John 3:1-17; Romans 11:33-36; Isaiah 6:1-7
In the Name of the Father and of the + Son and of the Holy Spirit.
The Holy Trinity is the greatest mystery of the Christian faith. And yet, belief in the Holy Trinity is necessary to salvation. One cannot be a Christian and deny the Holy Trinity. For to deny the Holy Trinity is to deny that, together with the Father, the Son and the Holy Spirit are also, and at the same time, God. To deny the Holy Trinity is to deny that Jesus is the Son of God, true God and true man, and therefore to deny that Jesus Christ is the Savior and Redeemer of all mankind.
To say that the Holy Trinity is a mystery is not to say that God cannot be known at all, or that He has left us in utter darkness. Rather, it is to confess that He cannot be fully explained or comprehended by human reason. The mystery of the Holy Trinity is beyond our understanding, yet not beyond our knowing. For the nature of a mystery is not to shut you out, but to draw you in, deeper and deeper into wonder, faith, worship, and trust. The more you hear, receive, and believe what God reveals, the more there is to ponder. Like standing at the shore of a vast ocean, you may know the water truly without ever exhausting its depths. So it is with the Holy Trinity.
This is why the Church confesses in the Athanasian Creed: “Whoever desires to be saved must, above all, hold the catholic faith.” And what is this catholic faith? “That we worship one God in Trinity and Trinity in Unity, neither confusing the persons nor dividing the substance.” What is necessary to confess has been revealed by God Himself. That means we may say only what God has said concerning Himself in His Word, and we may reject only what contradicts what He has revealed. The Holy Trinity is not an article of human speculation, philosophy, or reason. It is an article of faith. For the God who made heaven and earth, who created the mind itself, is before the human mind and beyond its limits. Yet He graciously reveals Himself, in creation, in His Word, and by His Spirit. And what God reveals must be received in faith.
Thus Jesus taught Nicodemus: “Unless one is born again he cannot see the kingdom of God,” and again, “Unless one is born of water and the Spirit, he cannot enter the kingdom of God.” Faith comes in much the same way as life itself. It is received, not earned. It is given, not seized. It is revealed, not reasoned into existence. The Holy Spirit calls, gathers, enlightens, sanctifies, and keeps people in the true faith where and when He pleases through the Means of Grace. Thus, you are the recipient of His gracious work, just as you are the recipient of life itself or the cooling breeze of the wind.
Jesus said to Nicodemus, “The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes.” You experience its effects even if you cannot comprehend its workings. So also with faith. Nicodemus was a learned and faithful man, a teacher of Israel. He could see with his own eyes that Jesus was a great rabbi sent from God. But his reason and observation could not yet comprehend that God was not merely with Jesus, but that Jesus Himself was God in human flesh, sent by the Father, upon whom the Spirit descended and remained.
And Nicodemus is not alone. Like Thomas. Like Peter. Like the Apostles. Like you and me. We are tempted to trust only what we can measure, prove, explain, and comprehend. We want God to conform Himself to our expectations and understanding. We seek signs that satisfy reason. But Jesus did not cast Nicodemus away. He did not shame him for his weakness. Rather, He invited him to receive, to receive the testimony of the Father, Son, and Holy Spirit in Word and truth. Faith in the Holy Trinity is a gift of grace, just as forgiveness is a gift of grace.
Isaiah knew this. When he beheld the Lord seated upon His throne, high and lifted up, surrounded by the seraphim crying, “Holy, holy, holy,” he did not stand confidently in his own righteousness. He cried out, “Woe is me! For I am lost.” And yet, the Lord did not destroy him. Instead, the seraph touched Isaiah’s lips with a burning coal from the altar and declared, “Your guilt is taken away, and your sin atoned for.” The holy God forgave the sinful man.
Nicodemus too received this gift, born again of water and the Spirit. And so have you. In Holy Baptism, your Triune God placed His Name upon you: Father, Son, and Holy Spirit. There He gave you new birth, forgiveness, faith, and eternal life. And all of this flows from the love of God revealed in Jesus Christ: “For God so loved the world, that He gave His only Son, that whoever believes in Him should not perish but have eternal life.”
Notice this well: God does not ask you to climb your way up to Him by reason or wisdom. He comes down to you in mercy. In today’s Collect we confessed this gift when we prayed: “Almighty and everlasting God, You have given us grace to acknowledge the glory of the eternal Trinity by the confession of a true faith and to worship the Unity in the power of the Divine Majesty.” You have been given grace to confess this faith. And we also prayed that God would keep us steadfast in it and defend us from all adversities. For this world constantly assaults the faith. Secular reason mocks what it cannot comprehend. Human wisdom dismisses what cannot be measured. False doctrine confuses God’s revelation.
Yet your Holy Triune God continues to reveal Himself to you. He has lifted up His only-begotten Son upon the cross that all who look upon Him in faith should not perish but have eternal life. Where human reason sees only a dying man upon a cross, faith beholds God Himself giving His life for sinners. Where reason sees only water, faith confesses Baptism as a lavish washing away of sins and new birth by the Holy Spirit. Where reason sees merely bread and wine, faith receives the very Body and Blood of Jesus Christ, true God and true man, given and shed for the forgiveness of sins, for the strengthening of faith, and for eternal life. For the God who is before all things, who made all things, sustains all things, and fills all things, the Holy Trinity, Father, Son, and Holy Spirit, is present even now to bless you with His mercy, forgiveness, and life.
Blessed be the Holy Trinity and the undivided Unity. Let us give glory to Him, for He has shown His mercy to us.
In the + Name of Jesus. Amen.
