The Term
Trinity
(TRIN-uh-tee)
The Definition
Merriam-Webster: “The unity of Father, Son, and Holy Spirit as three persons in one Godhead.”
FTG Expanded Explanation:
The Trinity is the biblical doctrine that God is one in essence and three in persons: Father, Son, and Holy Spirit. Each person is fully God, equal in power and glory, yet distinct in role and relationship. This is not three gods, nor one God appearing in three modes, but one God eternally existing in three persons.
The Biblical Connection
Matthew 28:19 – “Baptizing them in the name of the Father and the Son and the Holy Spirit.”
2 Corinthians 13:14 – “The grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit, be with you all.”
Matthew 3:16-17 – “After being baptized, Jesus came up immediately from the water; and behold, the heavens were opened, and he saw the Spirit of God descending as a dove and lighting on Him, and behold, a voice out of the heavens said, ‘This is My beloved Son, in whom I am well-pleased.’”
Used in an Everyday Conversation
“The Trinity is a divine paradox. The Bible teaches that God is one, yet revealed as three persons. The Father, Son, and Holy Spirit are perfectly united and eternal.”
“At Jesus’ baptism in Matthew 3:16–17, all three persons are present. The Father is speaking, the Son is being baptized, and the Spirit descending.”
“R. C. Sproul once said, ‘The Trinity is one God in three persons. This is not contradictory, but it is beyond full human comprehension.’”
