Apostolic Constitutions 8.22
(4th Century CE)
XXII. Concerning readers, I Matthew, also called Levi, who was once a tax-gatherer, make a constitution: Ordain a reader by laying your hands upon him, and pray unto God, and say: O Eternal God, who art plenteous in mercy and compassions, who hast made manifest the constitution of the world by Your operations therein, and keepest the number of Your elect, do Thou also now look down upon Your servant, who is to be entrusted to read Your Holy Scriptures to Your people, and give him Your Holy Spirit, the prophetic Spirit. You who instructed Esdras Your servant to read Your laws to the people, do Thou now also at our prayers instruct Your servant, and grant that he may without blame perfect the work committed to him, and thereby be declared worthy of an higher degree, through Christ, with whom glory and worship be to You and to the Holy Ghost for ever. Amen.
