Am I a heretic?

I'm reading an article at the moment on the Cambridge Platonist Henry More (I still haven't found that action figure, by the way). The author, John Henry, writes that one of More's motivations for developing his concept of the soul was to defeat (or convert) mortalists. Henry writes:

As is well know mortalism was an extremely prevalent heterodoxy in seventeenth-century England, and Henry More frequently wrote against it. Mortalists responded to the problem of soul-body interaction by taking a monistic view of the person. On death the person was held to lie 'asleep' in the grave until the general Resurrection on the Last Day. At the Resurrection, it was held, the whole person (body and soul, if they can be meaningfully distinguished) would be resuscitated by God.

I don't think the Bible tells us enough about this topic to make any absolute pronouncements, but I've thought for a while that this viewpoint makes sense and seems to fit with what the Bible does say. Except for the "resuscitation" bit. We will have a new body, not the old one pacthed up a bit. I think.

I've read about mortalism (also known as psychopannychism) before in an article about Isaac Newton, who apparently held this view. The other author (James Force, I think, or Richard Popkin) called it a "heresy." So... am I a heretic??
