Letter XXXVII332 This letter is on the same subject as Lett. XXIX. above, but as the wording of it contains some interesting matter, it is here given in full. There is no Gk. version extant, and how there came to be two letters within a week of one another on the same topic is not clear..

To Theodosius Augustus.

Leo to Theodosius Augustus.

Unity of Faith is essential but the point at issue hardly required a general council, it is so clear.

On receiving your clemency’s letter, I perceived that the universal Church has much cause for joy, that you will have the Christian Faith, whereby the Divine Trinity is honoured and worshipped, to be different or out of harmony with itself in nothing. For what more effectual support can be given to human affairs in calling upon God’s mercy than when one thanksgiving, and the sacrifice of one confession is offered to His majesty by all. Wherein the devotions of the priests and all the faithful will reach at last their completeness, if in what was done for our redemption by God the Word, the only Son of God, nothing else be believed than what He Himself ordered to be preached and believed. Wherefore although every consideration prevents my attendance on the day which your piety has fixed for the councils of bishops333 Cf. Lett. XXIX. above, and especially XXXI., chap. iv., where the reasons are given rather more fully.: for there are no precedents for such a thing, and the needs of the times do not allow me to leave the city, especially as the point of Faith at issue is so clear, that it would have been more reasonable to abstain from proclaiming a synod: yet as far as the Lord vouchsafes to help me, I have bestowed my zeal upon obeying your clemency’s commands, by appointing my brethren who are competent to act as the case requires in removing offences, and who can represent me: because no question has arisen on which there can or ought to be any doubt. Dated 21st of June, in the consulship of the illustrious Asturius and Protogenes, (449).
