IV. He asks for a Latin translation of the acts of Chalcedon.
I wish to know whether my letter has been delivered to you, brother, which I sent you by Basil the deacon, upon the Faith of the Lord's Incarnation, while Flavian of holy memory was still alive; for I fancy you have never made any comment on its contents. We have no very clear information about the acts of the Synod, which were drawn up at the time of the council at Chalcedon, on account of the difference of language. And therefore I specially enjoin upon you, brother, that you have the whole collected into one volume, accurately translated of course into Latin, that we may not be in doubt on any portion of the proceedings, and that there may be no manner of uncertainty after you have taken pains to bring it fully within my understanding. Dated March 11th, in the consulship of the illustrious Opilio (453).
