Let us look well to our own hearts. We live in a day when false doctrines about Christ’s death abound on every side. Let us see that Christ crucified is really the foundation of our own hopes, and that Christ’s atoning death for sin is indeed the whole life of our souls. Let us beware of adding to Christ’s sacrifice on the cross, as the Roman Catholic does. Its value was infinite and it allows no addition.
Let us beware of taking away from Christ’s sacrifice, as the Socinian (denial of Christ’s divinity) does. To suppose that the Son of God only died to leave us an example of self-denial, is to contradict a hundred plain texts of Scripture. Let us walk in the old paths. Let us say with Paul, “God forbid that I should glory, save in the cross of our Lord Jesus Christ.” (Gal. 6:14)
