I've provided a number of posts on 2 Thessalonians 2:15 that address its abuse by those whom I refer to as "traditionists."
1. Opening Post
2. Response to Comments by Reginald (Roman Catholic)
3. Additional Clarification
4. Response to Comments by "Orthodox" (Eastern Orthodox)
This post serves as an index post. Accordingly, I will plan to update it from time to time, in the unlikely event that new arguments in defense of the typical misuse of 2 Thessalonians 2:15 are presented. Eventually I expect to date-bump this post back in time so as to make it fit with my organizational scheme for this blog.
