He who busies himself with the sins of others, or judges his brother on suspicion, has not yet even begun to repent or to examine himself so as to discover his own sins.

We must not only put bodily passions to death but also destroy the soul's impassioned thoughts. Hence the Psalmist says, 'Early in the morning I destroyed all the wicked of the earth, that I might cut off all evil-doers from the city of the Lord' (Ps. 101:8) - that is, the passions of the body and the soul's godless thoughts.

If you expound the teaching of the Logos from the standpoint of the moral life, using materialistic words and examples which correspond to the capacity of your hearers, you make the Logos flesh. Conversely, if you elucidate mystical theology by means of the higher forms of contemplation you make the Logos spirit.

Our forefather Adam... used his freedom to turn toward what was worse and to direct his desire away from what had been permitted to what was forbidden. It was in his power 'to be united to the Lord and become one spirit with God...' (I Cor. 6:15). But Adam was deceived and chose to cut himself off voluntarily from God's happy end for him, preferring by his own free choice to be drawn down to the earth (cf. Gen. 2:17) than to become God by grace.

Cleanse your mind from anger, remembrance of evil, and shameful thoughts, and then you will find out how Christ dwells in you.

Some passions are bodily, other spiritual. Bodily passions have their sources in the body, while spiritual ones come from external things. But love and temperance cut out both the one and the other: Love cuts out spiritual passions, and temperance bodily ones.
