In the first way, love of one's friend surpasses love of one's enemy, because a friend is both better and more closely united to us, so that he is a more suitable matter of love and consequently the act of love that passes over this matter, is better, and therefore its opposite is worse, for it is worse to hate a friend than an enemy.
In the second way, however, it is better to love one's enemy than one's friend, and this for two reasons. First, because it is possible to love one's friend for another reason than God, whereas God is the only reason for loving one's enemy. Secondly, because if we suppose that both are loved for God, our love for God is proved to be all the stronger through carrying a man's affections to things which are furthest from him, namely, to the love of his enemies, even as the power of a furnace is proved to be the stronger, according as it throws its heat to more distant objects. Hence our love for God is proved to be so much the stronger, as the more difficult are the things we accomplish for its sake, just as the power of fire is so much the stronger, as it is able to set fire to a less inflammable matter.
Yet just as the same fire acts with greater force on what is near than on what is distant, so too, charity loves with greater fervor those who are united to us than those who are far removed; and in this respect the love of friends, considered in itself, is more ardent and better than the love of one's enemy.
Reply Obj. 1: The words of Our Lord must be taken in their strict sense: because the love of one's friends is not meritorious in God's sight when we love them merely because they are our friends: and this would seem to be the case when we love our friends in such a way that we love not our enemies. On the other hand the love of our friends is meritorious, if we love them for God's sake, and not merely because they are our friends.
The Reply to the other Objections is evident from what has been said in the article, because the two arguments that follow consider the reason for loving, while the last considers the question on the part of those who are loved. _______________________
EIGHTH ARTICLE [II-II, Q. 27, Art. 8]
Whether It Is More Meritorious to Love One's Neighbor Than to Love
God?
Objection 1: It would seem that it is more meritorious to love one's neighbor than to love God. For the more meritorious thing would seem to be what the Apostle preferred. Now the Apostle preferred the love of our neighbor to the love of God, according to Rom. 9:3: "I wished myself to be an anathema from Christ for my brethren." Therefore it is more meritorious to love one's neighbor than to love God.
Obj. 2: Further, in a certain sense it seems to be less meritorious to love one's friend, as stated above (A. 7). Now God is our chief friend, since "He hath first loved us" (1 John 4:10). Therefore it seems less meritorious to love God.
Obj. 3: Further, whatever is more difficult seems to be more virtuous and meritorious since "virtue is about that which is difficult and good" (Ethic. ii, 3). Now it is easier to love God than to love one's neighbor, both because all things love God naturally, and because there is nothing unlovable in God, and this cannot be said of one's neighbor. Therefore it is more meritorious to love one's neighbor than to love God.
