And because of false brethren brought in unawares, who came in secretly to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:
All Commentaries on Galatians 2:4 Go To Galatians 2
John Chrysostom
AD 407
Who came in privily to spy out our liberty, which we have in Christ Jesus, that they might bring us into bondage.
He points out their hostility by calling them spies; for the sole object of a spy is to obtain for himself facilities of devastation and destruction, by becoming acquainted with his adversary's position. And this is what those did, who wished to bring the disciples back to their old servitude. Hence too appears how very contrary their purpose was to that of the Apostles; the latter made concessions that they might gradually extricate them from their servitude, but the former plotted to subject them to one more severe. Therefore they looked round and observed accurately and made themselves busybodies to find out who were uncircumcised; as Paul says, they came in privily to spy out our liberty, thus pointing out their machinations not only by the term spies, but by this expression of a furtive entrance and creeping in.
