Biblical Text: Matthew 5:13-20, Isaiah 58:3-9
I don’t do these types of sermons that often. Most Sunday’s I try and proclaim the gospel. That proclamation of the cross of Jesus for you is the primary job. But occasionally the text seems to call for a catechetical or teaching sermon. In this case the question both the OT and the NT passages want us to ponder is: What is the purpose of the law? And this is a very important teaching of the church that we have simply lost today. This sermon looks at the two ways the church can lose the true purpose of the law: works righteousness (over-playing the role of the law) and antinomianism (underplaying the role of the law). It then turns to the catechism and confession’s three uses of the law with a specific meditation on almost a precursor to the formal law, a 0th use or a an expanded 1st use. Why expanded? Because none of the teachers of the church could imagine a people rejecting the natural law at such basic points.
