the Trinity
Today, some churches will observe Trinity Sunday as a way to remember and honor the Holy Trinity—our triune God consisting of three persons: Father, Son, and Holy Spirit. Three, and yet one God. The word Trinity is not found in the Bible. But the New Testament reveals a triune God (Matthew 3:16-17, Matthew 28:19; John 14:16; 1 Corinthians 6:11, 1 Corinthians 12:3-6; 2 Corinthians 13:14; Galatians 3:14; Hebrews 10:29; 1 Peter 1:2).
