The man who has struggled bravely with the passions of the body, has fought ably against unclean spirits, and has expelled from his soul the conceptual images they provoke, should pray for a pure heart to be given him and for a spirit of integrity to be renewed within him (cf. Ps. 51:10). In other words, he should pray that by grace he may be completely emptied of evil thoughts and filled with divine thoughts, so that he may become a spiritual world of God, splendid and vast, wrought from moral, natural and theological forms of contemplation.
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 Confessor...one's movement towards the divine reaches its end only when one reaches God... 'The true Sabbaths are the rest laid up for the people of God' (Heb. 4:9). God can 'bear these sabbaths' (cf. Is. 1:13) because they are true. And the one 'in which the world is crucified' (Gal. 6:14) reaches these sabbaths of rest because he has clearly turned away from worldly things and returned to his own spiritual resting place. The one who arrives there will no longer be moved from his place, for there he finds quiet and tranquility.
Maximus the ConfessorAs we have borne the image of the earthy, let us also bear the image of the heavenly
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.
