“A living, self-conscious being, as distinct from an animal or a thing; a moral agent” (Webster’s English Dictionary, 1913 ed)
“Definition of Personality. Personality exists where there is intelligence, mind, will, reason, individuality, self-consciousness, and self-determination. There must be not mere consciousness—for the beast has that—but self-consciousness. Nor is personality determination—for the beast has this, too, even though this determination be the result of influences from without—but self-determination, the power by which man from an act of his own free will determines his acts from within.
Neither corporeity nor substance, as we understand these words, are necessarily, if at all, involved in personality. There may be true personality without either or both of these.
(William Evans, The Great Doctrines of the Bible, p.22)
“PERSONALITY. In the first place, we endeavor to establish the personality of the Holy Spirit. By this we here mean that the Holy Spirit is a real being, possessing intelligence, and performing personal actions; not, however, a being distinct and separate in essence from the Father. We understand the one undivided essence or being in the Godhead to exist in three distinct persons—the Father, Son, and Holy Ghost. We would prove the personality of the Holy Ghost, 1. By the appellations; 2. By the actions; 3. By the honors, ascribed to him. If these be such as can only be applicable to a real and personal existence, then the inference will be clear that the Holy Spirit is a real and personal being, and not a mere abstract attribute, energy, or influence.”
(Thomas Ralston - Elements of Divinity, p.40)
Adopting Evans' definition, my
tentative conclusion is that God is a Person. God has "intelligence, mind, will, reason,
individuality, self-consciousness, and self-determination." Just like you and I do.
And it's the "individuality" feature that I want to focus on for the present. God is not
the same person as you or I. God is a
distinct Person from us, just as you and I and every other human walking the planet are distinct from each other. Each human is a unique individual and not the same "person" as another human. This "individuality" feature encapsulates the notion of "distinctiveness."
And the question becomes, is God
three distinct Persons, or only one? If
three, how are we to understand
God (as opposed to Father, Son and Holy Spirit) as a Person? The "individuality" component of Personhood would seem to preclude referring to God as
a Person -- presuming, of course, that we are bound by the axiom that there is only one God and no other gods.
Therein lies the problem in understanding the concept. For while each human shares the essence of "humanity" (we can define it later) and yet is a distinct "person" from every other human, the necessary corollary of this is that
there is more than one human. But we cannot say that each of Father, Son and Holy Spirit shares the essence of "deity" (we can define it later) while remaining a distinct "Person" from the other two -- yet
abandon the corollary of this that
there is more than one God. Stated another way, distinctiveness of individual members of a genus necessarily implies plurality within the genus.
To maintain monotheism and avoid tritheism, Trinitarians like myself (yes, I am one) either need to make an exception to this rule for God, or else must redefine "Person" in a way which accommodates both. I favor the latter approach.
By the way, Ralston's conclusion that the Holy Spirit is "not, however, a being
distinct and separate in essence from the Father" is at odds with Evans' definition of "Personality." If Ralston is right that the Holy Spirit is not "distinct" from the Father, then the Holy Spirit fails the "individuality" component of Personality announced by Evans.
