An excerpt from St. Gregory Nazianzus Second Oration on Easter:
I will stand upon my watch, saith the venerable Habakkuk; and I will take my post beside him today on the authority and observation which was given me of the Spirit; and I will look forth, and will observe what shall be said to me. Well, I have taken my stand, and looked forth; and behold a man riding on the clouds and he is very high, and his countenance is as the countenance of Angel, and his vesture as the brightness of piercing lightning; and he lifts his hand toward the East, and cries with a loud voice. His voice is like the voice of a trumpet; and round about Him is as it were a multitude of the Heavenly Host; and he saith, Today is salvation come unto the world, to that which is visible, and to that which is invisible. Christ is risen from the dead, rise ye with Him. Christ is returned again to Himself, return ye. Christ is freed from the tomb, be ye freed from the bond of sin. The gates of hell are opened, and death is destroyed, and the old Adam is put aside, and the New is fulfilled; if any man be in Christ he is a new creature; be ye renewed. Thus he speaks; and the rest sing out, as they did before when Christ was manifested to us by His birth on earth, their glory to God in the highest, on earth, peace, goodwill among men.
And with them I also utter the same words among you. And would that I might receive a voice that should rank with the Angel’s, and should sound through all the ends of the earth.
