FROM GREGORY THE GREAT TO THE ESTABLISHMENT OF THE PAPACY AS A LEGISLATIVE POWER [590-867 A.D.]

590 Gregory (I) the Great elected pope. He raises the papacy to eminence and determines its future policy. Gregory’s work is of threefold character. (1) He perfects the church ritual and introduces a new mode of chanting, and organises the revenues of the church. (2) He exercises supreme authority over the churches of western Europe. The Lombards are converted from Arianism, 599, and Britain is converted by St. Augustine. (3) He makes the pope a temporal sovereign. By this time the bishop of Rome has become the largest landholder in Italy. The Lombard invasion has given the bishops opportunity for temporal control, and in Rome and its vicinity the people recognise Gregory at the head of affairs.
