In accordance with the divine command, to preach the gospel to all the nations, beginning at Jerusalem, the apostles began their mission; and when the Jews rejected their message, they turned to the Gentiles, and went everywhere preaching the word “according to the revelation of the mystery, which was kept secret since the world began, but now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith,” Rom. 16:25, 26. The first converts to the faith, comprised “Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judea, and Cappadocia, in Pontus, and Asia, Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes, Cretes and Arabians,” Acts 2:9-12. When the Jews contradicted and blasphemed, “Paul and Barnabas waxed bold, and said, It was necessary that the word of God should first have been spoken to you: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the Gentiles,” Acts 13:46. Afterwards Paul, in writing to the Colossians, refers to the gospel as that “which was preached to every creature which is under heaven,” Col. 1:23. This gospel was to be preached to those who dwell on the earth, and also to all nations. The symbolic earth of the Apocalypse, being generally admitted to be the Roman empire under a quiet government, its fulfilment would require an early introduction of the gospel there. Accordingly we find, within thirty years after the crucifixion of Christ, a flourishing church existing in the metropolis of the Roman empire, to which Paul addressed one of his most able letters. In it, he thanks God that their “faith is spoken of throughout all the world,” Rom. 1:8. The apostle had then “fully preached the gospel of Christ” from Jerusalem “round about [the coast of the Mediterranean] unto Illyricum,” (Rom. 16:19);—a country on the Adriatic, or Gulf of Venice. He afterwards visited Rome, and is supposed to have preached the gospel as far west as Spain. The apostles spread Christianity throughout the Roman empire. Palestine, Syria, Natolia, Greece, the islands of the Mediterranean, Italy, and the northern coast of Africa, contained societies of Christians in the first century. In the second century societies existed, and Christ was worshipped, among the Germans, Spaniards, French, Celts, and Britons, and many other nations in Europe, and almost throughout the whole east. In the fourth century Christianity had become the prevailing religion of the empire.
