UPDATE: Since I first posted, they've posted an addendum. Which in my view is so snide as to make things worse.
UPDATE 2: Ouch! Hugh Hewitt's site contrasts CPT with St. Paul, who wrote:
Greet Priscilla and Aquila, my fellow workers in Christ Jesus. They risked their lives for me. Not only I but all the churches of the Gentiles are grateful to them. --Romans 16:3-4
