Paul repeats an idea he said earlier in his letter (Galatians 5:6). For those who are united to Christ through faith, neither the works we do (for example, circumcision), nor the works we do not do (uncircumcision) play a role in our justification. 1 The marks we bear on our bodies do not testify whether or not we truly belong to God. The cross renders circumcision null and useless as a means of justification. 2
15 For neither circumcision counts for anything, nor uncircumcision, but a new creation.
