Gálatas 6

Gálatas 6:13

The former circumcision was not inappropriate in its own time. But the law announced that Christ would come to dispense the law of freedom. Then the circumcision in the flesh would no longer be of service in the time of Christ. For through Christ came the true One of which the law was a shadow. From now on those who have been sealed with circumcision, even if they keep the whole law, would no longer gain any credit from their keeping this part of the law. … Nevertheless, the law is good and in its time so is circumcision, since through both we know Christ, who is the more perfect law and the more perfect circumcision. — PANARION 42.12.3, EIGHTH REFUTATION OF MARCION
