The Anglican Church has existed for many centuries, and many of the concepts,
objects, and rituals have not changed a great deal since the days of the
12 Apostles. The language of our everyday world has evolved, but the language
of our church is very old. As a result, many church words are unfamiliar
to modern people.
There are some books in print that explain the vocabulary of the Anglican
church. We like Church
Words: Origins and Meanings by Stephen E. Moore, and A
New Dictionary for Episcopalians, by The Rev. John N. Wall, Jr.
For a richer online dictionary, we like the online glossary maintained by St Paul's Church in Augusta, Georgia, USA, though its type size is so small that we can hardly read it. The Dictionary of Episcopal Things maintained at the University of the South is also quite well done.
