What is the Trinity?
The Trinity is the Christian teaching that there is one God who eternally exists as three persons — Father, Son, and Holy Spirit. Not three gods, and not one person in three modes, but one God in three persons.
The Bible affirms that there is only one God, yet it speaks of the Father as God, Jesus the Son as God, and the Holy Spirit as God — each distinct, all one being.
The word “Trinity” isn’t in the Bible, but the teaching draws together what Scripture says. It appears, for example, when Jesus tells his followers to baptize “in the name of the Father and of the Son and of the Holy Spirit” (Matthew 28:19).
It is a mystery beyond full comprehension, but it lies at the heart of the Christian understanding of God as eternally relational and loving.
