IX. Leontius is appointed in Hilary's room.
Wherefore, because our desire seems very different to this (for we are anxious that the settled state of all the Churches and the harmony of the priests should be maintained,) exhorting you to unity in the bond of love, we both entreat, and consistently with our affection admonish you, in the interests of your peace and dignity, to keep what has been decreed by us at the inspiration of God and the most blessed Apostle Peter, after sifting and testing all the matters at issue, being assured that what we are known to have decided in this way is not so much to our own advantage as to yours.
For we are not keeping in our own hands the ordinations of your provinces, as perhaps Hilary, with his usual untruthfulness, may suggest in order to mislead your minds, holy brethren: but in our anxiety we are claiming for you that no further innovations should be allowed, and that for the future no opportunity should be given for the usurper to infringe your privileges. For we acknowledge that it can only redound to our credit, if the diligence of the Apostolic See be kept unimpaired among you, and if in our maintenance of Apostolic discipline we do not allow what belongs to your position to fall to the ground through unscrupulous aggressions.
And since seniority is always to be respected, we wish Leontius, our brother and fellow bishop, a priest well approved among you, to be promoted to this dignity, if it please you that without his consent no further council be summoned by you, holy brethren, and that he may be honoured by you all as his age and good fame demands, the metropolitans being secured in their own dignity and rights. For it is but fair, and no injury seems to accrue to any of the brethren, if those who come first in seniority of the priesthood should, as their age deserves, have deference paid to them by the rest of the priests in their own provinces. God keep you safe, beloved brethren.
