No, this is your false doctrine.You keep repeating your refuted false doctrine. The Old Testament says converts to Judaism are Israel. And, that people who don't follow Judaism are not Israel. The New Testament teaches that Christians are citizens of Israel and heirs to the promises to Abraham.
Since I am the preacher, yes, that is precisely what I preach on the great pattern. The term "father" or patros in Greek refers to "source" and/or conveys similarities or likeness. Abraham is set forth in Romans 4 as an illustration to prove Paul's point in Romans 3:27-28 that it is by the law of faith that man is justified rather than by the law of works as the law of works provides grounds for boasting or glorying (same Greek word). It is the SIMILARITY or LIKENESS of Abraham's own personal justification by faith without works that Paul sets forth as the great pattern for all who are justified by faith, and thus Abraham is the "father" of all who are of faith in that sense.The promise is to Abraham and his seed (which is Christ). It's meaningless for you to wave you hand and say the promise is to gentiles because of "pattern". Does your preacher ever preach on the great "Pattern"?
Try the truth. Paul says, "For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: But he is a Jew, which is one inwardly; and circumcision is that of the heart." First, note the definition of a so-called Jew given by Paul, one who is circumcised in the flesh, not one who is (second born) from the loin of Abraham. Second, Paul does not define a true Jew as one additionally circumcised in the heart. A true Jew only is one circumcised of the heart, period
Yes, why don't you try the truth! In context, Paul is speaking exclusively about the Israelite who claims based upon obedience to the Law they will be justiifed. But Paul denies they are doers of the law, but are hypocrits (Rom.2:17-23). The true Jew/Israelite is both a Jew outwardly and inwardly, one who is by physical birth an Israelite and one who is by new birth a child of God - that is a true Jew. However, "in Christ" there is no "Jew". So Paul, when speaking about a "true" Jew is referring to a born again Israelite in contrast to a born again Gentile as this ethnic distinction is purely external with regard to the person not with the new birth.
