No trinity. God uses language we can understand. A father is older than his son. The Son came forth (begotten) from the Father. Together they send out their Spirit, i.e. the living water flowing from the throne of God and of the Lamb in Revelation 22:1.

Jesus is the Comforter and the Spirit, He knows what we go through. The "holy ghost" of a supposed "trinity" doesn't know what it's like to be a human... but the Son does, the Son of man, Jesus Christ, the one whose "goings-forth have been from of old, from everlasting".

After speaking about the Comforter in John 14, all through John 17 Jesus prayed about His Father and Himself - no separate "holy spirit" is mentioned. Jesus is our Holy Spirit.

Christianity has virtually no knowledge of who their God is. Very sad.
