discord

153. Discord is a discrepancy of the will which prevents it from conforming to the will of God in such matters as it ought to conform for the glory of God and the good of the neighbour; and it is a grave sin, because St. Paul counts dissensions among those sins which exclude those who commit them from the kingdom of Heaven. [Gal. v, 20] And God declares His hatred and abhorrence of all those that disseminate discord among their neighbours. [Prov. vi, 9] Dissensions arise generally from pride, which prompts us to over-esteem ourselves and to set our own welfare and opinions against those of others, and from this arises the quarreling, litigation, obstinacy, slandering, faction, hatred, strife and many other evils without number and without end. [St. Thomas 22, qu. xxxvii, art. 1 et 2; et qu. xxxviii, art. 2; et qu. cxxxii, art. 5]

Recollect yourself now interiorly, and examine yourself, and having found that under one or other of these headings pride really dominates you, judge how necessary it is for you to fight against it with humility, because if pride is conquered, a host of other sins will be conquered also. And in order to give yourself courage remember this, that before the tribunal of God the proud will be condemned, and only the humble can hope to find mercy. To say that we are humble is the same as to say that we are amongst the elect and shall be saved; and to say that we are proud is the same as to say we are reprobate and lost. "Pride is a sure sign of the reprobate, as humility is the sign of the elect." [Hom. 7 in Evang.; et lib. 3, Mor. cap xviii] We owe this conclusion to St. Gregory
