When Paul was at Corinth, and probably in A.D. 53, he wrote his two earliest letters, that is, the First and Second Epistles to the Thessalonians. These communications must, therefore, have been drawn up about twelve months after the original formation of the religious community to which they are addressed. The Thessalonian Church was already fully organised, as the apostle here points out to the disciples their duties to those who laboured among them and who were over them in the Lord. [113:3] In the meantime several errors had gained currency; and a letter, announcing that the day of Christ was at hand, and purporting to have been penned by Paul himself, had thrown the brethren into great consternation. [113:4] The apostle accordingly deemed it necessary to interpose, and to point out the dangerous character of the doctrines which had been so industriously promulgated. He now, too, delivered his famous prophecy announcing the revelation of the "Man of Sin" before the second coming of the Redeemer. [113:5] Almost all the members of the Thessalonian Church were probably converted Gentiles, [113:6] who must still have been but little acquainted with the Jewish Scriptures; and this is perhaps the reason why there is no quotation from the Old Testament in either of these letters. Even the Gospels do not seem to have been yet written, and hence Paul exhorts the brethren "to hold fast the traditions," or rather "ordinances," [114:1] which they had been taught, "whether by word or his epistle." [114:2] CHAPTER VIII. THE CONVERSION OF APOLLOS, HIS CHARACTER, AND THE MINISTRY OF PAUL IN EPHESUS. A.D. 54 TO A.D. 57. The Apostle "took his leave" [115:1] of the Corinthian brethren in the spring of A.D. 54, and embarking at the port of Cenchrea, about eight or nine miles distant, set sail for Ephesus. The navigation among the islands of the Greek Archipelago was somewhat intricate; and the voyage appears to have not unfrequently occupied from ten to fifteen days. [115:2] At Ephesus Paul "entered into the synagogue, and reasoned with the Jews." [115:3] His statements produced a favourable impression, and he was solicited to prolong his visit; but as he was on his way to Jerusalem, where he was anxious to be present at the approaching feast of Pentecost, he could only assure them of his intention to return, and then bid them farewell. He left behind him, however, in this great city his two Corinthian converts, Aquila and Priscilla, who carried on with industry and success the work which he had commenced so auspiciously. Among the first fruits of their pious care for the spread of Christianity was the famous Apollos, an Alexandrian Jew, who now arrived in the metropolis of the Proconsular Asia.
