Origen

“ For as the different chords of the psalter or the lyre, each of which gives forth a certain sound of its own which seems unlike the sound of another chord, are thought by a man who is not musical and ignorant of the principle of musical harmony, to be inharmonious, because of the dissimilarity of the sounds, so those who are not skilled in hearing the harmony of God in the sacred Scriptures think that the Old is not in harmony with the New, or the Prophets with the Law, or the Gospels with one another, or the Apostle with the Gospel, or with himself, or with the other Apostles. ”

“ You see, then, that he is in the third place a peacemaker, who sees in accordance with the Scripture the peace of it all, and implants this peace in those who rightly seek and make nice distinctions in a genuine spirit. ”
