Christ, that is to say, the Second Person of the Triune Deity has always been Divine. It is Mormonism that teaches that Jesus Christ was a created being.

Christ, or rather the Second Person of the Triune Deity has never been "part" of Deity, which implies a division of Deity, but has always, Eternally been Fully Divine, with no division, nor separation of the Triune Deity.
