On His departure from this world to the place whence He came, He repeated the beginning of His old descent, in order that the Word beheld at first in the bush, and afterwards taken up crowned by the thorn, might show the whole to be the work of one power, He Himself being one, the Son of the Father, who is truly one, the beginning and the end of time.
Clement of Alexandria
The Paedagogus, Book II
Chapter VIII
