The Christian Pentagram?
Christian Kabbalists who attempted to use Jewish mysticism to prove the divinity of Christ were especially enamored of the pentagram- to them, it symbolized Christ as the Holy Spirit manifest in the flesh. A favorite gematric feat was to add the Hebrew letter Shin (symbolizing fire and the holy spirit of Pentecost) to the Biblical four letter name of God (YHVH, most commonly pronounced 'Jehovah') yielding YHShVH- Y'heshua, or Jesus. (There is a secret biblical connection, as well, in the name of the Christian holiday of Pentecost- the day the Holy Spirit descended on the apostles of Jesus is one of many geometrical 'proofs' in the New Testament disguised as stories) There are many connections between the pentagram and Christianity. Before the cross, it was a preferred emblem to adorn the jewelry and amulets of early Christians (followed by an 'x' or a phoenix). It was associated with the five wounds of Christ, and because it could be drawn in one continuous movement of the pen, the Alpha and the Omega as one. It was also an expression of a secret Gnostic heresy, found hidden here and there throughout Christian history- a symbol of Isis/Venus as the secret goddess, the female principal. The most notable instance of this symbolism is in the Arthurian Grail romances, which are Gnostic and kabbalistic teachings disguised as tales of knightly quests. The small, five petaled flowers found in many Gothic cathedral ornamentation are not-so-secret pentagrams:
