Ok, so this isn't actually an argument for prelacy per se--more a comment on an advantage the Episcopal churches seem to have over us Reformed folks--that is, the issue of names.
We Reformed folk seem to have a very narrow stock of possible church names--basically, some combination of Christ, Trinity, Covenant, and Reformed (or Reformation). That's really about all there is to work with, it seems. Now, allowing for up to two names per church, this allows us only 16 options to choose from (of which not all would really work well), plus a couple odds and ends. This kind of redundancy can lead to a great deal of confusion, even within the narrow Reformed world--"Wait, did you say you were from Covenant Reformed or Reformation Covenant? Oh, that explains the confusion--Covenant Reformed is in Maine, not Iowa!)
In my experience, though, the Episcopal churches prefer to draw from the riches of Church history and name their churches after any number of saints. St. Luke's, St. Mark's, St. John's, St. Bartholomew's, St. Stephen's, St. Thomas's, maybe even St. Bede's.
Why are we Reformed folk so averse to using saints' names in our churches? I assure you that if I ever start a church, it will not have the words "covenant" or "reformed" in it. *ducks and runs*
