I THESSALONIANS (First Epistle of Apostle Paul to the Thessalonians) – This epistle is probably the first of St. Paul’s letters, written from Corinth about 51 A.D. During his second missionary journey, after being driven out of Philippi, Paul, Silas and Timothy came to Thessalonica, the capital of Macedonia (Acts 17:1). Here he preached in the synagogue for three Sabbaths, proclaiming Jesus as the Messiah and attracting many followers, both Jews and Gentiles. The Jews, annoyed at these inroads, aroused such a disturbance, that Paul and his companions had to leave, going first to Beroea and thence to Athens and Corinth.
Paul, anxious about the new congregation at Thessalonica, deprived of his leadership and persecuted, sent Timothy to strengthen and encourage the young congregation. When Timothy returned with the good news of their faith and loyalty, Paul wrote the first letter to the Thessalonians to express his joy and gratitude at their perseverance, to urge them to Christian conduct, and to answer two questions: 1) Is a Christian deprived of the blessings of the Kingdom if he dies before Christ’s second Advent; and 2) When will Christ come in glory? The first is answered in 4:13-18 and the second in 5:1-11.
