Because they are both monotheistic or believe in one God....

In more elaborate terms, Catholics believe the Covenants the God of Israel made with that nation aren't dead: they are now held by the Gentiles and Jews within the Catholic Church which is the "New Zion". God still has a special plan for the Jewish people, but the Covenants of His Salvation and His Presence rest in the Temple of Christ in His Jerusalem: the Catholic Church.

Mandate of Israel*NONE. The Catholic religion is the antithesis of the Faith of Israel, which is the Faith of the Yeshua, the Maschiach of Israel. The catholic faith contravenes the Biblical intentions of the G-D of Israel. There is no evidence that the Mandate was taken away from Israel and given to the gentiles (church). If it were so, then it gives the lie to Yehua's claims that He was sent to redeem Israel. The G-D of Israel would also stand accused of reneging on that promise. The redemption of Israel was not only about their peoplehood, but also about retention of their MANDATE from Heaven.

*The first answer above would have contradicted the following

1. Yeshua's statement that "salvation is of the Jews". 2.Rabbi Shaul's statements that the covenants, the promises, the Offices, the Identity of the Congregation, Birthrights, Ranking, Authority, the Prophesies, the LAW, the Bible belongs to Israel.

Another AnswerJudaism is basically Catholicism's "older brother." Jesus and all the disciples were Jews originally. About that whole Mandate thing...

1. It's okay to say God, you don't have to blank that word word out like it's a cuss word or something.

2. God created everything and he loves it all, not just Israel and the Jews. They are his chosen people, but he does love the Gentiles too.

3. Who is Rabbi Shaul?

Mandate of IsraelOne of the probs in the last 2,000 years was the attempted gentilization of the true christian faith. Names were gentilize, places, ownerships, mandates, authority, offices. Rabbi Shaul is the Hebrew name of Paul of Tarsus. Us christians found it easier to claim Yeshua as ours rather than Israel's by turning the Bible and everything in it into a christian Book.

Imagine the Russians claiming that America belongs to them. They would change the place names into slavic, Washington, Lincoln,et al would become Russian communist heroes. Any protestations by Americans would be dealt with accordingly. American freedom and liberty values would be interpreted according to communist ideology.

Scary. And yet, that's exactly what happened what happened to the faith of Israel when the church tried to usurped Israel's Mandate. Yshua once said to Israel, that He would bring down a veil across the eyes of Israel so that they would recognize Him until the last days. I believe that veil is the Deceptions of the church. I once asked a Jew why they find it hard to accept Yeshua as our Lord, and he replied "that's just it, He's your's, not our's".

It turned out that he is right. Yeshua is in fact their Maschiach, not ours gentiles. The Office of the Maschiach belongs to the Congregation of Israel, not the church's.

Yeshua and all of his disciples were not just Jews originally, they stayed Jewish till the day they died. For them to become otherwise is actually to repudiate their covenants, their promises, and Yeshua Himself. For Yeshua to become the Lord of the church, He would have to throw away the TORAH upon w/c His own Office is embedded into. The Office of the Maschiach of Israel is in the Tanak as the Office of the Presidency of the United States of America is embedded in the US Constitution. The US Con. is owned by the American People. The Torah-Tanak is owned by Israel. Take away Israel, you take away the Torah-Tanak. If the Torah-Tanak is gone, the Office of the Maschiach disappears.

By the way, the US President must be an American CITIZEN to qualify for this Office. Likewise the Office of the Maschiach. He must be from the Tribe of Yehudah, of the Faith of the Congregation of Israel. After all, He is going to assume the Mantle of the Kingship of the Kingdom of Israel, the Office of the High Priest of the Congregation of Israel, the Office of the Chief Prophet (Spokesman) of the People of Israel.

Indeed, He loves humanity. This is the reason why Israel's Mandate was to be redeemed. The Mandate is a proof that humans are capable of becoming citizens of Heaven in HIS own terms, not our's. The Torah is the minimum requrement that G-D had revealed to us to pass the QUALIFICATIONS for the Eternal Life. If Israel fails in that, then G-D has no reason to keep us humans in existence. Israel is suppossed to be the LIGHTBRINGER. The Adversary wants Israel to fail to prove that G-D, Lord and Master of the Universe, is not who He claims to be. Pls.read the hidden History of the church and antisemitism. I assure you, you will be stunned as Yokanan of the Book Revelation was when he was shown who and what the Queen of Heaven really is.

Catholicism is actually the opposite of the Faith of Yeshua. I know, I grow up as an RC.

What?Catholics do not believe in three gods. Catholics believe in 3 people, 1 God. This is a confusing bit of theology, so St. Patrick explained it like this:

Think of a 3-leaf clover. There are 3 leaves all connected to make the clover.

Or

3 people who are so united and have so powerful a love that they are as one.

Whoa!It is extremely misleading and inaccurate to say ... "There is no evidence that the Mandate was taken away from Israel and given to the gentiles (church). If it were so, then it gives the lie to Yehua's claims that He was sent to redeem Israel. The G-D of Israel would also stand accused of reneging on that promise."

Catholics consider that The God of Israel is the same God as that of the Catholic Church and that He has alreadylived up to His promise to redeem the Israelites, as was manifested in the very actions of the 12 Apostles, when Christ ordered them to go forth and teach all nations and so they did ... teaching all that Christ taught them; teachings which became the foundation of the Catholic Church itself. The 12 Apostles, (all previously Jews before their conversions) and their followers became the redeemed Jews as did everyone of the Jewish population who was baptised in the River Jordan, along with Christ himself, (baptised by John the Baptist), and thereby entered into the faith of Christ. In this way Catholics consider that the Jewish people received their redemption.

Those who did not convert and embrace the Sacrament of Baptism adhered to the old Jewish faith and denounced Christ and called for His crucifixion. Their descendants represent the current-day Jewish faith, which does not acknowledge that Christ was the Son of God, only that he was a prophet.

The Old Testament, (The Patriarchal Books) of the two religions are very similar, for they deal with the time before Christ and speak of the same Patriarchs for both religions. The Gentiles (founders of Catholicism) embraced Christ as their God, believing that he fulfilled the word of the Patriarchs of Israel, having been born through the line of the Patriarchs of Israel which both the Jewish and Catholic faiths acknowledge as their true Patriarchs. However the Books of the New Testament, which the Jewish faith does not accept, relate to the time following the birth of Christ, when the Jewish followers were split in their beliefs by the teachings of Christ.
