The Musical Harmony of the Scriptures

For just as the different chords of the harp and zither, each of which produces a sound unique to it that seems not to be similar to the sound of the other, are thought to be out of accord on account of the dissemblance of sounds by the uncultured who do not know the principle of musical harmony, so also with those who do not know how to listen to the harmony of God in the sacred Scriptures. These think that the Old is inharmonious with the New, or the prophets with the law, or the gospels with themselves, the apostle with the gospel or himself or the [other] apostles. But the one who has learned the music of God…this one will produce the sound of the music of God…For he knows that all Scripture is one harmonious instrument of God, producing one saving melody from different sounds for those who desire to learn, a melody that calms and hinders every action of the evil spirit. - Origen
