Whether charity is a virtue?

Objections

Objection 1 : It would seem that charity is not a virtue. For charity is a kind of friendship. Now philosophers do not reckon friendship a virtue, as may be gathered from Ethic. viii, 1; nor is it numbered among the virtues whether moral or intellectual. Neither, therefore, is charity a virtue.
Objection 2 : Further, "virtue is the ultimate limit of power" (De Coelo et Mundo i, 11). But charity is not something ultimate, this applies rather to joy and peace. Therefore it seems that charity is not a virtue, and that this should be said rather of joy and peace.
Objection 3 : Further, every virtue is an accidental habit. But charity is not an accidental habit, since it is a more excellent thing than the soul itself: whereas no accident is more excellent than its subject. Therefore charity is not a virtue.
