Bless the LORD, O my soul! O LORD my God, You are very great! You are clothed with honor and majesty, who covers yourself with light as with a garment… (Psalm 104:1-2)
A very common idea among early Christians and also found in ancient Jewish writings is that Adam and Eve in Paradise were clothed with garments of light, given to them by God.
These garments were removed from them when they sinned, and thus they became aware of their nakedness and tried to cover themselves with leaves and hide themselves in the trees so that they would not have to stand naked before God. The reversal of this in the early Church occurred when each person undressed before their baptism. In baptism, they had nothing to hide, having confessed their sins (unlike Adam and Eve who tried to hide themselves and the fact that they had sinned), and so could stand naked before God and feel no shame. Following baptism, a special white garment was placed on the newly baptized signifying their putting on the garments of light again. And we sing the words of Galatians 3:27 – “For as many of you as were baptized into Christ have put on Christ.”
As one early Syriac Christian notes:
At the incarnation the Son ‘put on body’, and at His baptism in the Jordan He deposits the garment of glory in the river, so that it becomes once again available for human beings to put on. (Treasure House of Mysteries, p. 16)
Thus the baptism of Christ which we Orthodox commemorate in the Feast of Theophany is organically connected to our own baptisms. Christ, the incarnate God, is clothed in the garment of glory since He has not sinned. In His baptism, it is Christ who sanctifies the water rather than being sanctified by the water. In the Syriac Christian tradition, Christ deposits the garment of glory into the Jordan River. Before we baptize the catechumens, we pray over the water that God will send down upon the water “the blessing of Jordan”. That blessing is the garment of glory which the baptized receive as they emerge from the triune baptism.
St. Romanos the Melodist writes poetically:
In Galilee of the nations, in the country of Zavulon and the land of Naphthalim,
as the prophet said, a great light has shone – Christ.
For the darkened, a shining beam has appeared, blazing out of Bethlehem,
or, rather, out of Mary – the Lord, the sun of justice,
has made his rays dawn on the whole inhabited world.
Therefore let us all, Adam’s naked children,
put him on that we may be kept warm;
for as a covering for the naked and a light for the darkened
you have come, you have appeared,
the unapproachable Light.
(On the Life of Christ, p. 80)
