Gnosticism
"Gnostics" are "those who claim to know." By contrast, "agnostics" are people who say that they don't know.
- Gnosticism (from gnostikos, "learned", from Greek: γνῶσις gnÅsis, knowledge) is a modern scholarly term for a set of religious beliefs and spiritual practices found among some early Christian and non-Christian groups called "gnostic" ("knowing") by Irenaeus and other early Christian leaders. In the past many scholars believed that gnosticism pre-dated Christianity, but now it is generally accepted that gnosticism developed into a coherent movement only in the second century CE.
