A rather fun conversation before lunch involved trying to explain various senses of the term “orthodox” which is beginning to do the rounds of some quarters of the communion. Properly, of course, it refers to the Holy Orthodox Churches, whose agreed designation it has been since the 11th Century at least. Now it’s beginning to be used with a slight curl of the upper lip as a badge of rigid right wing conformity to type.
With all such terms, even “Christian” or “Methodist,” you have to ask “who says you’re / they’re one of those?” If the only answer is, “I do, along with my close compadres,” you can be pretty sure you're being sold a pup. Similarly there are words like “revisionist” which seem to play the same role in right wing parlance that “fundamentalist” does in left wing banter. You can pretty much bet your bottom dollar that they are merely hostile name-calling, no more. If you hear them used, you can just ask the person using them to put their brain into gear and try and articulate what or who they really mean, and on what basis.
The only way to stay sane and be courteous is to pass a rigid self-denying ordinance that “I will only use of other people designations they use of themselves.” This could helpfully be supplemented by a simple Bart Simpson Blackboard resolution: “I will not hi-jack other people’s labels to spite my enemies.” If all that came out of this Lambeth were a few people resolving along these lines, that would be grief to the weasels, and joy to the world.
