"The best explanation of what Hymenaeus and Philetus were teaching is that they were pioneering a view which, as we shall see, was to become popular in other circles in due course, according to which "the resurrection" was now to be interpreted, not in terms of a future bodily hope after death, but purely and simply in terms of a spiritual experience which could be enjoyed during the present life. Certain people had had this experience; they were already, in this new metaphorical sense, "raised from the dead". It is not clear whether the two were encouraging others to have this experiences as well, or whether the point of their teaching was that if one was not already among those favored in this way there was now no hope. One way or another, they were drawing people away from what was being seen as mainstream Christian hope." (page 267-268)
