A 210-page document titled “The Jewish People and the Holy Scriptures in the Christian Bible,” by the Pontifical Biblical Commission and authorized by the Vatican’s top theologian, Cardinal Joseph Ratzinger, reportedly states that “the Jewish messianic wait is not in vain.”
It reportedly says Jews and Christians share their wait for the Messiah, although Jews are waiting for the first coming and Christians for the second.
The new document also reportedly contains an apology to the Jewish people for anti-Semitic passages contained in the New Testament, and also stresses the continuing importance of the Torah for Christians.
Duh. Jesus is the Jewish Messiah, and He's coming back. "For I would not have you ignorant, brethren, of this mystery (lest you should be wise in your own conceits) that blindness in part has happened in Israel, until the fulness of the Gentiles should come in. And so all Israel should be saved, as it is written: There shall come out of Sion, he that shall deliver and shall turn away ungodliness from Jacob." (Rom 11:25-26).
Of course that doesn't mean that the Jews have a valid reason to reject their Messiah, or his historical form, the Church...
Indeed, the Church, guided by charity and respect for freedom, must be primarily committed to proclaiming to all people the truth definitively revealed by the Lord, and to announcing the necessity of conversion to Jesus Christ and of adherence to the Church through Baptism and the other sacraments, in order to participate fully in communion with God, the Father, Son and Holy Spirit. Thus, the certainty of the universal salvific will of God does not diminish, but rather increases the duty and urgency of the proclamation of salvation and of conversion to the Lord Jesus Christ. - Cardinal Ratzinger
And, looking at the quote:
Insistence on discontinuity between both Testaments and going beyond former perspectives should not, however, lead to a one-sided spiritualisation. What has already been accomplished in Christ must yet be accomplished in us and in the world. The definitive fulfilment will be at the end with the resurrection of the dead, a new heaven and a new earth. Jewish messianic expectation is not in vain. It can become for us Christians a powerful stimulant to keep alive the eschatological dimension of our faith. Like them, we too live in expectation. The difference is that for us the One who is to come will have the traits of the Jesus who has already come and is already present and active among us.
This looks to me like the "Jewish messianic expectation" is actually referring to the attitude maintained before the coming of Christ, and the point is that Jesus is the fulfillment of that expectation. Hardly what you implied. Another quote:
These Jews call the Christian faith into question; they do not accept that Jesus is their Messiah (Christ) and the Son of God. Christians cannot but contest the position of these Jews.
