Why then is this day called Theophany? Because Christ made Himself known to all -- not then when He was born -- but then when He was baptised. Until this time He was not known to the people. And that the people did not know Him, Who He was...
The experience of the ages shows that the sign of the cross has great power over all a person’s actions during the entire course of his life. Therefore it is necessary to strive to root in children the habit of protecting themselves with the sign of the cross often, especially when receiving food and drink, going to bed and waking up, before departing somewhere in a vehicle, before leaving and entering any place; and they should not make the sign carelessly or according to fashion, but precisely, beginning with the forehead to the solar plexus, then to both shoulders, so that a proper cross is produced.... The sign of the cross has saved many from great dangers and afflictions.
Pray before your body takes rest on your bed... If you are tempted, make the Sign (of the Cross) on your forehead reverently… for this is a known and tested weapon against the Devil.
And Jesus, when He was baptised, went up straightway out of the water; and lo, the heavens were opened unto Him, and He saw the Spirit of God descending like a dove, and lighting upon Him; and lo, a voice from heaven saying: 'This is My beloved Son, in whom I am well pleased.' The Spirit did not descend on Christ while He was down in the water, but when He came out of it. By this, the wisdom of God seeks to show us that the Spirit of God does not descend on the old man, who is alive to sin and dead to God, but only on the man spiritually re-born, who has died to sin and come alive to God.
