Person (Latin, persona, a mask; personwtus, one who wears a mask, an actor).
A person is one who impersonates a character. Shakespeare says, All the worlds a stage, and all the men and women merely players or persons. When we speak of the person of the Deity we mean the same thing, the character represented, as that of the Father, or that of the Son, or that of the Holy Ghost. There is no more notion of corporeality connected with the word than there is any assumption of the body of Hamlet when an actor impersonates that character.
