Eastern Orthodox teaching regarding the Filioque

William La Due describes modern Orthodox theological scholarship as split between a group of scholars that hold to a ""strict traditionalism going back to Photius"" and other scholars that are ""not so adamantly opposed (to the filioque)"". Vladimir Lossky asserted that any notion of a double procession of the Holy Spirit from both the Father and the Son was incompatible with Orthodox theology. Orthodox scholars who share Lossky's view include Dumitru Stăniloae, John Romanides and Michael Pomazansky. Sergius Bulgakov, however, was of the opinion that the filioque did not represent an insurmountable obstacle to reunion of the Eastern Orthodox and Roman Catholic churches.The Eastern Orthodox interpretation of the Trinity is that the Holy Spirit originates, has his cause for existence or being (manner of existence) from the Father alone as ""One God, One Father"". That the filioque confuses the theology as it was defined at the councils at both Nicene and Constantinople. The position that having the creed say ""the Holy Spirit which proceeds from the Father and the Son"", does not mean that the Holy Spirit now has two origins, is not the position the West took at the Council of Florence. Where the Roman Catholic side explicitly stated that the Holy Spirit has its cause of existence from the Father and the Son.
