Consubstantial/homoousian/ομοοĻĻιον means same substance/essence/nature.
I am glad we agree on this (assuming the āιονā is at the end of the correct Greek. I donāt read Greek, but by now I recognize the end of the word Homoousian). BTW, there are āEnglishizedā versions of homoousian too like āhomoousiosā that also are the same word.
Consubstantial has the same meaning whether you apply it to humanity (generic to use your term) or to the Trinity (numeric to use your term). God has one nature and humanity has one nature.
āThat they (the disciples) may be one (generically in substance, a single nature) as thou, Father, art in me I in thee, that they also may be one (numerically in substance, a single nature)ā
I do not understand.
I claimed that āhomoousianā has two meanings.
When applied humanity, it means āone generically in substance, a single natureā when applied to God it means āone numerically in substance, a single nature.ā
You say, āhomoousianā has one meaning, but then say:
āThat they (the disciples) may be one (generically in substance, a single nature) as thou, Father, art in me I in thee, that they also may be one (numerically in substance, a single nature)ā
You are giving it two meaning and claiming it has one???
Now two other points of importance that may be worthwhile as you try to explain to me what you mean (and I hope you will address also).
#1 These different āmeaningsā of homoousian are just āas I say.ā There is evidence for them in the ancient Greek. Scholars talk about them. If you intend to say there are not two meanings, that is all good and well. But, I have already seen a Catholic poster claim that, āNo we are not consubstantial.ā And that we are not consubstantial with Christ. This shows a misunderstanding AND denies Catholic dogma. It will take a lot more than your confident assurance for me to believe that the idea that Homoousian has more than one meaning was just a big misunderstanding.
Here is the discussion of Catholic Father (and Scholar) Don Davis:
However, homoousios was at the time a notoriously slippery word and could have three principal meanings. First, it could be generic; of one substance could be said of two individual men, both of whom share human nature while remaining individual men, both of who share human nature while remaining individuals. Secondly, it could signify numerical identity, that is, that the Father and the Sonare identical in concrete being. Finall, it could refer to material things, as two pots are of the same substance because both are made of the same clay.(p. 61 The First Seven Ecumenical Councils (325-787) by Leo D. Davis SJ)
Father Davis continues to explain (like other scholars) that Constintine denied the third meaning was what the council meant. He said the council likely meant the first meaning. AND that Athanasius brought out the second meaning:
But implicit in their statement was numerical identity, that Father and Son are of a single divine substance, an aspect brought out by Athanasius in the course of the long struggle following the Council.(p. 61 The First Seven Ecumenical Councils (325-787) by Leo D. Davis SJ)
Father Davis then tells us that it is likely most bishops opposed the term and āit seems clear that the authority of Constantine was the main motivating force.ā I might mention that Father Davis then offer Ossius of Cordoba as Constantineās advicer who was probably behind Constantineās insistence.
If you search on Google Scholar, you can find MANY discussions of the multiple use of the word.
#2 While Father Davis and many Catholic and Protestant scholars express what I consider to be the historical Catholic view (after all Athanasius is the hero of orthodoxy), there are many MODERN Catholics who have CHANGED their minds on this. Catholic āSocial Trinitariansā if aware of the two meanings, embrace the āgeneric.ā These folks MAY not be Catholic, but they and I agree largely when it comes to the oneness of God. I mention this because I believe I have come across Catholic scholars who say āhomoousian has multiple meanings, but we should use the generic meaning when conceiving of Father, Son, and Holy Spirit.ā That is not a view without adherents within Catholic scholarship, but it is at odds with Athanasius and the culmination of decades of post Nicene wranglings.
