A Christian receives divine wisdom in three ways: by the commandments, teachings, and faith. The commandments free the mind from passions. Teachings lead it to true knowledge of nature. Faith leads to the contemplation of the Holy Trinity.
Maximus the ConfessorHe 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 ConfessorHe has as yet no perfect love, whose disposition towards men depends on what they are like, loving one and despising another for this or that, or sometimes loving, sometimes hating one and the same man. Blessed is the man who can love all men equally.
Maximus the ConfessorBlessed is he who like Joshua (cf. Josh. 10:12-13) keeps the Sun of righteousness from setting in himself throughout the whole day of his present life, not allowing it to be blotted out by the dusk of sin and ignorance. In this way he will truly be able to put to flight the cunning demons that rise up against him.
Maximus the ConfessorThe person who loves God cannot help loving every man as himself, even though he is grieved by the passions of those who are not yet purified. But when they amend their lives, his delight is indescribable and knows no bounds.
Maximus the ConfessorBut I say to you, the Lord says, love your enemies, do good to those who hate you, pray for those who persecute you. Why did he command these things? So that he might free you from hatred, sadness, anger and grudges, and might grant you the greatest possession of all, perfect love, which is impossible to possess except by the one who loves all equally in imitation of God.
