There is, however, a kind of envy which is accounted among the most grievous sins, viz. envy of another's spiritual good, which envy is a sorrow for the increase of God's grace, and not merely for our neighbor's good. Hence it is accounted a sin against the Holy Ghost, because thereby a man envies, as it were, the Holy Ghost Himself, Who is glorified in His works.
Reply Obj. 3: The number of envy's daughters may be understood for the reason that in the struggle aroused by envy there is something by way of beginning, something by way of middle, and something by way of term. The beginning is that a man strives to lower another's reputation, and this either secretly, and then we have tale-bearing, or openly, and then we have detraction. The middle consists in the fact that when a man aims at defaming another, he is either able to do so, and then we have joy at another's misfortune, or he is unable, and then we have grief at another's prosperity. The term is hatred itself, because just as good which delights causes love, so does sorrow cause hatred, as stated above (Q. 34, A. 6). Grief at another's prosperity is in one way the very same as envy, when, to Wit, a man grieves over another's prosperity, in so far as it gives the latter a good name, but in another way it is a daughter of envy, in so far as the envious man sees his neighbor prosper notwithstanding his efforts to prevent it. On the other hand, joy at another's misfortune is not directly the same as envy, but is a result thereof, because grief over our neighbor's good which is envy, gives rise to joy in his evil. _______________________
QUESTION 37
OF DISCORD, WHICH IS CONTRARY TO PEACE
(In Two Articles)
We must now consider the sins contrary to peace, and first we shall consider discord which is in the heart, secondly contention, which is on the lips, thirdly, those things which consist in deeds, viz. schism, quarrelling, war, and sedition. Under the first head there are two points of inquiry:
(1) Whether discord is a sin?
(2) Whether it is a daughter of vainglory? _______________________
FIRST ARTICLE [II-II, Q. 37, Art. 1]
Whether Discord Is a Sin?
Objection 1: It would seem that discord is not a sin. For to disaccord with man is to sever oneself from another's will. But this does not seem to be a sin, because God's will alone, and not our neighbor's, is the rule of our own will. Therefore discord is not a sin.
