Uhm, define traditional christianity please.
The way he says it, is that my type of Christianity(honouring torah, law and prophets, and that Christ is not God, but the son of God and saviour of the world, who will give all dominion back to God so God can be all in all), will have the mark of God, and those who do not honour law torah and prophets(ie the law is done away with, it does not count for us, we're free from legalism), will be turned away by Jesus for He does not know them, because their lawlessness is the mark of the beast.
Plus, only a few will find the way to eternal life, and broad is the way that leads to damnation.
I think this view has a lot of credibility. Most plus point he has is that he uses the bible to explain the bible, and gives the jewish insight, which you need to interpret the bible correctly.
