Ramsey is absolutely right. The law is not of faith. However, his conclusion that the Mosaic covenant is not works based is wrong. The Mosaic covenant is a law/works/meritorious covenant.
How then do we resolve this tension? John Owen did it by removing the Mosaic covenant from the covenant of grace. And he was right to do so.
This kind of honesty regarding the Westminster Confession and Covenant theology is all too rare in the attack on the so-called “Federal Vision.”
