Theology without practice is the theology of demons

Just as the light of the sun attracts a healthy eye, so through love knowledge of God naturally draws to itself a pure intellect.

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.

It 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.

The Logos came down out of love for us. Let us not keep Him down permanently, but let us go up with Him to the Father, leaving the earth and earthly things behind, lest He say to us what He said to the Jews because of their stubbornness: 'I go where you cannot come (Jn. 8:21).

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.

If the words of God are uttered merely as verbal expressions, and their message is not rooted in the virtuous way of life of those who utter them, they will not be heard. But if they are uttered through the practice of the commandments, their sound has such power that they dissolve the demons and dispose men eagerly to build their hearts into temples of God through making progress in works of righteousness.
