite many times in his writings).
Jesus, again, is teaching people to grow up spiritually, and as such being obedient to God is far more than simply the written mitzvot of the Torah.
These things are not in opposition to one another, but are in harmony with each other.
