THE CHURCH AND THE WORD OF GOD

Charles Hodge:

All her triumphs over sin and error have been effected by the word of God. So long as she uses this and relies on it alone, she goes on conquering; but when any thing else, be it reason, science, tradition, or the commandments of men, is allowed to take its place or to share its office, then the church, or the Christian, is at the mercy of the adversary. Hoc signo vinces—the apostle may be understood to say to every believer and to the whole church. (A Commentary on the Epistle to the Ephesians)
