Others on The True Israel of God

Justyn Martyr:   "Jesus Christ ... is the new law, and the new covenant, and the expectation of those who out of every people wait for the good things of God. For the true spiritual Israel, and the descendants of Judah, Jacob, Isaac, and Abraham (who in uncircumcision was approved of and blessed by God on account of his faith, and called the father of many nations), are we who have been led to God through this crucified Christ."

John Calvin:  "Upon the Israel of God. This is an indirect ridicule of the vain boasting of the false apostles, who vaunted of being the descendants of Abraham according to the flesh. There are two classes who bear this name, a pretended Israel, which appears to be so in the sight of men, and the Israel of God. Circumcision was a disguise before men, but regeneration is a truth before God. In a word, he gives the appellation of the Israel of God to those whom he formerly denominated the children of Abraham by faith (Galatians 3:29), and thus includes all believers, whether Jews or Gentiles, who were united into one church."
