This is a curious bit of news. I should introduce a definition first:
Ethicist: A high-brow intellectual who is paid to praise insanity, condemn good, and spew forth great quantities of shlock rhetoric. All this must be done with a maximum amount of grand standing. They are usually employed as professors who spend the majority of their classroom time trying to eliminate any sense of ethical or moral reasoning from their students.
It is right for the state department to try and engage in dialog with various religious groups. No doubt the CIA is doing this too along with a few other three letter agencies. The choice for this position is an Ethicist from Wesley Theological Seminary, Shaun Casey, thus, it is safe to say that the State Department has no intention of "Engagement" with Christians. Perhaps Muslims? Or maybe they have some other religion in mind?
