Not talking about people here; instead, I thought we'd think in terms of words/concepts that may be ready to be retired (honorably or otherwise) from service. We've had some discussion already about whether "church" might fit into this category; "Christian" is another possibility, as is "patriarchy" (all for different reasons, however). Let's focus on important words within the context of the communities of Messiah's followers. Let's not chase words that we find merely annoying, but words which, whatever their past usefulness may have been, have now reached a place where they are actually counterproductive to the present progress of God's kingdom (as best we understand it).
So here's what you do: propose a word that you feel has outlived its usefulness. Briefly explain why you think this is the case, and, most importantly, propose/suggest a new word to take its place. Feel free to coin a new word altogether if you must!
