This baptism, therefore, is given into the death of Jesus: the water is instead of the burial, and the oil instead of the Holy Ghost; the seal instead of the cross; the ointment is the confirmation of the confession; the mention of the Father as of the Author and Sender; the joint mention of the Holy Ghost as of the witness; the descent into the water the dying together with Christ; the ascent out of the water the rising again with Him. The Father is the God over all; Christ is the only-begotten God, the beloved Son, the Lord of glory; the Holy Ghost is the Comforter, who is sent by Christ, and taught by Him and proclaims Him.
