This is a post specifically regarding Munchy's comments on TD Jakes. This is what he said:
ok i agree that manifestations is not a good word used to describe the trinity.. but the church statement does not just end there, it also talks about Jesus Christ and the Holy Spirit in subsequent paragraphs. That's why although "manifestations" seems a wrong word to use, the subsequent paragraphs do clarify the issue. And I am definitely not prepared to call someone a heretic based on one word alone!
Manifestation is just "not a good word"? The church statement talks about Jesus Christ and the Holy Spirit and therefore the subsequent paragraphs clarify the issue? Let us analyze this in detail:
The word 'manifestation' when stated to define the Trinity has historically been associated with the Sabellian or modalist heresy in Church history. It has been resurrected by the Oneness Pentecostal cult, of which the United Pentecostal Church constitutes TD Jakes' background. So what does the word manifestation mean?
The word manifestation, when used to describe the relation between God the Father, God the Son and God the Holy Spirit, simply say that God was God the Father in creation. Then, at the Incarnation, part of God the Father 'morph' into God the Son in Jesus Christ. Following his death, God's spirit, which 'morph' to become God the Holy Spirit, came down from heaven to be present on this world.
Therefore, the word 'manifestation' is NOT just 'not a good word to use', anymore than the word 'evil' is NOT just 'not a good word to use' to describe God. T.D. Jakes denies the Trinity and thus blasphemes God. As such, he is not a Christian and needs to repent of his errors and turn to the Lord Jesus Christ who is the second person of the Trinity, not the 'Jesus' of his own making.
Now, we can look at the other aspects of Jakes' belief statement as stated on his church's website. We can then see whether, as Munchy says, 'subsequent paragraphs clarify the issue'.
Let's look at the 'fuller description of Jakes' doctrine of God':
God — There is one God, Creator of all things, infinitely perfect, and eternally existing in three Manifestations: Father, Son, and Holy Spirit.
Jesus Christ — Jesus Christ is true God and true man, having been conceived of the Holy Spirit and born of the virgin Mary. He died on the cross, the complete and final sacrifice for our sins according to the Scriptures. Further, He arose bodily from the dead, ascended into heaven, where, at the right hand of the Majesty on High, He is now our High Priest and Advocate.
The Holy Spirit — The ministry of the Holy Spirit is to glorify the Lord Jesus Christ and during this age, to convict men of sin, regenerate the believing sinner, indwell, guide, instruct, and empower the believer for godly living and service.
Well, I don't think I see any clarifying or modifying of his basic thesis regarding the oneness of God manifested in three different forms in the Bible. None of what Jakes says here change or alter (or 'clarify')his Sabellian heresy. In fact, judging by his association with the apostate Higher Ground Always Abounding Assembly which similarly embrace the Sabellian heresy, I shouldn't be surprised by his embrace of the modalist error.
Oh, regarding the condemning of people as heretics because of one word, I would like to put forward the same counter-example as stated above. If I said that God is evil, am I a heretic? If I say that Jesus became a sinner at the Cross, am I a heretic? Notice that they both revolve around single words: 'evil' and 'sinner'. I guess my point is proved by now.
