One must therefore portray the meaning of the sacred writings in a threefold way upon one's own soul, so that the simple person may be edified by what we may call the flesh of the scripture, this name being given to the obvious interpretation; while the one who has made some progress may be edified by its soul, as it were; and the one who is perfect and like those mentioned by the apostle: "We speak wisdom among the perfect; yet a wisdom not of this world, nor of the rulers of this world, which are coming to nought; but we speak God's wisdom in a mystery, even the wisdom that has been hidden, which God foreordained before the world unto our glory" (1 Cor. 2:6-7)--this one may be edified by the spiritual law, which has "a shadow of the good things to come" (cf. Rom. 7:14). For just as the human being consists of body, soul and spirit, so in the same way does the scripture, which has been prepared by God to be given for humanity's salvation.
Origen
