Tom Hicks posts on legalism and antinomianism:
There is a sense in which legalism is antinomian and antinomianism is legalistic. Legalism is antinomian because it invariably diminishes the absoluteness of the law and makes it easy enough to keep. Antinomianism is legalistic because though it throws off God’s law it makes every man a law unto himself and a slave to his own passions.
Well said. To find out what he’s talking about, and to find out what all those funny words mean, read the whole thing.
