once someone is added to Israel, they are no longer ... Jewish

I will let my posts speak for themselves. Someone who thinks Catholics keep the 10 commandments instead of the law of Christ, might not be the best judge of who a Catholic is. after all, Exodus 20:8-11 forbids working on the 7th day, our Saturday. when was the last time you heard any Catholic Bishop condemn Catholic major league ball players from playing on Saturday?

Such comments are contrary to the Catechism of the Catholic Church as well as the Scriptures.
1. Since the Ascension Christ's coming in glory has been imminent,566 even though "it is not for you to know times or seasons which the Father has fixed by his own authority."567. This eschatological coming could be accomplished at any moment, even if both it and the final trial that will precede it are "delayed".568 674 The glorious Messiah's coming is suspended at every moment of history until his recognition by "all Israel", for "a hardening has come upon part of Israel" in their "unbelief" toward Jesus.569 St. Peter says to the Jews of Jerusalem after Pentecost: "Repent therefore, and turn again, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord, and that he may send the Christ appointed for you, Jesus, whom heaven must receive until the time for establishing all that God spoke by the mouth of his holy prophets from of old."570 St. Paul echoes him: "For if their rejection means the reconciliation of the world, what will their acceptance mean but life from the dead?"571 The "full inclusion" of the Jews in the Messiah's salvation, in the wake of "the full number of the Gentiles",572 will enable the People of God to achieve "the measure of the stature of the fullness of Christ", in which "God may be all in all".573
2. The Council of Trent teaches that the Ten Commandments are obligatory for Christians and that the justified man is still bound to keep them;28 the Second Vatican Council confirms: "The bishops, successors of the apostles, receive from the Lord . . . the mission of teaching all peoples, and of preaching the Gospel to every creature, so that all men may attain salvation through faith, Baptism and the observance of the Commandments."29

[daniel1212]

Keeping the 10 commandments, and indeed the Law, means as under the New Covenant, in which the Holy Spirit distinguishes btwn universal transcendent moral laws and the typological ceremonial laws relating to physical diet, external cleanness and temple ritual, "Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation." (Hebrews 9:10) "Which are a shadow of things to come; but the body [which made the shadow] is of Christ." (Colossians 2:17)

And i have already spent much time on FR refuting those who impose ceremonial laws before, in which you found offense .

Thus believers look to Christ as the supreme standard, and thus obey Him under the new covenant He instituted with His own sinless shed blood, and neither commit adultery nor require circumcision, (cf. 1Cor. 7:18; Gal. 2:3) or remain unclean until the evening every time they have marital relations. (cf. Heb. 13:4) But they are to fulfill the holy intent of such (which requires keeping the full extent of the moral law in heart and deed, as well as the intent of the ceremonial), so "That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit." (Romans 8:4)

As regards Israel I have supplied some of these CCC citations before , and that is why i questioned the way some RCs talk as if Catholic teaching does not hold Jews as a special distinct people, and also referred to as Israel, for which God will do a special work of grace. Which relates to the Tribulation.

674 The glorious Messiah's coming is suspended at every moment of history until his recognition by "all Israel", for "a hardening has come upon part of Israel" in their "unbelief" toward Jesus.569 [ Rom 11:20-26; cf. Mt 23:39.]

"For if their rejection means the reconciliation of the world, what will their acceptance mean but life from the dead?"571[The "full inclusion" of the Jews in the Messiah's salvation, in the wake of "the full number of the Gentiles",572 will enable the People of God to achieve "the measure of the stature of the fullness of Christ", in which "God may be all in all".573

675 Before Christ's second coming the Church must pass through a final trial that will shake the faith of many believers.574 The persecution that accompanies her pilgrimage on earth575 will unveil the "mystery of iniquity" in the form of a religious deception offering men an apparent solution to their problems at the price of apostasy from the truth. The supreme religious deception is that of the Antichrist, a pseudo-messianism by which man glorifies himself in place of God and of his Messiah come in the flesh.576 -http://www.vatican.va/archive/ccc_css/archive/catechism/p1s2c2a7.htm
