Faith, dearly-beloved, which alone makes us true Christians, and which, as we hear with approval, you are defending with loyal zeal and praiseworthy affection, hold fast and maintain boldly. And since, besides God’s aid, you must win the favour of catholic Princes also, humbly and wisely make request that the most clement Emperor be pleased to grant our petition, wherein we have asked for a plenary synod to be convened; that by the aid of God’s mercy the sound may be increased in courage, and the sick, if they consent to be treated, have the remedy applied. (Dated October 15, in the consulship of the illustrious Asturius and Protogenes, 449.)
