The Lateran Council, 649

apostolic words about the same Savior not to one and the same person and essentially to the same Lord Himself and God, our Jesus Christ, according to blessed Cyril, so that he is shown to be by nature God and likewise man, let him be condemned.

270. Can. 17. If anyone in word and mind does not properly and truly confess according to the holy Fathers all even to the last portion that has been handed down and preached in the holy, Catholic, and apostolic Church of God, and likewise by the holy Fathers and the five venerable universal Councils, let him be condemned.

271. Can. 18.
