By this point, [[Arianism]] had become largely marginalized and many Arians were accepted back into the Church. But a new attack on the Person of [[Christ]] emerged in the form of the Monothelites. The Monothelites argued that Christ has only one will, for He is one person albeit with two natures. The Council felt that this "impaired the fullness of Christ's humanity," and that human nature without human will would be incomplete. That affirmed that since Christ was true man and true God, He must have two wills: a human will and a divine will. [[Monothelitism]] was condemned as heresy.

Islam's speed was striking, starting with only Hejaz at the Prophet's death (632) and ending with Syriaas well as Cyrus of Alexandria, Palestine Paul and Egypt within the 50 years. Islam was at the walls Peter of Constantinople after this time, and almost captured the city. Within a hundred years, Islam had taken North AfricaTheodore of Pharan, went through Spain and "forced western Europe to fight Pope Agatho for its life at the Battle of Poitiers." The old Empires were their part in no position to resist propagating the conquests heresy of IslamMonothelitism. Byzantium lost her eastern possessions and the [[Patriarchate]]s of Jerusalem, Antioch and Alexandria. Constantinople was now without rival, but was never free from Muslim attacks. It held out only eight centuries more, and then succumbed to invasion. Christendom did survive, but only with difficulty.''
