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.

Your quotes, from the same source, are quite contradictory.
