I was converted by the classic Apologetic [Apostles of Denial, E.C. Gruss] from JW belief to Orthodox Trinitarianism, over 40 years ago. Since that time I’ve tried to convince other JW’s, and failed. They endlessly dispute every text I bring to support the Christian idea of God.
What if I have been doing this backwards? When a JW says, “the Trinity is not taught in the Bible,” perhaps I should respond: “what is? What is your concept of God.”
Ironically enough, for a group so invested in claiming Christians got their ideas from pagans, The JW’s believe Jehovah God is the biggest “spirit body” on top of something like a pagan Greek Parthenon of “Elohim”, and like them not omnipresent. Although Almighty, infinite in power unlike the angels, He lives in a “spirit-body” just like them.
In between God the biggest “spirit” in the Parthenon and the smaller “angel spirits”, is the arch-angel Jesus (a.k.a. Michael)—unlike them Jesus is an “a-god”. Above all other angel “Elohim” “sons of God”, but below their Creator Jehovah God. They all live spatially in a place called “heaven:
“While there are physical bodies visible and palpable, there are also spiritual bodies, invisible to human eyes and entirely beyond human senses. (1 Cor. 15:44) The bodies of spiritual persons (God, Christ, the angels) are glorious…The true God is not omnipresent.”–Aid To Bible Understanding, p. 247, 665 (Watchtower Bible & Tract Society, 1971)
Perhaps we would have more success demanding they prove from the scriptures their odd “pagan” view of a finite God?
Then the “shoe” is on the other foot, their proofs are being contradicted.
Whereas before, they ignored our “proofs”, they can’t ignore how their “proofs” didn’t hold up to scrutiny.
