swaimj,
Let me develop my point a little more regarding the message of 2 Thessalonians.
Chapter 1 is essentially an account of Paul's thanksgiving for the God's using opposition to strengthen the Thess. faith.
Chapter 2 deals with Paul's command for the Thess. not to be deceived by bad eschatology, but to stand firm in what he had taught them before. That is the only command I see in the letter besides the command to separate. Whoops, almost forgot the command to pray in 3:1.
In chapter 3 Paul addresses the issue of separation from those who are being lazy. Now correct me if I'm wrong, because I don't have a Thess. commentary handy, but if I recall correctly, I believe it is considered likely that some in Thess. were selling their property, abandoning their jobs, and living it up because they thought Christ's return was immediately imminent.
Paul's admonishments about laziness and separation were closely tied to the immediate problem faced in chapter 2. The oral teaching he refers to in 3:6 probably points to the eschatology he says (in 2:5) that he had dealt with in person.
Even if my historical reconstruction is incorrect, I still don't see any broad application to all sorts of differences in doctrine or practice, and certainly not standards. 2 Thessalonians simply doesn't deal with a broad range of issues.
