Why was it OK for the Latin Church to add the filioque to the Nicene Creed? The original creed did not contain it. The Holy Spirit proceeds only from the Father in the original creed. The Nicene Creed is so very important to us and we recite it at every mass, yet it is not the original. The whole theology that the Holy Spirit is the result of the love of the Father and Son for each other, and how that is reflected in the sacrament of marriage, could not have been developed if the filioque hadn’t been added. Also, I believe it is a huge stumbling block to the reunification of the East and the West Churches which Pope John Paul II was so eager to achieve.
