The text this morning is from the Acts of the Apostles, the second chapter:
But Peter, standing with the eleven, lifted up his voice and addressed them:
“Men of Israel, hear these words: Jesus of Nazareth, a man attested to you by God with mighty works and wonders and signs that God did through him in your midst, as you yourselves know— this Jesus, delivered up according to the definite plan and foreknowledge of God, you crucified and killed by the hands of lawless men. God raised him up, loosing the pangs of death, because it was not possible for him to be held by it. …This Jesus God raised up, and of that we all are witnesses. Being therefore exalted at the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this that you yourselves are seeing and hearing. For David did not ascend into the heavens, but he himself says, “ ‘The Lord said to my Lord, “Sit at my right hand, until I make your enemies your footstool.” ’ Let all the house of Israel therefore know for certain that God has made him both Lord and Christ, this Jesus whom you crucified.”
Thus far the text.
My dear friends in Christ,
This Holy Trinity Sunday, the Church throughout the world contemplates who our God is and what He has revealed about Himself. Our language doesn’t really even do our God justice, for there is no word in the English language that can apply to God, describing both His plurality of persons, three, the Father, the Son, and the Holy Spirit, and His unity, being one God. Even the pronouns get confused. His plurality, speaking of the three but referring to one, His unity, speaking of the one but referring to the multiple. There is no word that can do this, except one: the word, “Trinity.”
This word is a combination of two words, in essence, tri, referring to the three, and unity, referring to the one. Three persons, yet one God. Not three Gods. Not one person with different modes. Not an old God and two new Gods. One God. Three persons.
