Whether This Is True: "God Is Man"?
Arg. 1 Objection 1
Ad primum sic proceditur. Videtur quod haec sit falsa, Deus est homo. Omnis enim propositio affirmativa in materia aliqua remota est falsa. Sed haec propositio, Deus est homo, est in materia remota, quia formae significatae per subiectum et praedicatum sunt maxime distantes. Cum ergo praedicta propositio sit affirmativa, videtur quod sit falsa.
It would seem that this is false: "God is man." For every affirmative proposition of remote matter is false. Now this proposition, "God is man," is on remote matter, since the forms signified by the subject and predicate are most widely apart. Therefore, since the aforesaid proposition is affirmative, it would seem to be false.
Arg. 2 Objection 2
Praeterea, magis conveniunt tres personae ad invicem quam humana natura et divina. Sed in mysterio Trinitatis una persona non praedicatur de alia, non enim dicimus quod pater est filius, vel e converso. Ergo videtur quod nec humana natura possit praedicari de Deo, ut dicatur quod Deus est homo.
Further, the three Divine Persons are in greater mutual agreement than the human nature and the Divine. But in the mystery of the Incarnation one Person is not predicated of another; for we do not say that the Father is the Son, or conversely. Therefore it seems that the human nature ought not to be predicated of God by saying that God is man.
Arg. 3 Objection 3
Praeterea, Athanasius dicit quod, sicut anima et caro unus est homo, ita Deus et homo unus est Christus. Sed haec est falsa, anima est corpus. Ergo et haec est falsa, Deus est homo.
Further, Athanasius says (Symb. Fid.) that, "as the soul and the flesh are one man, so are God and man one Christ." But this is false: "The soul is the body." Therefore this also is false: "God is man."
Arg. 4 Objection 4
Praeterea, sicut in prima parte habitum est, quod praedicatur de Deo non relative sed absolute, convenit toti Trinitati et singulis personis. Sed hoc nomen homo non est relativum, sed absolutum. Si ergo vere praedicatur de Deo, sequitur quod tota Trinitas et quaelibet persona sit homo. Quod patet esse falsum.
Further, it was said in the First Part (Q. 39, A. 4) that what is predicated of God not relatively but absolutely, belongs to the whole Trinity and to each of the Persons. But this word "man" is not relative, but absolute. Hence, if it is predicated of God, it would follow that the whole Trinity and each of the Persons is man; and this is clearly false.
Sed contra On the contrary
Sed contra est quod dicitur Philipp. II, qui, cum in forma Dei esset, exinanivit semetipsum, formam servi accipiens, in similitudinem hominum factus et habitu inventus ut homo. Et sic ille qui est in forma Dei, est homo. Sed ille qui est in forma Dei, est Deus. Ergo Deus est homo.
On the contrary, It is written (Phil. 2:6, 7): "Who being in the form of God . . . emptied Himself, taking the form of a servant, being made in the likeness of man, and in habit found as a man"; and thus He Who is in the form of God is man. Now He Who is in the form of God is God. Therefore God is man.
Respondeo I answer that
Respondeo dicendum quod ista propositio, Deus est homo, ab omnibus Christianis conceditur, non tamen ab omnibus secundum eandem rationem. Quidam enim hanc propositionem concedunt non secundum propriam acceptionem horum terminorum. Nam Manichaei verbum Dei dicunt esse hominem, non quidem verum, sed similitudinarium, inquantum dicunt filium Dei corpus phantasticum assumpsisse, ut sic dicatur Deus esse homo sicut cuprum figuratum dicitur homo, quia habet similitudinem hominis. Similiter etiam illi qui posuerunt quod in Christo anima et corpus non fuerunt unita, non posuerunt quod Deus sit verus homo, sed quod dicatur homo figurative, ratione partium. Sed utraque harum opinionum supra improbata est. Alii vero e converso ponunt veritatem ex parte hominis, sed negant veritatem ex parte Dei. Dicunt enim Christum, qui est Deus homo, esse Deum, non naturaliter, sed participative, scilicet per gratiam, sicut et omnes sancti viri dicuntur dii, excellentius tamen Christus prae aliis, propter gratiam abundantiorem. Et secundum hoc, cum dicitur, Deus est homo, ly Deus non supponit verum et naturalem Deum. Et haec est haeresis Photini, quae supra improbata est. Alii vero concedunt hanc propositionem cum veritate utriusque termini, ponentes Christum et verum Deum esse et verum hominem, sed tamen veritatem praedicationis non salvant. Dicunt enim quod homo praedicatur de Deo per quandam coniunctionem, vel dignitatis, vel auctoritatis, vel etiam affectionis aut inhabitationis. Et sic posuit Nestorius Deum esse hominem, ut per hoc nihil aliud significetur quam quod Deus est homini coniunctus tali coniunctione quod homo inhabitetur a Deo, et uniatur ei secundum affectum, et secundum participationem auctoritatis et honoris divini. Et in similem errorem incidunt qui ponunt duas hypostases vel duo supposita in Christo. Quia non est possibile intelligi quod duorum quae sunt secundum suppositum vel hypostasim distincta, unum proprie praedicetur de alio, sed solum secundum quandam figurativam locutionem, inquantum in aliquo coniunguntur; puta si dicamus Petrum esse Ioannem, quia habent aliquam coniunctionem ad invicem. Et hae etiam opiniones supra reprobatae sunt. Unde, supponendo, secundum veritatem Catholicae fidei, quod vera natura divina unita est cum vera natura humana, non solum in persona, sed etiam in supposito vel hypostasi, dicimus esse veram hanc propositionem et propriam, Deus est homo, non solum propter veritatem terminorum, quia scilicet Christus est verus Deus et verus homo; sed etiam propter veritatem praedicationis. Nomen enim significans naturam communem in concreto potest supponere pro quolibet contentorum in natura communi, sicut hoc nomen homo potest supponere pro quolibet homine singulari. Et ita hoc nomen Deus, ex ipso modo suae significationis, potest supponere pro persona filii Dei, ut in prima parte habitum est. De quolibet autem supposito alicuius naturae potest vere et proprie praedicari nomen significans illam naturam in concreto, sicut de Socrate et Platone proprie et vere praedicatur homo. Quia ergo persona filii Dei, pro qua supponit hoc nomen Deus, est suppositum naturae humanae, vere et proprie hoc nomen homo potest praedicari de hoc nomine Deus, secundum quod supponit pro persona filii Dei.
I answer that, This proposition "God is man," is admitted by all Christians, yet not in the same way by all. For some admit the proposition, but not in the proper acceptation of the terms. Thus the Manicheans say the Word of God is man, not indeed true, but fictitious man, inasmuch as they say that the Son of God assumed an imaginary body, and thus God is called man as a bronze figure is called man if it has the figure of a man. So, too, those who held that Christ's body and soul were not united, could not say that God is true man, but that He is figuratively called man by reason of the parts. Now both these opinions were disproved above (Q. 2, A. 5; Q. 5, A. 1).
Some, on the contrary, hold the reality on the part of man, but deny the reality on the part of God. For they say that Christ, Who is God and man, is God not naturally, but by participation, i.e. by grace; even as all other holy men are called gods—Christ being more excellently so than the rest, on account of His more abundant grace. And thus, when it is said that "God is man," God does not stand for the true and natural God. And this is the heresy of Photinus, which was disproved above (Q. 2, AA. 10, 11). But some admit this proposition, together with the reality of both terms, holding that Christ is true God and true man; yet they do not preserve the truth of the predication. For they say that man is predicated of God by reason of a certain conjunction either of dignity, or of authority, or of affection or indwelling. It was thus that Nestorius held God to be man—nothing further being meant than that God is joined to man by such a conjunction that man is dwelt in by God, and united to Him in affection, and in a share of the Divine authority and honor. And into the same error fall those who suppose two supposita or hypostases in Christ, since it is impossible to understand how, of two things distinct in suppositum or hypostasis, one can be properly predicated of the other: unless merely by a figurative expression, inasmuch as they are united in something, as if we were to say that Peter is John because they are somehow mutually joined together. And these opinions also were disproved above (Q. 2, AA. 3, 6).
Hence, supposing the truth of the Catholic belief, that the true Divine Nature is united with true human nature not only in person, but also in suppositum or hypostasis; we say that this proposition is true and proper, "God is man"—not only by the truth of its terms, i.e. because Christ is true God and true man, but by the truth of the predication. For a word signifying the common nature in the concrete may stand for all contained in the common nature, as this word "man" may stand for any individual man. And thus this word "God," from its very mode of signification, may stand for the Person of the Son of God, as was said in the First Part (Q. 39, A. 4). Now of every suppositum of any nature we may truly and properly predicate a word signifying that nature in the concrete, as "man" may properly and truly be predicated of Socrates and Plato. Hence, since the Person of the Son of God for Whom this word "God" stands, is a suppositum of human nature this word man may be truly and properly predicated of this word "God," as it stands for the Person of the Son of God.
Ad 1 Reply to Objection 1
Ad primum ergo dicendum quod, quando formae diversae non possunt convenire in unum suppositum, tunc oportet quod propositio sit in materia remota cuius subiectum significat unam illarum formarum, et praedicatum aliam. Sed quando duae formae possunt convenire in unum suppositum, non est materia remota, sed naturalis vel contingens, sicut cum dico, album est musicum. Natura autem divina et humana, quamvis sint maxime distantes, tamen conveniunt per incarnationis mysterium in uno supposito, cui neutra illarum inest per accidens, sed secundum se. Et ideo haec propositio, Deus est homo, non est neque in materia remota neque in materia contingenti, sed in materia naturali. Et praedicatur homo de Deo, non per accidens, sed per se, sicut de sua hypostasi, non quidem ratione formae significatae per hoc nomen Deus; sed ratione suppositi, quod est hypostasis humanae naturae.
When different forms cannot come together in one suppositum, the proposition is necessarily in remote matter, the subject signifying one form and the predicate another. But when two forms can come together in one suppositum, the matter is not remote, but natural or contingent, as when I say: "Something white is musical." Now the Divine and human natures, although most widely apart, nevertheless come together by the mystery of the Incarnation in one suppositum, in which neither exists accidentally, but [both] essentially. Hence this proposition is neither in remote nor in contingent, but in natural matter; and man is not predicated of God accidentally, but essentially, as being predicated of its hypostasis—not, indeed, by reason of the form signified by this word "God," but by reason of the suppositum, which is a hypostasis of human nature.
Ad 2 Reply to Objection 2
Ad secundum dicendum quod tres personae divinae conveniunt in natura, distinguuntur tamen in supposito, et ideo non praedicantur de invicem. In mysterio autem incarnationis naturae quidem, quia distinctae sunt, de invicem non praedicantur secundum quod significantur in abstracto, non enim natura divina est humana, sed quia conveniunt in supposito, praedicantur de invicem in concreto.
The three Divine Persons agree in one Nature, and are distinguished in suppositum; and hence they are not predicated one of another. But in the mystery of the Incarnation the natures, being distinct, are not predicated one of the other, in the abstract. For the Divine Nature is not the human nature. But because they agree in suppositum, they are predicated of each other in the concrete.
Ad 3 Reply to Objection 3
Ad tertium dicendum quod anima et caro significantur ut in abstracto, sicut divinitas et humanitas. In concreto vero dicuntur animatum et carneum, sive corporeum, sicut ex alia parte Deus et homo. Unde utrobique abstractum non praedicatur de abstracto, sed solum concretum de concreto.
"Soul" and "flesh" are taken in the abstract, even as Godhead and manhood; but in the concrete we say "animate" and "carnal" or "corporeal," as, on the other hand, "God" and "man." Hence in both cases the abstract is not predicated of the abstract, but only the concrete of the concrete.
Ad 4 Reply to Objection 4
Ad quartum dicendum quod hoc nomen homo praedicatur de Deo ratione unionis in persona, quae quidem unio relationem importat. Et ideo non sequitur regulam eorum nominum quae absolute praedicantur de Deo ab aeterno.
This word "man" is predicated of God, because of the union in person, and this union implies a relation. Hence it does not follow the rule of those words which are absolutely predicated of God from eternity.
