I know a lot of discussion has surrounded the heresy of Modalism lately due to T.D. Jakes’s star appearance on the seeker-sensitive sitcom known as the Elephant Room 2. There is another rank heresy that challenges the very nature of God which is just as bad as Modalism. Those who teach that Jesus is not the eternal Son of God are also attacking the very core nature of our Lord. The truth is that God never changes and He has existed eternally as The Father, Son and Holy Spirit three but yet One(Hebrews 13:8).
It was deeply encouraging when John MacArthur repented of his error of denying the eternal Sonship. See: Reexamining the Eternal Sonship of Christ
I personally believe denying Christ’s eternal relationship within the Trinity is as deadly as what Modalism teaches. I would encourage all my readers to ponder what I have written today.
