In the book, Comparative Theology by H.H. Pope Shenouda, it mentions that Catholics and Protestants believe that the Holy Spirit proceeded from the Father and the Son, but our Coptic Church says that the Holy Spirit proceeded from the Father only. I don't understand what the difference is.
We believe that the Father, Son, and Holy Spirit are a Trinity so, in my mind, if the Holy Spirit proceeded from the Father, He must've also proceeded from the Son. However, Pope Shenouda really emphasized that this is a major difference.
Could someone please explain this to me?
