Charles Hodge, great professor from Princeton Seminary in the 19th century, said: "After all, apart from the Bible, the best antidote to all these false theories of the person and work of Christ, is such a book as Doctor Schaff's 'Christ in Song.' The hymns contained in that volumne are of all ages and from all churches. They set forth Christ as truly God, as truly man, as one person, a the expiation for our sins, as our intercessor, savior, and king, as the supreme object of love, as the ultimate ground of confidence, as the all-sufficient portion of the soul. We want no better theology and no better religion than are set forth in these hymns. They were indicted by the Holy Spirit in the sense that the thoughts and feelings which they express, are due to his operations on the hearts of his people."
