For in Jesus Christ neither circumcision avails anything, nor uncircumcision; but faith which works by love.
All Commentaries on Galatians 5:6 Go To Galatians 5
John Chrysostom
AD 407
Observe the great boldness with which he now encounters them; Let him that has put on Christ, he says, no longer be careful about such matters. Having before said that Circumcision was hurtful, how is it that he now considers it indifferent? It is indifferent as to those who had it previously to the Faith, but not as to those who are circumcised after the Faith was given. Observe too the view in which he places it, by setting it by the side of Uncircumcision; it is Faith that makes the difference. As in the selection of wrestlers, whether they be hook-nosed or flat-nosed, black or white, is of no importance in their trial, it is only necessary to seek that they be strong and skilful; so all these bodily accidents do not injure one who is to be enrolled under the New Covenant, nor does their presence assist him.
What is the meaning of working through love? Here he gives them a hard blow, by showing that this error had crept in because the love of Christ had not been rooted within them. For to believe is not all that is required, but also to abide in love. It is as if he had said, Had you loved Christ as you ought, you would not have deserted to bondage, nor abandoned Him who redeemed you, nor treated with contumely Him who gave you freedom. Here he also hints at those who have plotted against them, implying that they would not have dared to do so, had they felt affection towards them. He wishes too by these words to correct their course of life.
