IV. He asks the Emperor to express his disapproval of Anatolius' self-seeking spirit.
And therefore knowing that your glorious clemency is anxious for the peace of the Church and extends its protection and approval to those measures which conduce to pacific unity, I pray and beseech you with earnest entreaty to refuse all sanction and protection to these unscrupulous attempts against Christian unity and peace, and put a salutary check upon my brother Anatolius' desires, which will only injure himself, if he persists: that he may not desire things which are opposed to your glory and the needs of the times, and wish to be greater than his predecessors, and that it may be free for him to be as pre-eminent as he can in virtues, in which he will be partaker only if he prefer to be adorned with love rather than puffed up with ambition.
The conception of this unwarrantable wish he ought indeed never to have received within the secret of his heart, but when my brothers and fellow bishops who were there to represent me withstood him, he might at least have desisted from his unlawful self-seeking at their wholesome opposition. For both your gracious Majesty and his own letter affirm that the legates of the Apostolic See opposed him as they ought with the most justifiable resistance, so that his presumption was the less excusable in that not even when rebuked did it restrain itself.
