A passion is a contranatural movement of the soul or an irrational love, or an blindfold hatred toward any material thing, or because of it: for example, for food, or for women, or for riches, or for worldly glory, or any other sensible thing; or for the sake of such things, as in a senseless hatred for someone on account of the things mentioned above.
Maximus the ConfessorIf you are remembering evil against someone, then pray for him; and as you remove through prayer the pain of the remembrance of the evil he has done, you will stop the advance of the passion. And when you have attained brotherly love and love for mankind, you will completely cast this passion out of your soul. Then when someone else does evil to you, be affectionate and humble toward him, and treat him kindly, and you will deliver him from this passion.
Maximus the ConfessorEvery genuine confession humbles the soul. When it takes the form of thanksgiving, it teaches the soul that it has been delivered by the grace of God.
Maximus the ConfessorGod, Who is by nature good and dispassionate, loves all men equally as His handiwork. But He glorifies the virtuous man because in his will he is united to God. At the same time, in His goodness he is merciful to the sinner and by chastising him in this life brings him back to the path of virtue. Similarly, a man of good and dispassionate judgment also loves all men equally. He loves the virtuous man because of his nature and the probity of his intention; and he loves the sinner, too, because of his nature and because in his compassion he pities him for foolishly stumbling in darkness.
Maximus the ConfessorIf you expound the teaching of the Logos from the standpoint of the moral life, using materialistic words and examples which correspond to the capacity of your hearers, you make the Logos flesh. Conversely, if you elucidate mystical theology by means of the higher forms of contemplation you make the Logos spirit.
