This is a very important message for those who do not know God., page-54

"That's a lot of garble to exhibit" -> Man up and prove your case with the Bible.

" what trinity doctrine is all about"

Jesus knocks that father of lies creation on the head in one swoop following;

This now is the eternal life that they should know You (Father) the ONLY TRUE God and whom you have sent, Jesus Christ.
(He independently of himself, defines the Father as the only true God when he was here).

He also quotes the OT backing this -> Hear, Israel: Yehowah our God is ONE Yehowah.

Then Paul also sticks it up ya lol.
1 Cor 8:6 - But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, through whom are all things, and we through him.
