First Group, First and Second Thessalonians. "These Epistles are short, simple, and practical. They may be regarded as illustrating Paul's earlier missionary instruction to his converts--hence the name 'Missionary Epistles,' sometimes applied to them. They treat of but one doctrinal subject--the second coming of Christ." It should be borne in mind, however, that Paul speaks of Jesus Christ as "The Lord," "Our Lord," about twenty-five times in First Thessalonians; this shows how thoroughly he believed in the Deity of Christ. Second Group, Galatians, First and Second Corinthians and Romans. "This group is the great repertory of Paul's doctrinal and ethical teaching. Galatians and Romans deal chiefly with his doctrine of justification by faith. They are designed to disprove the current Jewish teaching (which was invading the churches) that men might be saved by obedience to the Mosaic law. On the contrary Paul maintained that the sole basis of salvation is the grace of God to be appropriated by faith on man's part." Third Group, Colossians, Philemon, Ephesians, and Philippians. "This group is predominantly Christological. Errors had invaded the churches addressed, which tended to degrade the person and work of Christ, and the Apostle writes with a view to showing his pre-eminence and saving power, so that the readers may be induced to keep their allegiance to Christ and His gospel." Fourth Group, First Timothy, Titus and Second Timothy. "These are called 'The Pastoral Epistles,' and were designed to instruct Timothy and Titus as superintendents of the churches in Ephesus and Crete, and were thus semi-official in character. But they have also a strong personal element and a tone of warm sympathy and affection." The above characterization of the four groups of these Epistles by Prof. G. B. Stevens is brief and to the point. +Common Plan.+--The plan in all of Paul's Epistles, with slight variations, is much the same. The outlines of these letters fall uniformly into six divisions. "First, a greeting sometimes very brief, sometimes extending over several verses, in which he generally manages with consummate skill to strike the keynote of the whole letter. Secondly, a thanksgiving to God for the Christian gifts and graces of his converts. Thirdly, a doctrinal part, in which he argues out or explains some great topic of Christian truth, specially required by the condition of the church to which he is writing. Fourthly, a practical section, in which he applies to daily moral duties the great doctrines which he has developed. Fifthly, personal messages, salutations, and details. Sixthly, a brief autograph conclusion to ratify the genuineness of the entire letter." +The Supreme Purpose+ was to make known the Divine Christ as the Savior of all men, both Jew and Gentile (1 Cor. 2:1-16; Col. 1:9-29; Phil. 2:9-11; Acts 26:22, 23; Rom. 3:9-31).
