Law and covenant have been entirely changed. God changed the first pact with Adam, and gave a new one to Noah. He gave another to Abraham, and changed this to give a new one to Moses. When the covenant with Moses was no longer observed, he gave another pact in this last age, a pact never again to be changed. He established a new law for Adam, that he could not eat of the tree of life. He gave to Noah the sign of the rainbow in the clouds. He then gave Abraham, chosen for his faith, the mark and seal of circumcision for his descendants. Moses was given the Passover lamb, the propitiation for the people. All these covenants were different from each other. Moreover, the circumcision that is approved by the giver of those covenants is the kind spoken of by Jeremiah: Circumcise your hearts. If God’s pact with Abraham was firm, so also is this covenant firm and trustworthy, nor can any other law be laid down, whether it originates outside the law or among those subject to the law.
