The legalist and the antinomian share the premise that there is something in God’s Word that is dangerous to a Christian’s salvation. For the legalist it is the Gospel. For the antinomian it is the Law.
Nothing in God’s Word is dangerous to a Christian’s salvation.
An antinomian holds that under the gospel dispensation of grace the moral law is of no use or obligation because faith alone is necessary to salvation. This makes the Law of no use.
A legalist believes religiously following the law – like the Scribes and the Pharisees – is how one pleased God, and that the Gospel is of no use.
Lutherans reject both positions an adhere to the doctrine of “Law and Gospel.”
