In last Sunday’s Gospel lesson we saw that there was a confrontation when Jesus went to the house of the ruler of the Pharisees for a meal on the Sabbath.  The conflict was entirely predictable because the Pharisees were persistently opposed to Jesus about issues that related to the Law of Moses and how it should be interpreted.

Last week Jesus asked the Pharisees about whether it was permitted to heal on the Sabbath. At another time when Jesus was in the synagogue on the Sabbath and a man with a withered hand was present, another group of Pharisees asked our Lord that same question. On that occasion Jesus answered that it was lawful to do good on the Sabbath and healed the man.  Then Matthew tells us, “But the Pharisees went out and conspired against him, how to destroy him.”

Questions about keeping the law continued as we learn in Matthew’s Gospel that the Pharisees and Scribes came to Jesus from Jerusalem and asked, “Why do your disciples break the tradition of the elders? For they do not wash their hands when they eat?” The Pharisees were attacking Jesus because his disciples were not following their interpretation of the law - what they called the “tradition of the elders.”

This conflict reached a crescendo during Holy Week. The Pharisees and the Sadducees – groups in Judaism who were opposed to each other – found a common enemy in Jesus. First the Pharisees plotted how to entangle Jesus in his words by asking him about whether it was lawful to pay taxes to Caesar. Then the Sadducees asked Jesus a question about the resurrection.

Next we learn in our text, “But when the Pharisees heard that he had silenced the Sadducees, they gathered together. And one of them, a lawyer, asked him a question to test him.” There is no doubt about what is happening here. The question by the Pharisee is not a request for information. It is an attempt to set a trap for Jesus. It is a question asked in the hopes that Jesus will say something that can be used against him.

At first glance, the question does not sound all that threatening. The Pharisee asked, “Teacher, which is the great commandment in the Law?” Judaism was indeed focused on the Law of Moses. We know that discussions about how to rank the commandments occurred. But still, it seems difficult to understand how the Pharisee thought this was going to generate an answer he could use against Jesus. In the Sermon on the Mount Christ had repeatedly stated, “You have heard it was said … but I say to you” as he corrected common interpretations of the law that were present in his day. So maybe the Pharisee hoped that Jesus would pop off with some kind “but I say to you” statement they could use against him.

If this was the intention of the Pharisee’s question, then he was greatly disappointed. Jesus answered by saying, “You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself. On these two commandments depend all the Law and the Prophets.”

Jesus identified Deuteronomy 6:5 as the great and first commandment. This was part of the Shema, the statement “Hear, O Israel: The Lord our God, the Lord is one” that was spoken by faithful Jews every day. And then our Lord added a second commandment, the statement from Leviticus 19 about loving the neighbor as yourself. The pairing of these two thoughts can be found elsewhere in Judaism and was hardly objectionable. But then Jesus added, “On these two commandments depend all the Law and the Prophets.”

First century Judaism was focused on the Law of Moses. How could it not be? After all, this was the law God had given to Israel at Mt Sinai when he brought them into his covenant. It was the law in which God told Israel how to live in the covenant with him. Israel knew that all of this was a matter of God’s grace. God had called Israel to be his people in fulfillment of his promise to Abraham, Isaac, and Jacob. He had rescued them from Egyptian slavery in the exodus. The gift of the law was a matter of God’s grace, just as the covenant of which it was a part. The law was a good thing. As the Psalm 119 says, “When I think on my ways I turn my feet to your testimonies; I hasten and do not delay to keep your commandments.”

The Jews never forgot that salvation was based on God’s grace. Only that made it possible. But over the centuries a shift occurred. There was an increasing confidence in a person’s spiritual abilities. There was an ongoing tendency to focus on the importance of what the person did in keeping the law and the role this had in being saved.  You can hear it in the rich young man’s question to Jesus, “Teacher, what good deed must I do to have eternal life?” And then there was the fact that although the law itself promised life, the history of Israel demonstrated that their continuing failure to keep the law brought only judgment.  

The Pharisees believed that the requirement to keep the law included their interpretation of the law and the things that it had added – the “tradition of the elders.” But in his answer Jesus casts all of that aside. For that matter he says nothing about circumcision, or food laws, or the Sabbath. He says it is very simple.  Love God with all that you are – the first table of the Ten Commandments. Love your neighbor as yourself – the second table of the Ten Commandments.  And the Lord says that this is what everything the Old Testament says to do is really all about: “On these two commandments depend all the Law and the Prophets.”

Jesus strips it down to the basics: Love God with all that you are. Love your neighbor as yourself. He says that’s really what it is all about. And in this we begin to recognize that if doing the law is going to be involved in any way with why we are saved, then we have a huge problem. For there are so many things that we put before God – our sports, our hobbies, our money and wealth, our need to be approved by our culture.  These are the things we often value most. And we find so many ways to put ourselves before our neighbor. I am going to focus on my needs and desires before my spouse, children, parents, or friends because I come first. After all, I deserve it.

St Paul tells us that in dealing with God, the way of the law – the way of doing – is a non-starter. It is because as fallen people sin is a power from which we cannot free ourselves. He told the Romans, “For we have already charged that all, both Jews and Greeks, are under sin.” And because this is so, the way of doing the law can only bring God’s curse and judgment. Paul told the Galatians, “For all who rely on works of the law are under a curse; for it is written, ‘Cursed be everyone who does not abide by all things written in the Book of the Law, and do them.’”

The Pharisee wanted to focus on the interpretation of the law. But then Jesus asked them a question that shifted the center of the conversation. He said, “What do you think about the Christ? Whose son is he?” The answer seemed simple. They said to him, “The son of David.” Everyone knew that the Christ – Messiah promised by God – would be a descendant of King David.

Then Jesus asked, “How is it then that David, in the Spirit, calls him Lord, saying, ‘The Lord said to my Lord, ‘Sit at my right hand, until I put your enemies under your feet’’? If then David calls him Lord, how is he his son?” Jesus quoted the first verse of Psalm 110. The available evidence indicates that the Jews of this time didn’t normally consider this to be a Scripture that spoke about the Messiah. Jesus was taking this text and interpreting it in a way they didn’t expect.  He was using it in his own way. Matthew tells us, “And no one was able to answer him a word, nor from that day did anyone dare to ask him any more questions.”

Jesus shifts the focus away from the Law of Moses to himself. In doing so, he shifts things from law to Gospel. And he points to himself as the fulfillment of all the Old Testament says – both the law and the prophets.

Jesus tells us that David was led by the Spirit of God to speak about the Christ as his Lord. Jesus is the son of David because Joseph took him to be his own son.  But Jesus is not only a man.  He is also the Son of God, the Creator of the universe. The angel said, “Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.” Conceived by the Holy Spirit and born of the virgin Mary, Jesus is the One whom David and all people must call Lord, for he is God himself.

The angel announced to Joseph that Jesus would save his people from their sins. He did this because all people, Jew and Gentile alike fail to keep God’s law. This law is God’s ordering of creation that expresses the will of the Creator for everyone. Paul said about the Gentiles – about you, “For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law. They show that the work of the law is written on their hearts.” It is this law that we all break as we sin against God.

But the Son of God entered this world and took on humanity in order to bear the wrath and judgment of God against your sin. As Isaiah said, “All we like sheep have gone astray; we have turned—every one—to his own way; and the Lord has laid on him the iniquity of us all.” God condemned your sin in Christ when he died on the cross.

Then God vindicated Jesus by raising him from the dead and defeating death. And what is more, he exalted Christ in the ascension as he was seated at the right hand of God in fulfillment of Psalm 110.  For as David wrote, “The Lord said to my Lord, Sit at my right hand, until I put your enemies under your feet.”

Paul told the Romans, “Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ.” Through faith in the crucified and risen Lord you are justified. You already know the verdict of the Last Day. You know that when you appear before the judgment seat of God he will declare you not guilty – free from sin and able to live in eternal fellowship with him.

Since you are already justified now by faith in Christ, it means that doing the law has nothing to do with your status before God. It simply can’t. So what does this mean for about how we view the law as we live in Christ?

Let us begin with the Law of Moses itself as we find it in the Old Testament. You will notice that Jesus never talks about circumcision and foods laws in the Gospels. He only talks about Sabbath keeping when attacked, and then only to say that things can be done on the Sabbath. In our text today he says that we are to love God with all that we are and love our neighbor as our selves and then concludes, “On these two commandments depend all the Law and the Prophets.” He says that this is what the Old Testament is really all about.

The specific details of the Law of Moses – its ceremonial aspect - was the command for God’s people until the coming of Christ. But now that Christ has come it no longer is. Christians are not in any way obligated to keep the Sabbath or follow the food laws. So enjoy that bratwurst if you want to. After all, we are going to have them at our upcoming Octoberfest.

Many Jews in Jesus’ day had fallen into the trap of thinking that their actions were part of the reason they were saved.  This is not surprising because it is temptation that always confronts fallen man. We understand the way of the law. You must do something to get something. It makes sense to us and that is the reason that every religion in the world apart from Christianity works in this way. This appeals to the old Adam because if I have some role to play, then I also get some of the credit.

The history of Christian theology demonstrates how enticing this is. It happened in the medieval period and continues to exist in Roman Catholic theology where God’s grace enables a person to do their part in that work that leads to salvation. Here it is not faith alone, but faith plus our works.

But it also continues to be found even in settings that confess faith alone. It happens when faith is defined as my choice – the thing I have done. Here the assurance of salvation is found in my choice – my act of believing. So by giving one’s testimony, or of going up for another altar call, or of being rebaptized the person recalls and renews the fact he really did it.

It happens when a sanctified life becomes the proof of salvation. How do I know I am a Christian and am saved? It is because of what I do – the holy ways in which I live. The source of assurance then is what I do, and so the true focus of the Christian seeking salvation becomes one of works.

Christ does not point us to the law. He points us to himself, for he alone is the source of forgiveness and life. He is the One who gave us new life as his Spirit was at work in baptism. He has called you to faith. And he continues to sustain that faith through his Means of Grace. He draws you to his Word and his Sacraments for through these means he gives forgiveness and nourishes faith by the work of the Spirit.

The apostle Paul told the Galatians, “For in Christ Jesus neither circumcision nor uncircumcision counts for anything, but only faith working through love.” Faith acts in love, because that’s what faith does. It is the fruit of the Spirit. It loves and cares for the neighbor in all the vocations where God places me – for my spouse, child, parent, congregation member, and friend.

Faith seeks to love God with all that we are. It seeks to love the neighbor as oneself. It does so because we are in Christ.  Or as Paul told the Galatians, “I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.”
