加拉太书 Galatians

加拉太书是一封救火的信。保罗在加拉太地区建立教会后不久，就有一批「奉割礼的」教师跟进，宣称外邦信徒除了信基督，还必须受割礼、守摩西律法才能真正得救。教会迅速动摇，保罗闻讯震惊愤慨，连惯常的感恩问安都省去，开门见山地责备：「我希奇你们这么快离开那借着基督之恩召你们的，去从别的福音。」

保罗的回应分三步：先以亲身经历证明他的福音直接来自耶稣基督的启示，连彼得在真理上偏差时他也当面抵挡；再从圣经论证——亚伯拉罕因信称义早于律法四百三十年，律法是引人到基督面前的「训蒙的师傅」；最后指出真自由的生活：不是放纵情欲，而是凭信心、借圣灵结出仁爱喜乐和平的果子。

「基督释放了我们，叫我们得以自由」——加拉太书被称为「基督徒自由的大宪章」，马丁路德视之为「我的卡塔琳娜」（最亲爱的书信）。今天，靠表现赚取神悦纳的「律法主义」仍以各样形式潜入教会与人心；加拉太书一再把我们带回原点：得救本乎恩、因着信，并且「我已经与基督同钉十字架」。

Galatians is a letter written to put out a fire. Soon after Paul planted churches in the region of Galatia, teachers from the "circumcision group" moved in, insisting that Gentile believers must add circumcision and the law of Moses to faith in Christ in order to be truly saved. The churches were quickly swayed. Paul was so alarmed that he skipped his customary thanksgiving altogether and opened with a rebuke: I am astonished that you are so quickly deserting the one who called you by the grace of Christ and are turning to a different gospel.

His response unfolds in three movements. First, autobiography: his gospel came by direct revelation from Jesus Christ — he even opposed Peter to his face when Peter wavered. Second, Scripture: Abraham was justified by faith four hundred and thirty years before the law was given; the law served as a guardian to lead us to Christ. Third, life: true freedom is not license for the flesh but walking by the Spirit in faith, bearing the fruit of love, joy, and peace.

"It is for freedom that Christ has set us free." Galatians has been called the Magna Carta of Christian liberty; Luther cherished it so much he called it "my Katharina," after his wife. Legalism — earning God's acceptance by performance — still slips into churches and hearts in endless disguises. Galatians keeps pulling us back to the starting point: salvation is by grace through faith, and "I have been crucified with Christ and I no longer live, but Christ lives in me."
