St. Gregory Palamas 1296-1359
How can you say that which is not boldly spoken by the proclaiming truth, which the Spirit did not announce, the proclaimer of all truth, to which He did not bear witness and which He did not relay, He who notified all His friends about all that He heard from the Father, Who came so that He might bear witness to the truth? How can you introduce an alien addition to the specific creed, which was written jointly by the chosen Fathers who, gathered together spiritually for this, wrote the Creed from a sincere opinion of the Father and the Son and the Holy Spirit and gave it as a touchstone of the true knowledge of God and immutable confession of faith for all the elect to direct the word of truth? …In our opinion, at first your addition needs to be taken away, and then to consider whether the Holy Spirit is from the Son or not, and to maintain whether or not it corresponds to the extant decision of the God-bearers. (Apodictic Treatise 1)
