The Ecole Glossary contains short, 100-200 word glosses on topics relating to early Church history. These glosses are intimately linked to the Ecole Chronology and to each other. Because we plan to include several links in the glossary, links will refer to sites within the glossary or the chronology, unless specified otherwise, the one exception being the [DOC] symbol which points to a version of the document previously named somewhere on the internet beyond the Ecole Initiative.

The Ecole Initiative graciously welcomes corrections to any information contained in the Encyclopedia. Please send your comments to ecole@evansville.edu.
