Day 265 Ontologically Jewish?

What does it mean to be ontologically Jewish? Paul says all who are inwardly in Christ are Jewish. I suppose this is in keeping with our heritage in Jesus...King of the Jews. Here is how Paul states this thought..."For no one is a Jew who is merely one outwardly, nor is circumcision outward and physical. But a Jew is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the letter. His praise is not from man but from God." This understanding is also consistent with the circumcision of the heart is more needed than circumcision.
