"We accept the same Nicene Creed." Huh? You mean in the Greek?

The Greek Orthodox creed is quite different at least in their English translation at https://www.goarch.org/-/the-nicene-creed (official website)

"And in the Holy Spirit, the Lord, the Creator of life, Who proceeds from the Father." Not the Father and Son. The Holy Spirit is also "Creator," not "giver"

"came down from heaven and was incarnate of the Holy Spirit and the Virgin Mary and became man." Quite different from the Catholic, "by the Holy Spirit was incarnate of the Virgin Mary, and became man.” Evidently, the Orthodox like to give credit to Mary, the Mother of God, for this event, not just the Holy Spirit. 

For sure the Orthodox will not be persuaded to say the awkward Latin-ish word “consubstantial.” (And why would anyone say it?) Instead, they say, “of one essence with the Father."

It's interesting to see the marked differences even between the Catholic English and the Catholic French. Not a monolithic Church.
