This term denotes the Galatians, inhabitants of the region of Galatia in central Asia Minor and recipients of Paul's epistle. Originally, Galatai was synonymous with Keltai (Celts), referring to Celtic peoples who migrated to Asia Minor in the 3rd century BC. In Galatians 3:1, Paul addresses them with the vocative, expressing frustration at their quick turn from grace to legalism. The translations preserve the ethnic designation (Spanish Gálatas, French/German retaining or adapting the Greek), recognizing these believers as the specific audience of Paul's impassioned defense of justification by faith.
