It seems to me that the distinction between ousia and hypostasis emerged after the Council of Nicea, with the Cappadocians. The evidence for this is:
- Athanasius (as quoted) explicitly says so, in the letter Ad Afros- primarily directed as refutation of the Arians.
- The anathema at the end of the (first) Nicene Creed clearly treats them as synonyms (see fourthcentury.com/index.php/nicaea-325-creed-greek)
(?? hmmm… find an Athanasius link & Cappadocians ??)
The distinction I see is that Hypostasis is a partial super-set of ousia; The words agree in one connotation, but disagree in another. Therefore, I am uncertain if they could be strict synonyms.
In the creed you linked to, the relevant creed words (dashes mine) are:
οὐσί-ας, ὁμο-
ούσι-ον, (
ousi-as, [h]omo-
ousi-on )
And, the anathema itself says:
… ἢ ἐξ ἑτέρας
ὑπο-στάσε-
ως ἢ
οὐσί-ας φάσκοντας εἶναι … ([h]ypo-stase-Os,
ousi-as)
- Basil and Gregory both find it necessary to argue for a distinction … which would not be necessary (I suggest) if the difference already existed …
I can understand your thought here, but I don’t think it strong enough.
Perhaps it would be helpful for you to add a statement about what the Arians believed ?
Both, however, argue that ousia is a species/type and hypostasis is an instantiation of that species of type …
Basil even goes so far as saying that we should not use type or genus names in plural. Thus, he says, if there are three men we really should not say “three men” …[as]… the type or specie, remains singular. …
There are some things you say here which I need to review slowly on my own (eg:circa species/type) – hence, be patient if I don’t treat these issues for a week. I also see a few minor deficiencies/pitfalls in the linked translations.
I think Basil still focuses on a problem in Greek grammar which even predates the NT Bible; eg: on the clarity of using collective and non-collective nouns.
A collective noun means that a singular word actually represents also a plurality of actual (or instantiated) things. For example, I can say in English: “The
enemy pursued me”. In this example, “the
enemy” may be either a single man, or many men (even a whole platoon!). That, I think, is what Basil is trying to correct with respect to “God”.
Collective nouns; such as “day”('amera), “rock”(petra), etc. are well known in Greek HOWEVER “God”(the-os) is not a collective noun. True Greeks were pantheistic (eg: pan-the(oi)-istc; all-gods-istic). They would say – The-os, The-oi, The-E, The-ai. A.K.A. God, God(s), Godess … and many people accepted female Gods, SO a collective God statement might easily be mistaken for a “female” one!!!

(Bible doesn’t use em!)
None of “God” words in earlier Greek are collective words, they are simple singulars just as (Petr-os) Peter is, eg: right before a possibly collective (Petra) in Mt. 16:18;
Clearly, in MT, Jesus is working with both a singular and a possibly collective word.
In Greek Jesus’ words correspond literally to: “This **the **rock” or, in more comfortable English “this
very(singular) rock” When Jesus spoke, Peter was already known as a single child of Abraham, eg: a single rock (Petr-os is singular) and Jesus meant him specifically out of
all the brothers in the collective. when he said “this very rock” (BORG alert!)
(Please see Isaiah 51:1 (not 2) for the history of “rock” The naming tradition comes from Abraham being “the” rock, and his children a collective. Note carefully, though, there are no truly female rocks. Sarah is called a
quarry not a rock. )
Basil’s problem is far worse; he really appears to addressing the Greek deficiency about “God”. I don’t know of a standard and more ancient Greek way to distinguish Trinity from female Gods… So I suspect he had to invent a circumlocution (a work “around” way of speaking) about God/Trinity.
Compare and contrast what I am saying with the following:
(To me) Jesus is of the Hypostasis → St. Joseph (at least before age 13), BUT there is no evidence that he is the ousia and “sarks” of St. Joseph. (His literal substance and flesh). This is
still supported in traditional Koine Greek.
My personal opinion is that ousia acts as a synonym for the Latin idea of “substance”; In the Liturgy we say in English “con-
substantial” with the Father where Nicea has “ousia”. (again “with-
substance” does not imply personality in Latin and English sciences).
Now, notice: The Nicean anathema uses the words Hypostasis, and ousia
both; Since ousia of the Father applies to how the Son came from him; Gold, slaves, and adoption, would be false analogies to the Son’s relationship.
I will look for counter-examples, are you aware of any?
I could agree, if you really mean that Nicea invented/discovered a good circumlocution. (??)
