The Persons Addressed. The Thessalonians inhabited the chief city of Macedonia. Macedonia was the first European country in which St. Paul preached, and he always regarded it with peculiar affection. In Acts 16:17 we have St. Luke's wonderfully vivid narrative of the bringing of the Gospel to Macedonia. After some stay at Philippi the Apostle went through Amphipolis and Apollonia to Thessalonica, where he stayed for some six months (Acts 17:1), preaching first to the Jews as usual, and afterwards winning many converts among Gentile proselytes and women as well as among the heathen. Jewish intrigue at length drove him away. This famous city of Thessalonica, originally called Therma, had been refounded by Cassander about 315 b.c., and, owing to its natural advantages, had grown and flourished. After the Roman conquest the great military road, the Via Egnatia, connected it with Italy and the East, while its fine harbour made it a great commercial centre. It was made a Free City by Augustus, with the privilege of self-government (Acts 17:6). At the present time, under the slightly altered name of Saloniki, it is the second city of the Turkish empire, with a population of 70,000. It contained (and still contains) a considerable number of Jews, and had a large native population. It was from this latter class that St. Paul's converts were chiefly drawn (cp. 1 Thessalonians 1:9; 1 Thessalonians 2:14, and observe the absence of OT. quotations), and it is plain that they had the characteristic virtues, as well as some of. the characteristic defects, of their race, which was brave, independent, persevering, and liberty-loving. But the Thessalonian converts sometimes allowed their independence to degenerate into undue self-assertion and disregard of authority (1 Thessalonians 5:14; 2 Thessalonians 3:6). Yet, on the whole, St. Paul was proud and fond of them. Notwithstanding terrible persecution, they had remained firm (1 Thessalonians 1:6; 1 Thessalonians 2:8; 1 Thessalonians 2:14; 2 Thessalonians 1:4). Though poor they were generous (2 Corinthians 8:1). Their influence was felt throughout Macedonia and Greece (1 Thessalonians 1:8). Their faith, hope, and love filled the Apostle's heart with joy (1 Thessalonians 1:2).
