Reply Obj. 3: Natural love is said to be of the end, not as of that end to which good is willed, but rather as of that good which one wills for oneself, and in consequence for another, as united to oneself. Nor can such natural love be stripped from the wicked angels, without their still retaining a natural affection towards the good angels, in so far as they share the same nature with them. But they hate them, in so far as they are unlike them according to righteousness and unrighteousness. _______________________
FIFTH ARTICLE [I, Q. 60, Art. 5]
Whether an angel by natural love loves God more than he loves himself?
Objection 1: It would seem that the angel does not love God by natural love more than he loves himself. For, as was stated (A. 4), natural love rests upon natural union. Now the Divine nature is far above the angelic nature. Therefore, according to natural love, the angel loves God less than self, or even than another angel.
Obj. 2: Further, "That on account of which a thing is such, is yet more so." But every one loves another with natural love for his own sake: because one thing loves another as good for itself. Therefore the angel does not love God more than self with natural love.
Obj. 3: Further, nature is self-centered in its operation; for we behold every agent acting naturally for its own preservation. But nature's operation would not be self-centered were it to tend towards anything else more than to nature itself. Therefore the angel does not love God more than himself from natural love.
Obj. 4: Further, it is proper to charity to love God more than self. But to love from charity is not natural to the angels; for "it is poured out upon their hearts by the Holy Spirit Who is given to them," as Augustine says (De Civ. Dei xii, 9). Therefore the angels do not love God more than themselves by natural love.
Obj. 5: Further, natural love lasts while nature endures. But the love of God more than self does not remain in the angel or man who sins; for Augustine says (De Civ. Dei xiv), "Two loves have made two cities; namely love of self unto the contempt of God has made the earthly city; while love of God unto the contempt of self has made the heavenly city." Therefore it is not natural to love God more than self.
On the contrary, All the moral precepts of the law come of the law of nature. But the precept of loving God more than self is a moral precept of the law. Therefore, it is of the law of nature. Consequently from natural love the angel loves God more than himself.
I answer that, There have been some who maintained that an angel loves God more than himself with natural love, both as to the love of concupiscence, through his seeking the Divine good for himself rather than his own good; and, in a fashion, as to the love of friendship, in so far as he naturally desires a greater good to God than to himself; because he naturally wishes God to be God, while as for himself, he wills to have his own nature. But absolutely speaking, out of the natural love he loves himself more than he does God, because he naturally loves himself before God, and with greater intensity.
