In Timothy (Kallistos) Ware’s book on the Orthodox, he had the following to say about the Filioque. That is what I was referring to about St Augustine.
"When Augustine stated that the Spirit proceeds from both Father and Son, he was careful to qualify this by insisting that the Spirit does not proceed from the Son in the same manner as He proceeds from the Father. There are two different kinds of procession. The Spirit proceeds from the Father principaliter, ‘principally’ or ‘principially’, states Augustine, but He proceeds from the Son only per donum Patris, ‘through the gift of the Father’. The procession of the Spirit from the Son, that is to say, is specifically something that the Father Himself has conferred upon the Son. Just as the Son receives all things as a gift from the Father, so also it is from the Father that He receives the power to ‘spirate’ or ‘breathe forth’ the Spirit. In this way for Augustine, as for the Cappadocians, the Father remains the ‘fountainhead of the deity’, the sole source and ultimate origin within the Trinity. Augustine’s teaching that the Spirit proceeds from the Father and from the Son – but with the qualification that He proceeds from the Son, not ‘principially’ but ‘through the gift of the Father’ – is thus not so very different from Gregory of Nyssa’s view that the Spirit proceeds from the Father through the Son. The Council of Florence, in endorsing Augustine’s doctrine of Double Procession, explicitly re-emphasized the point that the spiration of the Spirit is conferred on the Son by God the Father. The contrast, then, between Orthodoxy and Rome as regards the ‘monarchy’ of the Father is not nearly so stark as appears at first sight.
there is today a school of Orthodox theologians who believe that the divergence between east and west over the Filioque, while by no means unimportant, is not as fundamental as Lossky and his disciples maintain. The Roman Catholic understanding of the person and work of the Holy Spirit, so this second group of Orthodox theologians conclude, is not basically different from that of the Christian east; and so we may hope that in the present-day dialogue between Orthodox and Roman Catholics an understanding will eventually be reached on this thorny question."
I don’t agree that the Filioque needed to be added in the manner that it was added. I think Rome road roughshod over the rest of the church and did not put the full explanation of their emphasis on consubstantiation out there. Had they done this, a lot of the problems with the Eastern Church could have been avoided. And also perhaps if the Latins had not sacked Constantinople in the Fourth Crusade… but that is another topic.
