Reserved for Orthodox?
Let me level my vote against reserving this category solely for Orthodox bishops. Why? Well, while we certainly may end up discriminating between heterodox and Orthodox bishops of our own day, we would also have to take all of the past's heretical bishops out of the category, too, which I think becomes unhelpful and confusing in terms of sorting and understanding history.
The individual articles make it clear what a particular bishop's allegiance is. I don't think anyone will look at Category:Bishops, see someone like John Paul II or Nestorius in there, and thus think, "Ah, this must be an Orthodox bishop." So, my vote is to leave those folks in, make it clear in their articles who they are, and add sub-categories to clearly subcategorizable folks (such as non-Chalcedonians). I'm much more hesitant to consign to sub-categories bishops in churches whose churches are simply on the fringe or out of communion, etc. Again, we just make sure that the articles are clear. —Dcn.
