During the eighteen months which St. Paul spent in Corinth, he appears to have written "The Epistle to the Galatians," which was probably written before that to the Thessalonians. St. Paul had, as we have heard, preached in Galatia before he went into Macedonia. It seems, however, that the Galatians had not continued steadfast in the faith; and the Apostle now writes kindly, to express his surprise at their having fallen away from the Gospel they had once received; warning them seriously not to believe any doctrines contrary to those which he had taught them: for that he had been chosen by the Lord in a miraculous manner to be an Apostle, and the doctrines which he taught to others he had received from God Himself. He also reminds the Galatians, that no man could obtain salvation by the works of the Law, since none could do them perfectly, and that it is through faith in Jesus only, that all men, whether Jews or Gentiles, can be saved. Before closing his Epistle, St. Paul gives a list of the works of the flesh, or sinful nature of man, and of the works of the Spirit. This list we shall do well to study, and also to take as addressed to ourselves the Apostle's exhortation, "Walk in the Spirit, and ye shall not fulfil the lust of the flesh": remembering always, that "they that are Christ's have crucified the flesh with the affections and lusts." From Corinth, at this time, St. Paul also wrote his Second Epistle to the Thessalonians; expressing his thankfulness that in the midst of persecutions they were increasing in faith; and he encourages them to persevere, by reminding them of that day when Christ shall come to judge the world, and reward the faithful with everlasting life. He then begged those to whom he wrote, to pray that the Gospel preached by him might be received by others as it had been by them; and he prays for them, that the Lord will "direct their hearts into the love of God, and into the patient waiting for Christ." St. Paul was not allowed to rest undisturbed at Corinth, for when Gallio was deputy-governor, or pro-consul, of Achaia, "the Jews made insurrection with one accord against Paul; and brought him to the judgment seat, saying, This fellow persuadeth men to worship God contrary to the law,"--meaning their own law, the Law of Moses. St. Paul was going to speak in answer to this charge, but Gallio interrupted him, and told the Jews that if they had any wickedness, or crime, to accuse St. Paul of, he must of course listen to the charge; and adding, "but if it be a question of words and names, and of your law, look ye to it; for I will be no judge of such matters." Gallio, a heathen, despised both Jews and Christians, and cared nothing about the Law of Moses, whether it were observed or not; therefore he would not listen to the Jews: "and he drave them from the judgment seat."
