This sermon for Trinity Sunday discusses the works of God and their attribution to the Persons of God. To the Father is ascribed Creation, although the other persons are involved; similarly the work of Redemption is ascribed to the Son although the Father and the Spirit each have their part to play. And the Work of giving life and faith to the believer is the work of the Spirit, sent by Father and the Son. To this message is added the Athanasian Creed, a clear statement of who God is and who Christ is.  The Te Deum hymn of Empress Maria Theresa , "Holy God We Praise Thy Name," completes this program.
