In many spiritual traditions there is a common practice of receiving a new name. What is this, and what does it have to do with mysticism?
The ritual practice of anointing makes the person that is anointed an "Anointed One," which is what the word Christ literally means, and by derivation is what being a Christian means. Cyril of Jerusalem in the fourth century noted of those who had been baptized and anointed, "You have been made Christs, by receiving the anti-type [symbol] of the Holy Spirit [the oil]" (Catecheses 21.1). Receiving the chrism they are ritualistically made Christs, being clothed in that Name and Identity, taking it upon themselves in actual fact as their own Eternal Identity, their True Name/Self.
