Triune God-Father,Son Holy Ghost

Father, Son, and Holy Ghost...
The Bible says that there are three that bear record in heaven: the Father, the Word (Jesus Christ), and the Holy Ghost; and these three are one. (1 John 5:7).

"The Father and the Son and the Holy Spirit" are not names for different parts of God but one name for God because three persons exist in God as one entity.

They cannot be separate from one another. Each person is understood as having the identical essence or nature, not merely similar natures.

Christian doctrine: "The unity of Father, Son, and Holy Spirit are three persons in one Godhead." Dedicated Mennonites
Do believe this teaching.
The doctrine of the Trinity is considered to be one of the central Christian affirmations about God.

For there are three that bear record in heaven: the Father (God), the Word (Jesus), and the Holy Ghost, and these three are one.

The term "triune God" refers to the Christian doctrine of the Trinity, which describes God as one being existing in three distinct co-equal persons: the Father, the Son (Jesus Christ), and the Holy Spirit. This concept is a central belief of Christianity, emphasizing God's unity and the distinct roles of each person within the Godhead.

In Christian theology, the Trinity refers to one God in three persons: God the Father, God the Son (Jesus Christ), and God the Holy Spirit. Though all three are fully and equally God—eternal, omnipotent, and sharing the same divine nature—they have distinct roles or functions in relation to creation, salvation, and believers. Here's a basic breakdown:

#1. God the Father—The Creator and Sustainer.
#2. God the Son (Jesus Christ)—The Savior and Redeemer.
#3. God the Holy Spirit— God lives within each believer.

So, to be clear:
God the Father is the creator of the whole universe. He is almighty; He is omniscient.
God the Son (Jesus Christ) is the savior of those that believe in him and trust him.
God The Holy Spirit is the one that lives in a believing Christian. No one can come to Jesus
unless the Holy Spirit leads you and guides you.
