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.

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.
