... we grapple with this 'law of sin' (Rom. 8:2) and expel it from our body, establishing in its place the surveillance of the intellect. Through this surveillance we prescribe what is fitting for every faculty of the soul and every member of the body. For the senses we prescribe what they should take into account and to what extent they should do so, and this exercise of the spiritual law is called self-control.
Gregory PalamasAnyone who has fallen into fornication, adultery or any other such bodily impurity, should desist from this revolting filth and cleanse himself through confession, tears, fasting and the like. For God judges unrepentant fornicators and adulterers. He condemns them, dismisses them and consigns them to hell, unquenchable fire and other never-ending punishments, saying, 'Let the impure and accursed be taken away, lest they see and enjoy the glory of the Lord' (cf. Isa. 26:10 LXX).
Gregory PalamasBeing bodiless, God is nowhere, but as God He is everywhere. If there were a mountain, a place or any part of Creation where God was not, then He would be found to be in some way circumscribed. So He is everywhere and in everything. In what way is this so? Is He contained not by each part but by the whole? No, because then that would be a body. He embraces and encompasses everything, and is Himself everywhere and also above everything, worshipped by true worshippers in His Spirit and Truth.
Gregory PalamasWe know that prayer in and of itself cannot save us, but carrying it out before God can. For when the Lord's eyes are upon us He sanctifies us, as the sun warms everything upon which it shines.
Gregory PalamasThe Lord came to send fire upon the earth (cf. Lk. 12:49), and through participation in this fire He makes divine not just the human substance which He assumed for our sake, but every person who is found worthy of communion with Him.
Gregory PalamasYou should secretly give from what you have to those in need, so that you receive from God, Who sees in secret, a hundred times more, as well as life eternal in the age to come (cf. Mt. 6:4; Mk. 10:30).
Gregory PalamasEven when your body does nothing, sin can be active in your mind. When your soul inwardly repulses the evil one's attack by means of prayer, attention, remembrance of death, godly sorrow and mourning the body, too, takes its share of holiness, having acquired freedom from evil actions. This is what the Lord meant by saying that someone who cleans the outside of the cup has not cleansed it inside, but clean the inside and the whole cup will be clean
