Christian theosophy

Esoteric Christianity (Hermetic Christianity) is an ensemble of spiritual currents which regard Christianity as a mystery religion, and profess the existence and possession of certain esoteric doctrines or practices of which the public is unaware (or even to which they may be denied access) but which are understood by a small group of people.

These spiritual currents share some common denominators, such as heterodox or heretical Christian theology; the canonical gospels, various apocalyptic literature, and some New Testament apocrypha as sacred texts; and disciplina arcani, a supposed oral tradition from the Twelve Apostles containing esoteric teachings of Jesus the Christ.

Early Christians used the Greek word μυστήριον (mysterion) to describe the Christian Mystery. The Old Testament versions use the word mysterion as an equivalent to the Hebrew sôd, "secret" (Proverbs 20:19). In the New Testament the word mystery is applied ordinarily to the sublime revelation of the Gospel (Matthew 13:11; Colossians 2:2; 1 Timothy 3:9; 1 Corinthians 15:51), and to the Incarnation and life of the Saviour and his manifestation by the preaching of the Apostles (Romans 16:25; Ephesians 3:4; 6:19; Colossians 1:26; 4:3).

The word "mysticism" is derived from the Greek μυω, meaning "to conceal", and its derivative μυστικός, mystikos, meaning 'an initiate'. In the Hellenistic world, 'mystical' referred to "secret" religious rituals. The use of the word lacked any direct references to the transcendental. A "mystikos" was an initiate of a mystery religion.
