This was not a new claim: in about 446 Pope Leo I had expressly claimed authority over the whole Church: "The care of the universal Church should converge towards Peter's one seat, and nothing anywhere should be separated from its Head."
Contra 446 o papa León I reivindicou expresamente a súa autoridade sobre toda a Igrexa: "O coidado da Igrexa universal debe converxer para a cadeira de Pedro, e nada debe estar separado da súa cabeza".
