Thou didst ascend in glory, O Christ our God,But there is still more to it than that.
granting joy to Thy Disciples by the promise of the Holy Spirit.
Through the blessing, they were assured
that Thou art the Son of God,
the Redeemer of the world.
One of the hymns for Vespers says:
The nature of Adam,
which had descended to the nethermost parts of the earth,
Thou didst renew in Thyself, O God,
and today Thou didst take it up above every Principality and Pow’r,
for loving it, Thou didst seat it with Thyself;
and having compassion on it, Thou didst unite it with Thyself;
and united with it, Thou didst suffer with it;
and Thou Who art passionless hast glorified it with Thyself.
But the Bodiless Powers were asking:
“Who is this Man of beauty?
Not man only, but both God and man,
the two natures together made manifest.”
And so exultant Angels, flying about the Disciples in shining robes,
cried out: “Ye Men of Galilee,
He Who is gone from you,
this Jesus, both Man and God,
will come again as God and Man, the Judge of living and the dead,//
granting the faithful forgiveness of sins and His great mercy!”».
