What is the Trinity in simple terms?
The Trinity is the Christian confession that there is one God who exists eternally as three distinct persons: Father, Son, and Holy Spirit. Not three Gods, not one person playing three roles — one God, three persons.
The Bible insists there is only one God (Deuteronomy 6:4) — and reveals three persons each treated as fully God: the Father (1 Corinthians 8:6), the Son (John 1:1; 20:28), the Spirit (Acts 5:3–4).
The Trinity is not a contradiction — God is one in being and three in person. It is not three plus one equals one in the same category.
It is the most beautiful Christian doctrine. God is eternally love, eternally relational — Father loving Son in the Spirit. Salvation invites us into that love.
