w00 8/1 p. 6 Respect for Authority-Why Essential?
Hymenaeus and Philetus are mentioned as men who subverted the faith of some and whose empty speeches 'violated what is holy.' One of their assertions was that the resurrection had already taken place, evidently either a spiritual or a symbolic one, and therefore there was no further resurrection in the future under God's Kingdom.-2 Timothy 2:16-18.
Proclaimers, chap. 4 p. 34 The Great Apostasy DevelopsAs the first century progressed, divisive thinking spread like gangrene. (Compare 2 Timothy 2:17.) By about 51 C.E., some in Thessalonica were wrongly predicting that "the presence" of the Lord Jesus was imminent. (2 Thess. 2:1, 2) By about 55 C.E., some in Corinth had rejected the clear Christian teaching regarding the resurrection of the dead. (1 Cor. 15:12) About 65 C.E., others said that the resurrection had already taken place, it being of a symbolic kind that living Christians experience.-2 Tim. 2:16-18.
This view is pretty much in line with what other commentators have said. http://bible.cc/2_timothy/2-18.htm
