In all these vital truths Paul's gospel was traversed by the Legalism countenanced by Peter at Antioch. _The Judaistic doctrine struck_ directly, if not avowedly, _at the cross_, whose reproach its promoters sought to escape. This charge is the climax of the Apostle's contention against Peter, and the starting-point of his expostulation with the Galatians in the following chapter. "If righteousness could be obtained by way of law, then Christ died for nought!" What could one say worse of any doctrine or policy, than that it led to this? And if works of law actually justify men, and circumcision is allowed to make a difference between Jew and Greek before God, the principle of legalism is admitted, and the intolerable consequence ensues which Paul denounces. What did Christ die for, if men are able to redeem themselves after this fashion? How can any one dare to build up in face of the cross his paltry edifice of self-wrought goodness, and say by doing so that the expiation of Calvary was superfluous and that Jesus Christ might have spared Himself all that trouble! And so, on the one hand, Legalism _impugns the grace of God_. It puts human relations to God on the footing of a debtor and creditor account; it claims for man a ground for boasting in himself (Rom. iv. 1-4), and takes from God the glory of His grace. In its devotion to statute and ordinance, it misses the soul of obedience--the love of God, only to be awakened by the knowledge of His love to us (ch. v. 14; 1 John iv. 7-11). It sacrifices the Father in God to the King. It forgets that trust is the first duty of a rational creature toward his Maker, that the law of faith lies at the basis of all law for man. On the other hand, and by the same necessity, Legalism is _fatal to the spiritual life in man_. Whilst it clouds the Divine character, it dwarfs and petrifies the human. What becomes of the sublime mystery of the life hid with Christ in God, if its existence is made contingent on circumcision and ritual performance? To men who put "meat and drink" on a level with "righteousness and peace and joy in the Holy Ghost," or in their intercourse with fellow-Christians set points of ceremony above justice, mercy, and faith, the very idea of a spiritual kingdom of God is wanting. The religion of Jesus and of Paul regenerates the heart, and from that centre regulates and hallows the whole ongoing of life. Legalism guards the mouth, the hands, the senses, and imagines that through these it can drill the man into the Divine order. The latter theory makes religion a mechanical system; the former conceives it as an inward, organic life. _THE DOCTRINAL POLEMIC._ CHAP. iii. 1-v. 12. CHAPTER XI. _THE GALATIAN FOLLY._
