Ever wondered what in the world a narthex or purificator might be? 
The Episcopal Diocese of Dallas has a great glossary of Episcopal Church terms... check it out below..

From their website......The long history of the Church has led to the accumulation of many terms that one seldom if ever otherwise hears. Some members of the church delight in using these words, but they really do not mean to confound you by doing so: many of them simply have no satisfactory substitute. The good news is that once you’ve learned a few of them, you can join in the fun as well! The following list should answer all but the most obscure questions, but if you really want to get into the most impenetrable corners with an exhaustive glossary, we recommend that you visit the Episcopal Church site.
