THE ANGELS.--Each of the nine moving spheres is assigned to the care of one of the nine angelic orders: Angels, Archangels, Principalities; Powers, Virtues, Dominations; Thrones, Cherubim, Seraphim. And the character of the blessed spirits that appear to Dante in each heaven, and the subjects discussed, seem in almost every case to correspond more or less closely with the functions assigned by mystical theologians, especially Dionysius, St. Gregory and St. Bernard, to the special angelic order which presides over the sphere in question. There are two fundamental principles in the life of the soul: nature and grace. The one is represented in the _Paradiso_ by the astronomical order of the heavens and their influence upon individual disposition, furnishing man with a natural aptitude for the moral and intellectual virtues; the other by the bounty of Divine Grace, which reveals itself in the perfecting of the natural and the infusion of the supernatural virtues, whereby souls become assimilated to the angelic orders.[37] It is through these Angels (the name is applied generally to all, as well as to the lowest order) that God disposes the visible world; in the hands of the celestial intelligences the heavens are as hammers, to stamp the Divine ideas upon material creation and carry out the Divine plan in the government of the Universe (_cf._ _Par._ ii. 127-129). And, by means of the influence of the stars, these Angels have impressed certain men with their own characteristics; perhaps to fill up the vacant places in their ranks left by the fall of Lucifer’s followers, certainly to co-operate on earth in their work. Dante himself was born beneath the constellation of the Gemini, the glorious stars impregnated with the virtue of the Cherubim who rule the eighth sphere (_Par._ xxii. 112-123). The Cherubim represent the Divine Wisdom; their name signifies plenitude of knowledge. According to St. Bernard, they “draw from the very fountain of wisdom, the mouth of the Most High, and pour out the streams of knowledge upon all His citizens.” Their special prerogatives are fullness of Divine light, and contemplation of the beauty of the Divine order of things; they see most into the profound mysteries of the hidden things of God, and spread the knowledge of Him upon all beneath them. By their inspiration Dante co-operated in this cherubical work by writing the _Divina Commedia_. The Seraphim especially represent the Divine Love. No soul appears in the ninth heaven which they guide and in which the angelic hierarchies are manifested; Beatrice is the sole interpreter between the poet and the Angels, as she had been the revealer to him on earth of Love’s “possible divinities and celestial prophecies.”
