I am making a statement of fact. The creed recited by most Catholics is not the creed approved by the Fathers of the Holy Councils of Nicea & Constantinople. Words matter. “Filioque” radically alters the Trinitarian theology of the Creed. by creating a double procession of the Holy Spirit. From the Orthodox perspective, it is heretical.
I understand where you are coming from, but I don’t believe the Nicene Creed is heretical.
