How does the Trinity relate to Christ as the eternal Word?

The Trinity is a central doctrine that reveals the nature of God as one Being in three distinct persons: the Father, the Son (who is the eternal Word), and the Holy Spirit. Each person is fully God, co-equal and co-eternal, which means that there is no hierarchy among them in terms of divine essence. This is critical for understanding the work of Christ in salvation; the Son submitted to the Father's will in the plan of salvation while still retaining His full divinity. This submission doesn't indicate inferiority but is an expression of the harmonious will within the Godhead, highlighting the unity and diversity of God's nature. This truth is foundational for grasping the fullness of the gospel.
