II. He promises to accept Anatolius on making this confession, and asks for a council in Italy to finally define the Faith.
But because both we and our blessed fathers, whose teaching we revere and follow, are in concord on the one Faith, as the bishops of all the provinces attest, let your clemency's most devout faith see to it that such a document as is due may reach us as soon as may be from the bishop of Constantinople, as from an approved and Catholic priest, that is, openly and distinctly affirming that he will separate from his communion any one who believes or maintains any other view about the Incarnation of the Word of God than my statement and that of all Catholics lays down, that we may fairly be able to bestow on him brotherly love in Christ. And that swifter and fuller effect, God aiding us, may be given through your clemency's faith to our wholesome desires, I have sent to your piety my brethren and fellow bishops Abundius and Asterius, together with Basilius and Senator presbyters, whose devotion is well proved to me, through whom, when they have displayed the instructions which we have sent, you may be able properly to apprehend what is the standard of our faith, so that, if the bishop of Constantinople gives his hearty assent to the same confession, we may securely, as is due, rejoice over the peace of the Church and no ambiguity may seem to lurk behind which may trouble us with perhaps ungrounded suspicions. But if any dissent from the purity of our Faith and from the authority of the Fathers, the Synod which has met at Rome for that purpose joins with me in asking your clemency to permit a universal council within the limits of Italy; so that, if all those come together in one place who have fallen either through ignorance or through fear, measures may be taken to correct and cure them, and no one any longer may be allowed to quote the Synod of Nicæa in a way which shall prove him opposed to its Faith; since it will be of advantage both to the whole Church and to your rule, if one God, one Faith and one mystery of man's Salvation, be held by the one confession of the whole world.
