1. Ye already well know, dearest brethren, that a “Song of Degrees,” is a song of our ascent: and that this ascent is not effected by the feet of the body, but by the affections of the heart. This we have repeatedly reminded you of: and we need not repeat it too often, that there may be room for saying what hath not yet been said. This Psalm, therefore, which ye have now heard sung for you, is inscribed, “A Song of Degrees.” This is its title. They sing therefore while ascending: and sometimes as it were one man singeth, sometimes as it were many; because many are one, since Christ is One, and in Christ the members of Christ constitute one with Christ, and the Head of all these members is in heaven. But although the body toileth on earth, it is not cut off from its Head; for the Head looketh down from above, and regardeth the body. …Whether therefore one or many sing; many men are one man, because it is unity; and Christ, as we have said, is One, and all Christians are members of Christ.
