Apostolic Constitutions, Book VIII 21
1Concerning the sub-deacons, I Thomas make this constitution for you the bishops: When you ordain a subdeacon, O bishop, you shall lay your hands upon him, and say: O Lord God, the Creator of heaven and earth, and of all things that are therein; who also in the tabernacle of the testimony appointed overseers and keepers of Your holy vessels; do Thou now look down upon this Your servant, appointed a subdeacon; and grant him the Holy Spirit, that he may worthily handle the vessels of Your ministry, and do Your will always, through Your Christ, with whom glory, honour, and worship be to You and to the Holy Spirit forever. Amen.
