Sermon for Trinity 6. The Scripture readings are Exodus 20:1-17; Romans 6:1-11; and Matthew 5:17-26.

It is easy to think that legalism and antinomianism are opposite errors because legalism leads to a strict keeping of the Law and antinomianism leads to ignoring or belittling the Law. But these two errors are not opposites. The two share the same basic problem. Both legalism and antinomianism lower the standard of God’s Law.

Legalism lowers the standard by saying that the Law is doable, followable, attainable, and achievable. Antinomianism lowers the standard by saying that the Law doesn’t matter, that the Law doesn’t actually demand what it demands. And, again, we fall into both of these errors. Sometimes, it is in our attitude to the whole Law. Or, we might fall into legalism when it comes to certain Commandments and into antinomianism when it comes to other commandments.

Dear saints, when it comes to the Law, God doesn’t ever lower the standard. God doesn’t smile and wink at antinomians. God’s grace and mercy does not mean that God doesn’t care about sin. Yes, Jesus welcomed sinners, but not because He overlooked their sin. He welcomed them because He forgave their sin.

And your Pharisaic, legalistic good works and piety don’t impress God. God doesn’t watch your good works and respond. “Great job. I owe you for that.” No, His standards are higher than yours. Your righteousness must, it absolutely must, exceed the best of the best, or you will never enter the kingdom of heaven.

Where does this righteousness come from? It only comes through Christ. The righteous do not live by the Law; the righteous live by faith (Ro. 1:17). Romans 10:4 says, “Christ is the end of the law for righteousness to everyone who believes.”
