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 ConfessorA soul that is nurtured by hatred toward man can not be at peace with God, Who has said: If you forgive not men their sins, neither shall your Father forgive your sins (Matt. 6:15). If a man does not want to be reconciled, you must at least guard yourself from hating, praying with a pure heart for him, and speaking no evil of him.
Maximus the ConfessorWithout the power of intelligence there is no capacity for spiritual knowledge; and without spiritual knowledge we cannot have the faith from which springs that hope whereby we grasp things of the future as though they were present. Without the power of desire there is no longing, and so no love, which is the issue of longing; for the property of desire is to love something. And without the incensive power, intensifying the desire for union with what is loved, there can be no peace, for peace is truly the complete and undisturbed possession of what is desired.
Maximus the ConfessorThe patient endurance of the saints exhausts the evil power that attacks them, since it makes them glory in sufferings undergone for the sake of the truth. It teaches those too much concerned with a life in the flesh to deepen themselves through such sufferings instead of pursuing ease and comfort; and it makes the flesh's natural weakness in the endurance of suffering a foundation for overwhelming spiritual power. For the natural weakness of the saints is precisely such a foundation, since the Lord has made their weakness stronger than the proud devil.
Maximus the ConfessorJust as the thought of fire does not warm the body, so faith without love does not actualize the light of spiritual knowledge in the soul.
Maximus the ConfessorFor him who is perfect in love and has reached the summit of dispassion there is no difference between his own or another's, or between Christians and unbelievers, or between slave and free, or between male and female. But because he has risen above the tyranny of the passions and has fixed his attention on the single nature of man, he looks on all in the same way and shows the same disposition to all. For in him there is neither Greek nor Jew, male nor female, bond not free, but Christ who 'is all, and in all' (Col. 3:11; cf. Gal. 3:28).
