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 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 ConfessorThere are lots of those who speak but few who do. However, no one should distort the word of God by his own negligence, but it is better to confess your own weakness, not hiding the truth of God, so that together with the breaking of the commandments you do not also appear guilty of an untrustworthy explanation of the word of God.
Maximus the ConfessorAs 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 ConfessorIn conformity with the philosophy of Christ, let us make of our life a training for death.
