Is there a name for the belief that Christ in heaven no longer has a human body or nature?

I have encountered a guy online who insists that Christ no longer has human flesh or a human body. Sometimes he seems to say that Christ no longer has a human nature but I haven't been able to pin him down on that. This doesn't sound like any of the major heresies I'm familiar with from the first five centuries of the church and I'm wondering if it has a name; I haven't been able to find one for this and would like to research it -- and having a name would help. For what it's worth, one of his arguments is that the phrase "in the days of His flesh" in Hebrews indicates that Christ no longer has flesh. edit: This guy affirms that salvation was achieved on the Cross, and agrees that physical existence is good, but seems to regard Christ's human body as a sort of temporary tool for accomplishing redemption and thus no longer necessary. He also gives the impression that having a human body in heaven would be degrading.
