Tertullian, about the end of the second century, exclaims: "From no other cause have heresies arisen and schisms sprung up, except from a want of obedience to the priest of God, and because they do not remember that there is one judge for the time being in the Church, in the place of Christ." {225} The great and general Council of Nice, A.D. 325, in one of its canons says: "The Roman Church has always held the Primacy." The Council of Sardica, in a letter to the Pope, says: "This seems excellent and most suitable, that the priests of the Lord from the respective provinces should report to the Head," __i.e.__, to the See of the Apostle Peter. In the fifth century, all the Bishops of the province of Aries, in France, in a letter to Pope Leo, say: "The Holy Roman Church, through the most blessed Peter, Prince of the Apostles, has the principality above all the churches of the world." The grand Council of Chalcedon, where six hundred Bishops were present, mostly from the East, and out of the limits of the particular patriarchate of Rome, when the letter of the same Pope Leo was read, defining the faith of two distinct natures, divine and human, in Christ, exclaimed with one voice, "Peter has spoken by the mouth of Leo." At the beginning of the sixth century, the Bishop of Patara said to the Emperor Justinian: "There may be many sovereigns on the earth; but there is one Pope over all the churches of the universe." Not only Christian bishops and councils speak in this way of the Roman See, but emperors, and even pagans, use the same language. {226} In the year 268, when Paul, Patriarch of Antioch, was condemned of heresy by a council, the pagan Emperor Aurelian directed that the Church of Antioch "should be delivered up to those whom the Bishops of Italy and the Bishop of Rome should appoint." Ammianus Marcellinus, a pagan writer of the fourth century, affirms that "the Bishops of the Eternal City enjoy a greater authority." The Christian Emperor Valentinian, in a decree of the year 455, says: "The merit of the blessed Peter, who is the Prince of priestly order, and the dignity of the Roman city, the authority also of the Synod, strengthened the Primacy of the Apostolic See." These testimonies extend from the sixth back to the second century, when the disciples of the Apostles still lived. They are not merely the testimonies of the Bishops of Rome themselves, or of those who lived in the vicinity and under the immediate influence of Rome, but they are collected from Italy, France, Africa, and the whole Eastern Church, where those great Patriarchs flourished who afterwards renounced their subjection to Rome. Thus, it is evident, from these and a host of similar testimonies, that, during the first six centuries, the Bishops of Rome claimed to exercise the supremacy in the place of Peter, and that this claim was universally acknowledged. {227}
