Glossary of Christianity Terms

Christianity is far from being the oldest religion or the one with the most jargon, but in its relatively short span of existence has accumulated a wide variety of terms. Not all of these are unique to Christianity, but they are often heard in explicitly Christian contexts, ‘disciple’ being a good example. This glossary of Christianity terms is far from exhaustive, but it should be a good start.
