The major problem with Donald Trump’s use of language is not so much what he literally says, but with what his utterances reveal about who and what he really is.
Here is my thought on this question: Trump is the Antichrist and his discourse can only be properly understood from that perspective. Remember: I am a linguistic scientist so I know about arcana of this kind.
The notion of the Antichrist is one of the murkiest, yet scariest and therefore most potent, narratives comprising the discourse of Christianity. There are several versions of the story: where he comes from, what role he plays, and how his existence fits into the larger understanding of Christianity.
