As you were taken up from the mount of Olives, the powers seeing you cried one to the other: Who is this? And they were told: This is the Mighty One, the Powerful, this is the Powerful in war, this is truly the King of glory. And why are your garments scarlet? He has come from Bosor, that is, from the flesh. But as God seated at the right hand of the Majesty you have sent us the Holy Spirit, to guide and save our souls.
