2. SUPERNATURAL BEAUTY.—Though we can quote no formal ecclesiastical definition to prove that sanctifying grace beautifies the soul, the fact is sufficiently certain from Revelation. If, as is quite generally held by Catholic exegetes, the Spouse of the Canticle typifies the human soul endowed with sanctifying grace, all the passages describing the beauty of that Spouse must be applicable to the souls of those whom Christ embraces with His tender love. The Fathers of the Church frequently extol the supernatural beauty of the soul in the state of grace. Ambrose calls it “a splendid painting made by God Himself;” Chrysostom compares it to “a statue of gold;” Cyril, to “a divine seal;” Basil, to “a shining light,” and so forth. St. Thomas says: “Divine grace beautifies [the soul] like light,”(1058) and the Roman Catechism declares: “Grace ... is a certain splendor and light that effaces all the stains of our souls and renders the souls themselves brighter and more beautiful.”(1059) In defining beauty as “the representation of an idea in a sensual form,” modern aesthetics has eliminated the spiritual element and in consequence is unable to appreciate the spiritual beauty of God and of the soul. Being composed of body and soul, man is naturally most impressed by beauty when it appears in a material guise. But this does not prove that there is no spiritual beauty, or that true beauty abides solely in matter. Some present-day writers strongly emphasize the need of realism as against an idealism which, they claim, is not truly human because it exalts the spiritual at the expense of the material. In its last conclusions this perverted realism harks back to the sophistry of Protagoras who held that “man is the measure of all things.”(1060) Idealism, on the other hand, is based on the true Platonic doctrine that God is the measure of all things.(1061) St. Augustine defines beauty as “unity in variety,” which is a correct definition, because it is adaptable to both the spiritual and the material order.(1062) Applying this definition we find that the soul is not only naturally beautiful by the substantial unity and simplicity which shines forth in the variety of its faculties and powers, but also supernaturally by virtue of sanctifying grace, which transfuses nature into a new unity with the supernatural,—at the same time producing a variety of theological and moral virtues and the seven gifts of the Holy Ghost, and thus creating a true work of art. Moreover, by enabling man to participate in the Divine Nature,(1063) grace produces in the soul a physical reflection of the uncreated beauty of God, a likeness of the creature with its Creator, which far transcends the natural likeness imprinted by creation. True, only God and the Elect in Heaven perceive and enjoy this celestial beauty; but we terrestrial pilgrims can, as it were, sense it from afar and indulge the hope that we may one day be privileged
