Trinity Sunday Bible Study

Trinity Sunday is a special day in the Christian church when we celebrate the mystery of the Holy Trinity. The Trinity is the belief that there is one God who exists in three persons: the Father, the Son, and the Holy Spirit. This doctrine is not explicitly stated in the Bible, but it is implied in many passages.

Genesis 1:1-2:4a

The first book of the Bible, Genesis, tells the story of creation. In the opening verses, we read that “in the beginning, God created the heavens and the earth.” This verse tells us that God is the creator of all things. It also tells us that God is one.

Psalm 8

Psalm 8 is a song of praise to God. In this psalm, the psalmist marvels at the majesty of God and the beauty of creation. The psalmist also acknowledges that God is the creator of all things and that we are all dependent on him.

2 Corinthians 13:11-13

In this passage, Paul writes to the church in Corinth and reminds them of the love of God. He also prays that the grace of the Lord Jesus Christ, the love of God, and the fellowship of the Holy Spirit would be with them all.

Matthew 28:16-20

This passage is known as the Great Commission. In this passage, Jesus gives his disciples the authority to go and make disciples of all nations. He also promises to be with them always, even to the end of the age.

Discussion Questions

  • What do you learn about the Trinity from these passages?
  • How does the Trinity impact your understanding of God?
  • How can you live out your faith in the Trinity?


The Trinity is a mystery that we will never fully understand. However, we can learn a great deal about God by studying these passages. The Trinity teaches us that God is one, but he also exists in three persons. This mystery reminds us that God is beyond our understanding, but he is also loving and personal. The Trinity also gives us hope, because it reminds us that we are never alone. God is always with us, through the power of the Holy Spirit.

Closing Prayer

Dear God,

We thank you for the mystery of the Trinity. We pray that you would help us to understand your love and grace more fully. We also pray that you would give us the courage to live out our faith in the Trinity, wherever we go.

In Jesus’ name, amen.
