Apostolic Tradition 22

1Then the bishop, laying his hand upon them, shall pray, saying: O Lord God, who hast made them worthy to obtain remission of sins through the laver of regeneration of [the] Holy Spirit, send into them thy grace, that they may serve thee according to thy will; for thine is the glory, to the Father and the Son, with [the] Holy Spirit in the holy church, both now and world without end. Amen. Then, pouring the oil of thanksgiving from his hand and putting it on his forehead, he shall say: I anoint thee with holy oil in the Lord, the Father Almighty and Christ Jesus and [the] Holy Ghost. And signing them on the forehead he shall say: The Lord be with thee; and he who is signed shall say: And with thy spirit. And so he shall do to each one. And immediately thereafter they shall join in prayer with all the people, but they shall not pray with the faithful until all these things are completed. And at the close of their prayer they shall give the kiss of peace.
