So not trying to cause another big firestorm. Am wondering how Augustine’s view of God as simple substance and thus deriving the filioque changed to RC and EO agreeing that father generates both son and holy spirit.
Seems like definition of what filioque means has changed over time?
“The Holy Spirit is neither generate nor ingenerate, but rather is He who proceeds from the Father and the Son, as a harmony, we may say of Both.”
St. Eucherius of Lyons, Spic. Rom., 5:93, written after 454 A.D.
On the Trinity, Book 6:6-7, by St. Augustine, he teaches that God is simple substance becaues He is unchangable, but still has attributes, which are one:
“The Son is in no respect equal with the Father, if He is found to be unequal in anything which has to do with signifying His substance, as we have already shown. But the apostle has said that He is equal. Therefore the Son is equal with the Father in all things, and is of one and the same substance”
[The Holy Spirit] “consists in the same unity of substance, and in the same equality”
“And in Him it is not one thing to be blessed, and another to be great, or wise, or true, or good, or in a word to be Himself”
