THE TRINITY
1. Core Meaning
The Trinity is the Christian doctrine that the one true God eternally exists as three distinct Persons—the Father, the Son, and the Holy Spirit—each fully God, equal in glory, united in essence, and inseparable in being.
It includes:
• One God in essence, nature, and being
• Three Persons—Father, Son, and Spirit
• Equality of deity, power, and glory
• Distinction of persons without division
• Unity of will, purpose, and action
• Eternal relationships within the Godhead
The Trinity is not a contradiction—it is the mystery of the one God who eternally exists in three Persons.
2. Biblical Foundations
Deuteronomy 6:4
“The LORD our God, the LORD is one.” (Summary: God is one in essence.)
Matthew 28:19
“Baptizing them in the name of the Father and of the Son and of the Holy Spirit.” (Summary: One name, three Persons.)
John 1:1–3
“The Word was with God, and the Word was God.” (Summary: The Son is distinct from the Father yet fully divine.)
2 Corinthians 13:14
“The grace of the Lord Jesus Christ… the love of God… the fellowship of the Holy Spirit.” (Summary: All three Persons act in unity toward believers.)
3. Theological Meaning
A. One Essence, Three Persons
God is one in being and three in personhood—united, equal, eternal.
B. The Father as Source
The Father begets the Son and sends the Spirit, yet is not greater in deity.
C. The Son as Eternal Word
The Son is eternally begotten, fully divine, and one with the Father.
D. The Spirit as Eternal Breath
The Spirit proceeds from the Father (and the Son), fully divine and personal.
E. Unity of Action
All divine works—creation, redemption, sanctification—are the work of the one Triune God.
