With proper-noun naming (denominating) comes more of a sense of formal organization, as detailed in the last post here. A denominated group may manifest unwillingness to have its name questioned. This was my experience when teaching a junior high Bible class as a young instructor in a Christian academy. I had the one Bible class (along with band and choir classes I taught) and took them all very seriously; the worksheet below is one assignment I devised for the students.
One would think that I’d’ve been applauded for asking the 8th graders to “go back to the Bible” to find various descriptions and labels for the church. Not so. The Bible class was actually taken away from me midstream. In my view (obviously not that of a certain school administrator and, I suspect, some others with clout), this was an improper riddance of me as a Bible teacher. More important, it was an improper pushing-aside of some very simple, yet significant, facts from scripture.
It is hurtful to be judged unworthy by the group from which you originate when you are only trying to bring growth. Although I was over those particular wounds within a couple years, in a very real sense, a general anxiety in connection with potentially being judged improperly has remained with me.
Relatively consistently for a quarter-century now, I have been seriously interested in undenominational Christianity, relegating group names to a low berth if proper names must be used at all. This is a small part of restoring and unifying, but it is a part nonetheless.
