Cyprian of Carthage, Three Books of Testimonies Against the Jews I.9: That the first circumcision of the flesh is made void, and the second circumcision of the spirit is promised instead

8. That the first circumcision of the flesh is made void, and the second circumcision of the spirit is promised instead.

In Jeremiah: “Thus saith the Lord to the men of Judah, and to them who inhabit Jerusalem, Renew newness among you, and do not sow among thorns: circumcise yourselves to your God, and circumcise the foreskin of your heart; lest my anger go forth like fire, and burn you up, and there be none to extinguish it.” Also Moses says: “In the last days God will circumcise thy heart, and the heart of thy seed, to love the Lord thy God.” Also in Jesus the son of Nave: “And the Lord said unto Jesus, Make thee small knives of stone, very sharp, and set about to circumcise the children of Israel for the second time.” Paul also, to the Colossians: “Ye are circumcised with the circumcision not made with hands in the putting off of the flesh, but with the circumcision of Christ.” Also, because Adam was first made by God uncircumcised, and righteous Abel, and Enoch, who pleased God and was translated; and Noah, who, when the world and men were perishing on account of transgressions, was chosen alone, that in him the human race might be preserved; and Melchizedek, the priest according to whose order Christ was promised. Then, because that sign did not avail women, but all are sealed by the sign of the Lord.
