“Come then from the West, O imitator of Christ, arise and do not cast us off forever; to you Christ our God has said, “and when you have turned again, strengthen your brethren.” Behold the time and the place; help us, you who have been appointed by God for this, stretch out a hand as far as it is possible; you have the power from God FROM BEING FIRST AMONG ALL, in which position you were also placed. Terrify, we pray, the heretical beasts with the pipe of your divine word; O good shepherd, lay down your life for the sheep of Christ, we beseech you.”
And you’d be hard pressed to find someone more eastern than Theodore the Studite.
I noticed the link doesn’t work here. If you click on this post Salvation without Christ - #126 by 1Cor15.54 there is the same link I posted in the past and there it actually works. Strange.
