My interest in the concept of personhood is multifarious as I believe it will help in building a proper theology for various elements in our society and Church. In reading Vincent of Lerins, I happened upon this chapter from his Commonitory (ch14). Unlike Tertullian’s less defined, or unrefined, persona in describing the Father, Son, and Spirit, Vincent (a proper Saint) uses persona differently.
BUT inasmuch as we often use the term person, and say that GOD in a person was made man, we must take very great care, lest we seem to say that GOD the WORD took on Him our properties merely in the way of imitative acting; and that whatever made up His human conversation was done by Him not as a true man, but in adumbration, after the manner of theatres, where one individual represents in quick succession several personages, of which no one is his own.
Sed cum personam sæpius nominamus et dicimus, quod Deus per personam homo factus sit, vehementer verendum est, ne hoc dicere videamur, quod Deus Verbum sola imitatione actionis, quæ sunt nostra susceperit, et quidquid illud est conversationis humanæ, quasi adumbratus, non quasi verus homo fecerit: sicut in theatris fieri solet, ubi unus plures effingit repente personas, quarum ipse nulla est.
But the Catholic faith says that the WORD of GOD was so made man as to take on Him our properties, not fallaciously and in show, but truly and actually; and to deport Himself as a man, not as one who imitates the doings of another, but rather as in his own character; and altogether to be what He represented, just as we ourselves, in that we speak, know, live, subsist, do not imitate men, but are such…So also GOD the WORD, in assuming and having flesh, in speaking, doing and suffering in the flesh, yet without any corruption of His nature, deigned even to go so far as not to imitate or represent a perfect man, but to exhibit Himself as such; so as not merely to be seen or to be thought a true man but to be such, and to subsist as such.
Catholica vero fides ita Verbum Dei hominem factum esse dicit, ut quæ nostra sunt, non fallaciter et adumbrate, sed vere expresseque susciperet; et quæ erant humana, non quasi aliena imitaretur, sed potius ut sua gereret: et prorsus quod agebat, hoc etiam esset, quod agebat, is esset. Sicut ipsi nos quoque in eo quod loquimur, sapimus, vivimus, subsistimus, non imitamur homines, sed sumus….ta etiam Deus Verbum, adsumendo et habendo carnem, loquendo, faciendo, patiendo per carnem, sine ulla tamen suæ corruptione naturæ hoc omnino præstare dignatus est, ut hominem perfectum non imitaretur aut fingeret, sed exhiberet: ut homo verus non videretur aut putaretur, sed esset atque subsisteret.
The idea of personhood, then, as showed to us via the Holy Trinity, is that to be a person requires something more than being human.
Note, Christ could still have been a human without being a person. What makes him a person is his life, not that he was born a human. Perhaps he could have grown up completely free from sin and desire, without the need to eat or expel the wastes of eating. Perhaps he could have simply been born a human male, or dropped from the sky as such. Yet, Vincent reminds us that he subsisted as a person.
If Jesus subsisted as a person, that means he was afforded the ability to be wrong and to be right, to love (maybe lust), to be tempted, to live as each of us do even within the confounds of having previously held the universe in his hand. If Jesus really was a person and lived as such rather than simply becoming human, how might this help us answer questions about those with a disability or LGBT people?
What is required to be a person rather than just being human? And is this important? Can you see the difference?
The doctrine of divine simplicity is complicated and controversial—even among those who admire Aquinas’ philosophical theology. But the following account should provide the reader with a rough sketch of what this doctrine involves. Consider the example human being. A person is a human being in virtue of her humanity, where “humanity” denotes a species-defining characteristic. That is, humanity is an essence or “formal constituent” that makes its possessor a human being and not something else (ST Ia 3.3). Of course, a human being is also material being. In virtue of materiality, she possesses numerous individuating accidents. These would include various physical modifications such as her height or weight, her particular skin pigmentation, her set of bones, and so forth. According to Aquinas, none of these accidental traits are included in her humanity (indeed, she could lose these traits, acquire others, and remain a human being). They do, however, constitute the particular human being she is. In other words, her individuating accidents do not make her human, but they do make her a particular exemplification of humanity. This is why it would be incorrect to say that this person is identical to her humanity; instead, the individuating accidents she has make her one of many instances thereof.
