Matthew Poole and continuators on Galatians 1:6

6 I marvel that ye are so soon removed from him that called you unto the grace of Christ , unto another gospel .

The Apostle here beginneth the matter and substance of his Epistle, with a reprehension of this Church; which in some things is much qualified, in other things much aggravated. His expressing his reproof by the word marvel, hath in it something of mitigation, and signifieth his better hopes concerning them. The term removed, also mollifies the reproof, the Apostle thereby rather charging their Apostacy upon their seducers, then upon them who were seduced, (though they were not to be excused for their so yielding to the temptation, and that in so short a time, either after their first conversion, or after the first attempts upon them to seduce them) and herein was the aggravation of their guilt, that they very little resisted the temptation, but were presently overthrown by it. But it was a greater aggravation of their guilt, that they suffered themselves to be removed from him that called them. Interpreters doubt whether this be to be understood of God, or of Paul; and if of God, whether of the first or of the second person. That which inclineth some to think that Paul meant himself, was his instrumentality in the conversion of these Galatians; and his complaints of them in this Epistle, for their deserting his Doctrine and alienation from him: but then the substantive to the participle must be understood, and the call must be understood of the external call onely, by the Ministry of the word. It therefore seemeth rather to be understood of God; the Apostles generally ascribing calling to God; chap. 5.8. 1 Thess. 5.24. 2 Thess. 2.14. 1 Pet. 1.2.15. 2 Pet. 1.3. Nor doth it seem proper to refer the action to Christ, because the Apostles ordinarily ascribe calling to the first person in the Trinity, calling us by Christ, as Rom. 8.30. 2 Thess. 2.13, 14, 16. 2 Tim. 1.[illegible: 1 letter]9. 1 Pet. 5.10. besides the Grace of Christ is here made the term to which they are called. And though this would supply the participle with a substantive in the Text, without understanding one, yet it seems both too remote, and also to alter the sense of the Text; making it to run thus, from Christ that called you unto Grace, instead of him that called you to the Grace of Christ. By which Grace the Apostle doubtless means not the Doctrine of the Gospel onely, (though that be sometimes called Grace,) but all the benefits of the Gospel, Iustification, Reconciliation, Adoption: which are all properly called the Grace of Christ as being the purchase of his blood.

To another Gospel, that is to the imbracing of other Doctrine, differring from the Doctrine of the Gospel, though it be brought to you by seducers under that notion: shewing you another pretended way of Salvation then by the merits of Jesus Christ, whereas God hath given no other name under heaven, neither is there Salvation in any other, Acts 4.12.
