Lecture 51

51. Christ as Creature and the Problem of Precise Language

Summary
This lecture addresses Articles 8-10 from Aquinas’s treatment of the Incarnation, focusing on whether Christ can be called a creature, whether the man Christ began to be, and the unity of Christ despite possessing two natures. Berquist emphasizes the crucial distinction between absolute and qualified (secundum quid) predication, warning of heretical misinterpretation when theological language is imprecise. The lecture explores the medieval logical framework of supposition theory to clarify how properties of human and divine natures are predicated of Christ as one suppositum.

Lecture Notes

Main Topics #

Article 8: Can Christ Be Called a Creature? #

  • The fundamental problem: Christ’s human nature is created, but calling Christ simply “a creature” risks suggesting the divine person is created (Arian heresy)
  • The critical distinction between absolute predication (simpliciter) and qualified predication (cum determinatione/secundum quid)
  • Properties of human nature may be attributed to Christ, but with care to avoid confusing them with properties of the divine person
  • Jerome’s principle: “From words disorderly put forward, heresy arises” - language must be carefully guarded
  • Solution: Say “Christ, according to his human nature, is a creature” rather than “Christ is a creature” (without qualification)

Article 9: Did the Man Christ Begin to Be? #

  • The apparent contradiction: Christ (the person) is eternal, yet the man Christ assumed human nature in time
  • The distinction between suppositum (the divine person) and nature (human nature)
  • Logical principle: “Beginning to be a man” does not entail “beginning to be” simply
  • When “man” stands in the subject position, it designates the suppositum (eternal); when in the predicate, it signifies the nature (temporal)
  • False statement: “This man began to be” (refers to the eternal person)
  • True statement: “Christ began to be a man” (refers to the assumption of human nature)

Article 10: Is Christ One or Two? #

  • The unity of Christ: one suppositum (person) subsisting in two natures
  • Distinction between concrete and abstract predication:
    • Concrete: signifies the thing having the nature (e.g., “God,” “man”)
    • Abstract: signifies the nature itself (e.g., “deity,” “humanity”)
  • The divine nature can be predicated of Christ both ways; human nature only concretely
  • Illustration: The two lines meeting at a point - the eternal divine person is the endpoint at which the temporal human nature is “drawn”

Key Arguments #

On Creature Language #

Objection: Christ’s human nature is created; therefore Christ is a creature

Response:

  • Distinguish between speaking absolutely and with determination
  • Dangerous to say “Christ is a creature” without qualification (heretical confusion)
  • Safe to say “Christ, according to his human nature, is a creature”
  • Things about which no confusion regarding the divine person can arise (e.g., “Christ suffered, died, was buried”) may be said simply
  • Example of the Ethiopian: We don’t say “the Ethiopian is white” simply, but “the Ethiopian is white in his teeth” (Aristotle’s example)

On Beginning to Be #

Objection: Augustine says “Before the world was, neither we were, nor that mediator of God and men, the man Christ, Jesus”; therefore the man Christ began to be

Response:

  • The statement is false if understood simply, because the suppositum is eternal
  • Logical principle: Beginning to be a man does not entail beginning to be simply
  • Analogy: “Socrates became white” does not mean “Socrates became colored” (the superior does not follow from the inferior)
  • Supposition: In “the man began to be,” the term “man” in subject position stands materially for the suppositum (eternal person), so the statement is false
  • But “Christ began to be a man” is true, because “man” in the predicate formally signifies the nature

On Unity Despite Two Natures #

Objection: Christ is God and man; therefore Christ is two

Response:

  • Every thing that is, insofar as it is, is one (Boethius principle)
  • One suppositum subsists in two natures
  • The human nature is individual and substantial, but not a person, because it does not subsist by itself
  • Analogy: A hand is individual and substantial, but not a person because it does not subsist apart
  • Similarly, human nature in Christ is individual but not a person because it does not subsist apart from the divine person

Important Definitions #

Supposition (suppositio) #

The manner in which a term stands for or refers to a thing:

  • Material supposition: A term stands for the suppositum (the individual thing or person)
  • Formal supposition: A term stands for the nature or essence signified
  • In “Christ, according as he is man, is a creature”: the predicate (creature) holds formally for the nature; the subject-term holds materially for the suppositum

Reduplication (cum determinatione) #

A qualifying phrase that specifies under which aspect something is predicated:

  • “Christ, according as he is man” or “Christ, as man”
  • When a reduplicative phrase is used, the predicate holds more properly for the nature than for the suppositum
  • Example: “Christ, according as man, is a creature” (true - refers to nature) vs. “Christ, according as this man, is a creature” (false - refers to eternal person)

Suppositum and Hypostasis (ὑπόστασις) #

The individual substance that subsists in itself

  • In Christ: one suppositum/hypostasis that subsists in both divine and human natures
  • Distinguished from nature: the suppositum is “what” has the nature
  • Human nature in Christ is not a suppositum because it does not subsist by itself

Concrete vs. Abstract Predication #

  • Concrete: signifies the thing having the nature (“God,” “man,” “white thing”)
  • Abstract: signifies the nature itself (“deity,” “humanity,” “whiteness”)
  • In creatures, only concrete can be truly predicated (I am a man, not humanity)
  • In God, due to divine simplicity, God is his goodness/deity/etc.

Examples & Illustrations #

The Two Lines Analogy #

  • One line (divine nature) exists eternally with its endpoint (divine person)
  • Another line (human nature) is drawn to that same endpoint in time
  • The endpoint does not begin to be when the second line is drawn; the second line begins to be
  • Illustrates how the person is eternal while the human nature begins to be in time

The Ethiopian Example (Aristotle) #

  • We do not say “the Ethiopian is white” simply, but “the Ethiopian is white in his teeth”
  • When a property belongs only to a part, predication must be qualified
  • Similarly, when Christ has a property through human nature alone, it must be qualified
  • We say simply “Christ suffered, died, was buried” because these cannot be confused with divine properties

The Hand of a Man #

  • A hand is substantial and individual, but not a person because it does not subsist by itself
  • Similarly, human nature in Christ is individual and substantial, but not a person because it does not subsist apart from the divine person

Notable Quotes #

“From words disorderly put forward, heresy arises.” - Jerome (cited by Thomas, on the danger of imprecise theological language)

“Never should it be said that Christ is a creature.” - Ambrose (on the necessity of qualified predication)

“Everything that is, insofar as it is, is one.” - Boethius (principle of unity)

“Before the world was, neither we were, nor that mediator of God and men, the man Christ, Jesus.” - Augustine (on the temporal dimension of Christ’s human nature)

Questions Addressed #

Q: Can Christ be called a creature? #

A: Yes, but only with determination. “Christ, according to his human nature, is a creature” is safe; “Christ is a creature” (simply) is dangerous and could suggest the divine person is created. The Arians made precisely this heretical move, attributing creaturely status to the divine person.

Q: Did the man Christ begin to be? #

A: No, if understood simply. The suppositum (eternal divine person) did not begin to be. However, “Christ began to be a man” is true because human nature began to be assumed in the eternal suppositum. The logical principle: beginning to be a man does not entail beginning to be simply.

Q: How is Christ one if he has two natures? #

A: One suppositum subsists in two natures. The human nature in Christ is individual and substantial, but not a person, because it does not subsist by itself apart from the divine person (unlike ordinary human persons). The divine nature can be predicated of Christ both concretely and abstractly; human nature only concretely, ensuring his unity.

Q: Why the distinction between subject and predicate position? #

A: When a term is in the subject position, it stands materially for the suppositum; in the predicate, it stands formally for the nature. This explains why “this man is eternal” (false - subject refers to person) but “Christ, according as man, is temporal” (true - predicate refers to nature) both involve the term “man” but with different truth values.

Pedagogical Observations #

  • Berquist emphasizes the Latin and Greek logical framework as essential for understanding Christological doctrine
  • Medieval supposition theory is not merely grammatical but theologically indispensable
  • Heretical errors arise from inattention to precise logical distinctions
  • The discovery of good definitions and distinctions is a major accomplishment of reason
  • Understanding requires sustained reflection and multiple readings
  • Custom and precedent shape language use, even when not strictly accurate (example: calling blessing “grace”)
