Francis Turretin, Institutes of Elenctic Theology, XII.12.22:
Nor is it absurd that in this way justification takes place by works and by faith – by the works of Christ and by our faith. And thus in sweet harmony the law and the gospel meet together in this covenant. The law is not administered without the gospel, nor the gospel without the law. So that it is as it were a legal-gospel and an evangelical-law; a gospel full of obedience and a law full of faith. So the gospel does not destroy the law, but establishes it (Rom. 3:31) by giving us Christ who perfectly fulfilled it. And the law is not against the gospel, since it refers and leads us to it as its end.
