Here's one interpretation from a preterist perceptive.

The Man of Lawlessness: A Preteristic Postmillennial Interpretation of 2 Thessalonians 2 by Dr. Kenneth L. Gentry, Jr.

I personally have not worked through all the implications of 2 Thess. 2.

The Man of Lawlessness is Nero Caesar, who also is the Beast of Revelation

So just when did Cesar Nero sit in the Temple in Jerusalem????
