Council of Toledo of 447
The Council of Toledo of 447 was the second Council of Toledo. It was a national council held against the Priscillianists, as called for by Pope Leo I. Nineteen bishops participated in the council, which condemned the heresy and the followers of Priscillian and affirmed the earlier First Council of Toledo, from which its Creed is based off. It gave a profession of faith against all heretics with 18 anathemas attached against the doctrines of Priscillian. The council is notable for its successful subduing of Priscillianism, expressing a definition of dyophysitism before the Council of Chalcedon, its affirmation of the First Council of Toledo, and being the first known western council to include the "filioque" in its creed, following in the doctrine from Pope Leo I.
