190616 Sermon for Trinity Sunday The word “Trinity” or “triune” is two words put together into one. “Tri” means three—as in triangle or tricycle. “Une” is the other word, which means one—as in the card game Uno. So “Tri-une” is an adjective that means “three-one-ness.” The Triune God is the God who is three-one. The Holy Trinity is another name for the one true God alongside other names like Elohim, Jahweh, the Lord, Father, Son, and Holy Spirit.The word “Trinity” does not appear in the Scriptures. It is a word that was invented later by teachers who wanted to describe what the Bible says about God. Some people get unnecessarily upset by the absence of this word and think that it is wrong to use it. But it is not wrong to make up new words in order to describe what the Bible teaches. For example, another word that does not appear in the Bible is the word “sacrament,” which means “a holy thing.” Christians use the word to describe those things which Jesus instituted for the communication of forgiveness and salvation. The sacrament of Baptism and the sacrament of the altar are both holy things that communicate God’s grace. The word “sacrament” is a way to speak about both at the same time. We are free to use it or not use it, but we should not say that it is wrong to use the word.The same thing is true with the word “Trinity” or “Triune.” It is not absolutely necessary to use the word. We can use it or not use it. But we are not free to discard the thoughts that are behind the word, because the thoughts behind it are exactly what the Bible teaches. God being three in one and one in three is not an invention by any man. It is who God is. It is the way that he reveals himself to us in his word. Both his oneness, as well as the persons of the Trinity being distinct, is the way that the Bible speaks about God. For his oneness, consider this passage in Deuteronomy: “Hear, O Israel, the Lord your God is one.” This is a truth that is eternal. There are not many gods. There are not three gods. There is only one God. In our Old Testament reading where Isaiah sees the glory of the Lord in the Temple, he did not see many gods or three gods, but only one God.Then, on the other hand, we have so very many passages that speak of the Father, the Son, and the Holy Spirit. Think back on the past 5 or 6 weeks worth of Gospel readings that we have had. In these readings from John’s Gospel we’ve heard about the Father, the Son, and the Holy Spirit, and the relationships that exist between them. The Son will send the Holy Spirit, the comforter, when he has ascended into heaven. Jesus says that he will not ask the Father on our behalf, but you yourself will ask the Father, because the Father loves you because you believe that Jesus has been sent by him. Our Gospel reading today, perhaps the best known Bible passage that exists, distinguishes between the Father, who is often called simply God, and the Son who is Jesus: “God loved the world in this way, that he sent his only-begotten Son, that whoever believes in him shall not perish but have eternal life.” And then there are all the blessings and benedictions that are scattered throughout St. Paul’s epistles. We use one of those regularly that goes like this: “The grace of our Lord Jesus Christ, the love of God, and the communion of the Holy Spirit, be with you all.”And so we have two things that the Bible says about God. It says that God is one. It says that God is the Father, the Son, and the Holy Spirit, or that there are three distinct persons. The words “Trinity” or “Triune” is nothing other than shorthand for what the Bible teaches: three/one; one/three. It is false and blasphemous to say that there are more or other gods besides the One and Only true God. It is also false and blasphemous to deny what the Bible says about that one God—that the Father, the Son, and the Holy Spirit are distinct—and yet, though they are distinct, there are not th
