Reply Obj. 2: Parts are assigned to a principal virtue by reason of a sameness, not of subject or matter, but of formal mode, as stated above (Q. 137, A. 2, ad 1; Q. 157, A. 3, ad 2). Consequently, although humility is in the irascible as its subject, it is assigned as a part of modesty or temperance by reason of its mode.
Reply Obj. 3: Although humility and magnanimity agree as to matter, they differ as to mode, by reason of which magnanimity is reckoned a part of fortitude, and humility a part of temperance. _______________________
FIFTH ARTICLE [II-II, Q. 161, Art. 5]
Whether Humility Is the Greatest of the Virtues?
Objection 1: It would seem that humility is the greatest of the virtues. For Chrysostom, expounding the story of the Pharisee and the publican (Luke 18), says [*Eclog. hom. vii de Humil. Animi.] that "if humility is such a fleet runner even when hampered by sin that it overtakes the justice that is the companion of pride, whither will it not reach if you couple it with justice? It will stand among the angels by the judgment seat of God." Hence it is clear that humility is set above justice. Now justice is either the most exalted of all the virtues, or includes all virtues, according to the Philosopher (Ethic. v, 1). Therefore humility is the greatest of the virtues.
Obj. 2: Further, Augustine says (De Verb. Dom., Serm. [*S. 10, C. 1]): "Are you thinking of raising the great fabric of spirituality? Attend first of all to the foundation of humility." Now this would seem to imply that humility is the foundation of all virtue. Therefore apparently it is greater than the other virtues.
Obj. 3: Further, the greater virtue deserves the greater reward. Now the greatest reward is due to humility, since "he that humbleth himself shall be exalted" (Luke 14:11). Therefore humility is the greatest of virtues.
Obj. 4: Further, according to Augustine (De Vera Relig. 16), "Christ's whole life on earth was a lesson in moral conduct through the human nature which He assumed." Now He especially proposed His humility for our example, saying (Matt. 11:29): "Learn of Me, because I am meek and humble of heart." Moreover, Gregory says (Pastor. iii, 1) that the "lesson proposed to us in the mystery of our redemption is the humility of God." Therefore humility would seem to be the greatest of virtues.
On the contrary, Charity is set above all the virtues, according to Col. 3:14, "Above all . . . things have charity." Therefore humility is not the greatest of virtues.
I answer that, The good of human virtue pertains to the order of reason: which order is considered chiefly in reference to the end: wherefore the theological virtues are the greatest because they have the last end for their object. Secondarily, however, it is considered in reference to the ordering of the means to the end. This ordinance, as to its essence, is in the reason itself from which it issues, but by participation it is in the appetite ordered by the reason; and this ordinance is the effect of justice, especially of legal justice. Now humility makes a man a good subject to ordinance of all kinds and in all matters; while every other virtue has this effect in some special matter. Therefore after the theological virtues, after the intellectual virtues which regard the reason itself, and after justice, especially legal justice, humility stands before all others.
