During the [[Middle Ages]] the Church underwent a time of missionary activity and expansion. After numerous disputes between eastern and western churches that became more pronounced from the ninth century onwards, the Church underwent the [[Great Schism]] in 1054 that divided it into a Western (Latin) branch, which has been called the Catholic Church and an Eastern branch, which has become known as the [[Orthodox Church]]. Both traced their roots to the time of Jesus, but the Orthodox Church did not acknowledge the Pope as the one leader of the Church and instead believed that all of the patriarchs were equals. | During the [[Middle Ages]] the Church underwent a time of missionary activity and expansion.
