Whatever a man loves he inevitably clings to, and in order not to lose it he rejects everything that keeps him from it. So he who loves God cultivates pure prayer, driving out every passion that keeps him from it. He who drives out self-love, the mother of the passions, will with God's help easily rid himself of the rest, such as anger, irritation, rancor and so on. But he who is dominated by self-love is overpowered by the other passions, even against his will. Self-love is the passion of attachment to the body.
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 ConfessorTo harbor no envy, no anger, no resentment against an offender is still not to have charity for him. It is possible, without any charity, to avoid rendering evil for evil. But to render, spontaneously, good for evil - such belongs to a perfect spiritual love.
Maximus the ConfessorHe who is a beginner on the way must not be brought to practise the commandments by kindness alone, but must more often be induced to continue the struggle by being rigorously reminded of God's judgment. In this way he will not only be moved by love to desire what is divine, but will be moved by fear to avoid what is evil. For 'I will sing to Thee, O Lord, of mercy and judgment' (Ps. 101:1 LXX). He will sing to God charmed by love, and steeled by fear he will have strength for the song.
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 ConfessorCreated man cannot become a son of God and god by grace through deification, unless he is first through his own free choice begotten in the Spirit by means of the self-loving and independent power dwelling naturally in him.
Maximus the Confessor... for our sake loosing within Himself the bonds of bodily birth, He granted us through spiritual birth, according to our own volition, power to become children of God instead of children of flesh and blood if we have faith in His Name (cf. Jn. 1:12-13). For the Savior the sequence was, first of all, incarnation and bodily birth for my sake; and so thereupon the birth in the Spirit through baptism, originally spurned by Adam, for the sake of my salvation and restoration by grace, or, to describe it even more vividly, my very remaking.
