Implicit in the Old Testament is the Triune identity of God, that He is One God in Three Persons (Father, Son, and Holy Spirit). Dr. Zeile's message shows how this identity is implicit in Isaiah 48 :16 where the Servant of the Lord declares that He is sent by Jehovah with the Spirit. This meditation for the Festival of the Most Holy Trinity is fittingly accompanied by the Te Deum Laudamus from Matins, the Litany, and classic hymns, "Praise the Almighty , My Soul Adore Him,' and Luther's "In Peace and Joy I Now Depart," based on the Nunc Dimittis.
