At the time of the Council of Nicæa (A.D. 325) the bishop of Rome's patriarchate was confined to the middle and the south of Italy, with the Islands of Sicily, Sardinia, and Corsica. It afterwards grew by degrees, until at length it took in all the countries of the west, although it had lost Illyricum, which was once a part of it. But this was not until long after the time to which our little book relates, and in the meanwhile its extent varied very much. The reason why its bounds, at the time of the Council of Chalcedon, or in the days of Gregory the Great, cannot well be marked in a map is, that in some countries the bishops of Rome had much _influence_, but had not _power_. They gave _advice_ to the bishops of Gaul (or France), Spain, and Africa, and sometimes ventured to give them _directions_. But they could not make the bishops of those countries obey their directions, and had not _authority_ over them in the same way as the patriarchs of Constantinople, Alexandria, Antioch, or Jerusalem had over the bishops within their patriarchates. To mark such countries as belonging to the Roman patriarchate would be too much; to mark them as if they had no connexion with it would be too little. SKETCHES OF CHURCH HISTORY. CHAPTER I. THE AGE OF THE APOSTLES. FROM A.D. 33 TO A.D. 100. The beginning of the Christian Church is reckoned from the great day on which the Holy Ghost came down, according as our Lord had promised to His Apostles. At that time, "Jews, devout men, out of every nation under heaven," were gathered together at Jerusalem, to keep the Feast of Pentecost (or Feast of Weeks), which was one of the three holy seasons at which God required His people to appear before Him in the place which He had chosen (_Deuteronomy_ xvi. 16). Many of these devout men were converted, by what they then saw and heard, to believe the Gospel; and, when they returned to their own countries, they carried back with them the news of the wonderful things which had taken place at Jerusalem. After this, the Apostles went forth "into all the world," as their Master had ordered them, to "preach the Gospel to every creature" (_St. Mark_ xvi. 15). The Book of Acts tells us something of what they did, and we may learn something more about it from the Epistles. And, although this be but a small part of the whole, it will give us a notion of the rest, if we consider that, while St. Paul was preaching in Asia Minor, in Greece, and at Rome, the other Apostles were busily doing the same work in other countries.
