The Christian belief that God is three Persons in one God is called?

• A. Monotheism
• B. Incarnation
• C. Trinity
• D. Predestination

Answer: (C)

The Trinity is the Christian doctrine that there is one God who exists as three Persons: Father, Son, and Holy Spirit. Each Person is fully God, sharing the same divine essence, yet they are distinct in personal relationship. This means there is one God, not three gods, but within that one God there are three interrelated centers of being and action. The Father, Son, and Holy Spirit work together in creation, redemption, and sustaining the world, and the New Testament ways of speaking about God often name all three in connection with baptism and Jesus’ teaching, showing both unity and distinction.

Understanding this helps distinguish it from related ideas. Incarnation refers to God becoming human in Jesus, which is about Jesus’ person and mission rather than the nature of God’s being. Predestination concerns God’s sovereign plan for salvation, not how God is one being in three persons. Monotheism affirms one God, which is true in Christianity, but it doesn’t by itself explain how one God can exist as Father, Son, and Holy Spirit.
