The way in which Paul introduces Galatians 5:2-12 indicates the importance of what he is about to say. “Look” (ESV), “Listen!” (NRSV), “Mark my words!” (NIV), “I, Paul, say to you” (ESV). Paul is not fooling around. By his forceful use of the word look, he not only calls for his readers’ full attention, but he even evokes his apostolic authority. He wants them to understand that if the Gentiles are going to submit to circumcision to be saved, then the Galatians need to realize the dangerous consequences involved in their decision.
Read Galatians 5:2-12. What does Paul warn about in regard to the whole question of circumcision?
The first consequence of trying to earn God’s favor by submitting to circumcision is that it obligates the person to keep the entire law. Paul’s language in verses 2 and 3 includes an interesting play on words. Christ, he says, will not benefit them (ophelesei); rather, they will be obligated (opheiletes) to the law. If a person wants to live according to the law, he or she cannot just pick and choose the precepts to follow. It is all or nothing.
Second, they will be “cut off” from Christ. A decision to be justified by works involves at the same time a rejection of God’s way of justification in Christ. “You cannot have it both ways. It is impossible to receive Christ, thereby acknowledging that you cannot save yourself, and then receive circumcision, thereby claiming that you can.” — John R. W. Stott, The Message of Galatians (Leicester, England: InterVarsity Press, 1968), p. 133.
Paul’s third objection to circumcision is that it hinders spiritual growth. His analogy is of a runner whose progress toward the finish line has been deliberately sabotaged. In fact, the word translated “hindered” (vs. 7, ESV) was used in military circles to refer “to breaking up a road or destroying a bridge or placing obstacles in the way of an enemy, to halt his advance.” — The SDA Bible Commentary, vol. 6, p. 978.
Finally, circumcision removes the offense of the Cross. How? The message of circumcision implies that you can save yourself; as such, it is flattering to human pride. The message of the Cross, however, is offensive to human pride, because we have to acknowledge that we are dependent completely on Christ.
Paul is so outraged at these people for their insistence on circumcision that he says he wishes that the knife would slip and they would castrate themselves! Strong words, but Paul’s tone simply reflects how seriously he views this issue.
