He who through virtue and spiritual knowledge has brought his body into harmony with his soul has become a harp, a flute and a temple of God. He has become a harp by preserving the harmony of the virtues; a flute by receiving the inspiration of the Spirit through divine contemplation; and a temple by becoming a dwelling place of the Logos through the purity of his intellect.
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 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 ConfessorNo benefit comes from a just man's prayer if he who asks for it finds more pleasure in sin than in virtue. For Samuel mourned over Saul when he sinned, but he was not able to obtain God's mercy, for his grief was not supported by the necessary change of life on the part of the sinner. Hence God put an end to the pointless grief of His servant, saying to him, 'How long will you mourn for Saul, seeing I have rejected him from reigning over Israel?' (I Sam. 16:1).
Maximus the ConfessorHe who has realized love for God in his heart is tireless in his pursuit of the Lord his God, and bears every hardship, reproach and insult nobly, never thinking the least evil of anyone.
Maximus the ConfessorThose who, animal-like, live solely according to the senses... misuse God's creation in order to indulge the passions. They do not understand the principle of that wisdom which is revealed to all: that we should know and praise God through His creation and that by means of the visible world we should understand whence we came, what we are, for what purpose we were made and where we are going. On the contrary, they travel through this present age in darkness... with... ignorance of God.
