Genre
Like the rest of the Pauline letters, Galatians follows the conventions of letter writing in NT times. There is a salutation, a body, a paraenesis (set of moral exhortations), greetings, and a benediction. There is no initial thanksgiving, however, which indicates Paul’s agitation and alarm over the theological situation in Galatia. Paul gets right to the point, which is that the Galatians are in danger of turning to a different gospel, thereby risking the everlasting ruin of their souls. The main argument of the epistle is advanced by the use of autobiography, example, allegory, satiric rebuke, and exhortation.
The doctrinal thrust of Galatians gives it a strong internal unity. In one way or another, everything in the epistle is related to Paul’s defense of justification by faith alone. The letter is also unified by the apostle’s intensity of tone, which comes through as strongly here as it does in any of his writings—especially in his intolerance of false doctrine and his indignation with people who promote it. Stylistically, Galatians finds literary coherence in its thematic contrasts: the true gospel vs. a false gospel, faith vs. works, law vs. grace, liberty vs. legalism, sonship vs. slavery, and the fruit of the Spirit vs. the desires of the flesh.
Setting
“Galatia” was originally a Celtic region in north central Asia Minor (modern Turkey). It became a client kingdom of Rome under Pompey (mid-1st century B.C.). With the death of the client king Amyntas (d. 25 B.C.) an expanded Galatia came under a Roman governor. In Paul’s day the province of Galatia included parts of Pontus and Paphlagonia to the east and north and encompassed portions of Phrygia, Pisidia, Isauria, Lycaonia, and Cilicia to the south. Thus many of the cities of Paul’s first missionary journey (Acts 13–14) were considered part of the province of Galatia (or at least near its sphere of influence). Starting with territorial alterations under the emperor Vespasian (end of the 1st century A.D.), the province changed shape; thus the other ethnic territories were gradually drawn off, back to their earlier affiliations, and the province of Galatia returned to its more ethnically defined northern boundaries. Some contend that these subsequent reductions to the province of Galatia influenced the later church fathers to assume that Paul wrote his epistle to residents of northern Galatia. Archaeological evidence indicates a combination of Hellenistic, Celtic, and Roman influences in the province of Paul’s time.
