Galatians was written but slightly before (or after?) the letters to Thessalonica. Its single theme (after the retrospect) is the Adoption to Son ship through the Spirit. Against the Judaizer's plea that to share in the Inheritance one must be adopted (preferably by circumcision) into the family of Abraham, or at all events pay respect to the Mosaic Law, Paul asserts the single fact of the adoption of the Spirit. "It is because ye are sons that God sent forth the Spirit of his Son into our hearts crying (in the ecstatic utterances of 'tongues') Abba, that is, Father" (Gal. iv. 6). To go back to legal observances is to revert from redemption to bondage. All Christians are indeed sons of Abraham, but only as sharers of his trust in God. Abraham was made "heir of the world" (Rom. iv. 13) for his faith. Circumcision and the Law came afterwards. They were not superimposed stipulations and conditions of the promise. On the contrary they were temporary pedagogic measures intended to produce the consciousness of sin and (moral) death, so that when the Heir should come men should be ready to cast themselves on the mercy of God displayed in his vicarious death.[14] Thus the messianic Redemption is a redemption from a system issuing in sin and death. On the cross even the sinless Christ incurred the curse in order that believers thus redeemed might have the Blessing of the Abrahamic promise (Gal. iii. 1--iv. 7). Footnote 14: Romans enlarges the conception of the economy of Law by making it include the Gentile law of 'conscience' (Rom. i. 18--ii. 16). In Galatians this point is covered only by classing the "angels" through whom the Mosaic Law was given, with the "Elements" honoured in Gentile religion. Both are codes of "stewards and governors." But this transfer from bondage to liberty, from the legal to the filial relation, does not "make Christ a minister of sin." On the contrary, if the delivering Spirit of Son ship has been received at all, it controls the life for purity and love. One cannot be a son and be unfilial or unbrotherly. The unity of the redeemed world in Christ is the unity of loving service, not of subjection to a bygone system of rules (iv. 8--vi. 18). Thus does Galatians meet the insidious plea of the Judaizers, and their charges against Pauline liberty.
