Circumcise yourselves to the LORD, and take away the foreskins of your heart, you men of Judah and inhabitants of Jerusalem: lest my fury come forth like fire, and burn that none can quench it, because of the evil of your doings.
All Commentaries on Jeremiah 4:4 Go To Jeremiah 4
Tertullian of Carthage
AD 220
Paul mentioned “certain false brethren as having crept in secretly,” who wished to turn the Galatians to another gospel. He shows that that adulteration of the gospel was not meant to transfer them to the faith of another god and christ, but rather to perpetuate the teaching of the law. He blames them for maintaining circumcision and observing times, and days, and months and years, according to those Jewish ceremonies that they ought to have known were now abolished, according to the new dispensation willed by the Creator, who foretold in ancient times this very thing by his prophets. Thus he says by Isaiah: “Old things have passed away. Behold, I will do a new thing.” And in another passage: “I will make a new covenant, not according to the covenant that I made with their fathers, when I brought them out of the land of Egypt.” In the same he said by Jeremiah: Make to yourselves a new covenant, “circumcise yourselves to the Lord, and take away the foreskins of your heart.” It is this circumcision, therefore, and this renewal, that the apostle insisted on when he forbade those ancient ceremonies concerning which their very founder announced that they were one day to cease.
