Apostolic Constitutions, Book VIII 16

1Concerning the ordination of presbyters, I who am loved by the Lord make this constitution for you the bishops: When you ordain a presbyter, O bishop, lay your hand upon his head, in the presence of the presbyters and deacons, and pray, saying: O Lord Almighty, our God, who hast created all things by Christ, and in like manner takes care of the whole world by Him; for He who had power to make different creatures, has also power to take care of them, according to their different natures; on which account, O God, You take care of immortal beings by bare preservation, but of those that are mortal by succession — of the soul by the provision of laws, of the body by the supply of its wants. Do Thou therefore now also look down upon Your holy Church, and increase the same, and multiply those that preside in it, and grant them power, that they may labour both in word and work for the edification of Your people. Now look down also upon this Your servant, who is put into the presbytery by the vote and determination of the whole clergy; and replenish him with the Spirit of grace and counsel, to assist and govern Your people with a pure heart, in the same manner as You looked down upon Your chosen people, and commanded Moses to choose elders, whom You filled with Your Spirit. Do Thou also now, O Lord, grant this, and preserve in us the Spirit of Your grace, that this person, being filled with the gifts of healing and the word of teaching, may in meekness instruct Your people, and sincerely serve You with a pure mind and a willing soul, and may fully discharge the holy ministrations for Your people, through Your Christ, with whom glory, honour, and worship be to You, and to the Holy Ghost, forever. Amen.
