In 692, an illegitimate council was called at Constantinople in order to issue disciplinary decrees for II and III Constantinople. This council was known as the Quinisext Council. Some of the canons decreed there were in direct contradiction to the practices of the West. For example, it was decreed that Christ was forbidden to be represented in the form of a lamb. In response to this, Pope Sergius refused to recognize the council and ordered the singing of the Agnus Dei in the Mass!
