As long as I remain imperfect and refractory, neither obeying God by practising the commandments nor becoming perfect in spiritual knowledge, Christ from my point of view also appears imperfect and refractory because of me. For I diminish and cripple Him by not growing in spirit with Him, since I am 'the body of Christ and one of its members' (I Cor. 12:27).
Maximus the ConfessorYou will be able to check envy if you rejoice with the man whom you envy whenever he rejoices, and grieve whenever he grieves.
Maximus the ConfessorA man who has been assiduous in acquiring the fruits of love will not cease loving even if he suffers a thousand calamities. Let Stephen, the disciple of Christ, and others like him persuade you of the truth of this (cf. Acts 7:60). Our Lord Himself prayed for His murderers and asked the Father to forgive them because they did not know what they were doing (cf. Luke 23:34).
Maximus the ConfessorA 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 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.
