Making a Case for an Essential Dependence Model in the
Doctrine of the Eternal Generation of the Son.
Contra Causal dependence, Counterfactual dependence, and
Modal dependence models.
Why Eternal Generation Matters:
1. Ensures equality, unity and distinctness.
- Equality: Like Father, like Son.
- Unity: Bound together by eternal relations of origin.
- Distinctness: Unbegotten Father, begotten Son.
2. Affirmed by the Church for 1700 years e.g. Justin Martyr,
Athanasius, Gregory of Nazianzus, Augustine, Aquinas, Luther, Calvin, John Owen
etc.
3. Underlies the Gospel.
“Behind the missions of the Son and the Spirit stand their
eternal processions, and when they enter the history of salvation, they are
here as the ones who, by virtue of who they eternally are, have these specific
relations to the Father. For this reason, the Trinity is not just what God is
at home in himself, but the same Trinity is also what God is among us for our
salvation.” Fred Sanders.
Poor models of Eternal Generation
Philosophically, how should we understand the doctrine of
eternal generation? In what sense does the Son depend on the Father for his
existence?
Causal Dependence Model
The Son causally depends on the Father.
X causally depends on Y ⇔ Y causes X
Necessarily, the Father causes the Son to exist.
Problems:
Causation is diachronic. The cause always precedes the
effect in time. This implies Arianism – there was a time when the Son was not.
Causation relates events (including events involving
persons), but not persons.
Modal Dependence Modal
The Son modally depends on the Father.
X modally depends on Y ⇔ Necessarily, X exists only if Y exists
Problems:
Not asymmetric: The Father also modally depends on the Son.
We do not want this as the Father is unbegotten, and only the Son is begotten.
If modal dependence is true, we will have eternal generation going both ways,
that is, the Father eternally begets the Son, and vice versa.
Unwanted dependence occurs: For example, if modal dependence
is true, the Son modally depends on Universals like the Number 2 as Universals
exist eternally.
The Trinity has 3 persons. Hence, the modal dependence model
would require modal dependence upon the numbers 1, 2 and 3, with the Son being
the second person of the Trinity. This would also imply that the Son is eternally
begotten from the Number 2.
Counterfactual Dependence Model
Not applicable in our discussion since God is a necessary
being existing in every possible world. Both the Father and the Son necessarily exist in every possible world, and counterfactuals of non-existence of a
necessary being do not exist.
We need a model of Eternal Generation with the following
features:
- · Not diachronic
- · Can relate persons
- · Asymmetric
- · Precludes unwanted dependence
Essential Dependence Model
Definitions:
1) The Essence of something, X, is what X is, or what it is
to be X.
2) Essential Definition: An essential definition specifies
the essence of a thing, what it is to be that very thing.
Example of an essential definition:
To be a human being is to be a rational (differentia)
animal (genus).
3) Essential Dependence
X essentially depends on Y ⇔ Y is part of the essential definition
of X
Example: The singleton set {Socrates} essentially depends on
Socrates. To be {Socrates} is to be the set that contains only Socrates as a
member.
Essential Dependence Model of Eternal Generation:
Eternal generation is a form of essential dependence.
To say that the Son is eternally begotten of the Father is
to say that the Son essentially depends on the Father. The Father is part of the
essential definition of the Son, but not vice versa. Or more formally:
Essential Dependence Model:
The Son is eternally begotten of the Father ⇔ The
Father is a constituent of a real definition of the Son, and the Son exists
eternally.
According to the essential dependence model, the essence of the
Son involves the Father. The Father is part of what the Son is, or what it is
to be the Son.
Essential definition of the Son
To be the Son is to be the divine person who is the
image of the Father. (Heb 1:3, 2 Cor 4:4, Col 1:15, Phil 2:6).
Essential definition of the Father
To be the Father is to be the divine person who is the
ultimate source of all things (or, on whom all things ultimately
depend). (Heb 2:10, Ro 11:36, 1 Cor 8:6).
Benefits of Essential Dependence.
Not diachronic: The Son and the Father exist simultaneously.
Can relate persons: Essential dependence can relate anything
(not just events like Causal dependence).
Asymmetric: The Son essentially depends upon the Father, but
not vice versa.
Precludes unwanted dependence: The Son does not essentially
depend on abstract universals like the Number 2, for instance (as in Modal
dependence).
Avoids Subordinationism within the Godhead:
1) Necessary existence: Essential dependence is compatible
with necessary existence. There never was a time when the Son was not (contra
Arius). The Son exists necessarily, and yet is essentially dependent upon the
Father.
2) Self-Existence (Aseity): Essential dependence is not a
form of causation. In no way does it imply that the Father causes the Son’s
existence. Thus, the Son possesses aseity.
Causation also implies succession in time; if the Father
causes the Son’s existence, then the Father is chronologically prior to
the Son (Arianism).
Possible objections:
Aseity = existing without being caused by anything else; Or
Aseity = existing without depending on anything else.
Reply: The Son is self-existing with respect to the divine
essence, but not with respect to his person. Hence, we make a distinction
between ousia and hupostasis (Calvin).
“Therefore we say that deity in an absolute sense exists of
itself; whence likewise we confess that the Son since he is God, exists of
himself, but not in respect of his Person; indeed, since he is the Son, we say
that he exists from the Father. Thus his essence is without beginning; while
the beginning of his person is God himself.” (John Calvin, Institutes of the Christian Religion & 2,
ed. John T. McNeill, trans. Ford Lewis Battles, vol. 1, The Library of
Christian Classics (Louisville, KY: Westminster John Knox Press, 2011), 154.)
