The Light of Christ illumines all.

... 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.

Being delivered from bodily sins is not enough; we must also cleanse the inner energy which dwells in our soul. For out of our hearts 'proceed evil thoughts, adulteries, fornications, murders, thefts, covetousness' (Mk. 7:21) and so on ? these are what motivate people.

...although divided in His various powers and energies, in each of His works the Holy Spirit is wholly present and active, undividedly divided, partaken of while remaining complete, like the sun's ray.

The Light of Christ illumines all.

Through the fall our nature was stripped of divine illumination and resplendence. But the Logos of God had pity upon our disfigurement, and in His compassion He took our nature upon Himself. On Tabor He manifested it to His elect disciples clothed once again most brilliantly. He showed what we once were and what we shall become through Him in the age to come if we choose to live our present life, as far as possible, in accordance with His ways.

...angels... are always being filled full of light, becoming ever more radiant and making blessed use of their natural ability to change. They dance for joy around the First Light, look continuously towards Him and are enlightened directly by Him, as they tirelessly sing the praises of the Fount of light and, being ministers of light, transmit illuminating grace to those lower beings who are being enlightened.
