Confessing the Holy Trinity

The Athanasian Creed, which was written by an anonymous author in the fifth century, is the Church’s confession of the Holy Trinity. On Trinity Sunday, the Church proclaims the Christian faith through the words of the Athanasian Creed.

“The Athanasian Creed declares that its teachings concerning the Holy Trinity and our Lord’s incarnation are “the catholic faith.” In other words, this is what the true Church of all times and all places has confessed. More than fifteen centuries later, the Church continues to confess this truth, confident that the triune God, Father, Son, and Holy Spirit, has given Himself for our salvation.”

Liturgical colors for Trinity Sunday

The altar will be adorned with white, which is the color of purity and completeness. This color assists in bearing the message that “though your sins be as scarlet, they shall be white as snow.” Christ’s triumph from the grave on Resurrection Day is the cause for our rejoicing. His purity before his Father becomes our purity. White reinforces that message of joy.

Lectionary summary

The Glory of the LORD of Hosts Shines in Mercy, Forgiveness and Salvation

When Isaiah “saw the Lord sitting upon a throne, high and lifted up,” he cried out and confessed that he was “a man of unclean lips.” If even the holy angels cover their faces in the presence of “the King, the LORD of hosts,” how can sinful humans stand before Him (Is. 6:1–5)? Yet, the glory of the Lord is saving grace, and with “a burning coal” from the altar the angel touched Isaiah’s lips, removing his guilt (Is. 6:6–7). Likewise, from the altar of Christ’s cross, by the ministry of the Gospel, “the whole earth is full of his glory” (Is. 6:3). For He was crucified, died and was buried, “according to the definite plan and foreknowledge of God,” and God “raised him up, loosing the pangs of death” (Acts 2:23–24). He “received from the Father the promise of the Holy Spirit” (Acts 2:33), and He raises up the fallen world by pouring out His life-giving Spirit upon sinners through His earthly Means of Grace. To give this saving gift, God sent His Son into the world, “that whoever believes in him should not perish but have eternal life” (John 3:16–17).

Lectionary summary

The Holy Trinity Reveals Himself to Sinners

When Isaiah beheld the glory of the Lord, he cried out “Woe is me!” For the sinner cannot stand in the presence of a holy God and live (Is. 6:1–7). But God the Father lifted up His Son Jesus for us on the cross, that whoever believes in Him should not perish but have eternal life. This eternal life of Christ is given us according to the Holy Spirit’s good pleasure in Baptism. “Unless one is born [again] of water and the Spirit, he cannot enter the kingdom of God” (John 3:5). To sinners in fear of death, the messengers of God place on our lips the living body and blood of Christ and speak His words of absolution, “Your guilt is taken away, and your sin atoned for” (Is. 6:7). Having received forgiveness and life from the Father through the Son by the Holy Spirit, we join with the angels in praising the blessed Trinity, “Holy, holy, holy is the LORD of hosts!” (Is. 6:3). “For from Him and through Him and to Him are all things. To Him be glory forever. Amen” (Rom. 11:33–36).
