Exposing heretics and those who are working in opposition is sometimes seen as an unbiblical activity. To some, it even seems to be a very unloving thing to do, especially when names are mentioned.

The Apostle Paul felt it necessary to point out those he wished his readers to be made aware of and avoid. Here is a list of six people named in 2 Timothy:
1) Phygellus (2 Tim 1:15)
2) Hermogenes (2 Tim 1:15)
3) Hymenaeus (2 Tim 2:17)
4) Philetus (2 Tim 2:17)
5) Demas 4:10 (apostate) (2 Tim 4:10)
6) Alexander the Coppersmith (2 Tim 4:14)

7) Jannes (2 Tim 3:8)
8) Jambres (2 Tim 3:8)
