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... Adam had trusted in God and been nourished from the tree of life (Gn. 2:9)? he would not have set aside the immortality that had been granted. For such immortality is eternally preserved by participation in life, since all life is genuine and preserved by appropriate food. The food of that blessed life is 'the bread that came down from heaven and gives life to the world' (Jn. 6:33), just as the inerrant Word Himself declares about Himself in the Gospels.
Maximus the ConfessorIt is one thing to be delivered from bad thoughts, and another to be freed from the passions. Often people are delivered from thoughts, when they do not have before their eyes those things which produce passion. But the passions for them remain hidden in the soul, and when the things appear again the passions are revealed. Therefore it is necessary to guard the mind when these things appear, and to know toward which things you have a passion.
Maximus the ConfessorWhen what has been created in time according to the temporal order has reached maturity, it ceases from natural growth. But when what has been brought about by the knowledge of God through the practice of the virtues has reached maturity, it starts to grow anew. For the end of one stage constitutes the starting point of the next.
Maximus the ConfessorIf you make provision for the desires of the flesh and bear a grudge against your neighbor on account of something transitory, you worship the creature instead of the Creator.
Maximus the ConfessorDo not say that faith in Christ alone can save you, for this is not possible if you do not attain love for Him, which is demonstrated by deeds. As for mere faith: "The demons also believe and tremble" (James, 2:19). The action of love consists in heartfelt good deeds toward one's neighbor, magnanimity, patience, and sober use of things.
