The 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. A soul filled with thoughts of sensual desire and hatred is unpurified. If we detect any trace of hatred in our hearts against any man whatsoever for committing any fault, we are utterly estranged from love for God, since love for God absolutely precludes us from hating any man.
Maximus the ConfessorMore Maximus the Confessor quotes
Do not say that faith in Christ alone can save you, for this is not possible if you do not attain love for Him, which is demonstrated by deeds. As for mere faith: "The demons also believe and tremble" (James, 2:19). The action of love consists in heartfelt good deeds toward one's neighbor, magnanimity, patience, and sober use of things.
Maximus the Confessor
If God suffers in the flesh when He is made man, should we not rejoice when we suffer, for we have God to share our sufferings? This shared suffering confers the kingdom on us. For he spoke truly who said, 'If we suffer with Him, then we shall also be glorified with Him' (Rom. 8:17).
Maximus the Confessor
But 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.
