Apostolic Constitutions, Book VIII 3

1We have now finished the first part of this discourse concerning gifts, whatever they be, which God has bestowed upon men according to His own will; and how He rebuked the ways of those who either attempted to speak lies, or were moved by the spirit of the adversary; and that God often employed the wicked for prophecy and the performance of wonders. But now our discourse hastens as to the principal part, that is, the constitution of ecclesiastical affairs, that so, when you have learned this constitution from us, you who are ordained bishops by us at the command of Christ, may perform all things according to the commands delivered you, knowing that he that hears us hears Christ, and he that hears Christ hears His God and Father, to whom be glory forever. Amen.
