Open the gate of Eden

HEAR, O heaven, and give ear, O earth: for behold, the Son and Word of God and the Father cometh forth to be born of a maid that hath not known any man, in the good pleasure of him that hath begotten him impassibly, and by the co-operation of the holy Spirit.

Bethlehem, prepare thyself; Eden, open thy Gate; for He Who Is becometh that which was not, and he that fashioned all creation is fashioned throughly, even he that granteth his great mercy to the world.

At Vespers on the Sunday before Christmas Day.
