The Trinity: 17 Verses about the ‘Oneness’ of God

Understanding the Trinity—one God in three persons (Father, Son, and Spirit)—takes us into deep theological waters, where the simplest math fails us: 1 + 1 + 1 = 1. 

Even though the word “Trinity” never appears in the Bible, God reveals himself throughout Scripture as one being (Deut 6:4, John 10:30) in three persons (Gen 1:2; Matt 3:16–17, 1 Pet 1:2). While we can’t find answers to every question about the Trinity, we can grow in our love for God by searching Scripture to discover how he reveals himself to us.

Here are 17 verses about the Trinity, organized by topic: 

  • The Trinity exists in 3 persons
  • Each person of the Trinity is God
  • There is only one God

The Trinity exists in 3 persons

And when Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him; and behold, a voice from heaven said, “This is my beloved Son, with whom I am well pleased.”
