Well, what, if anything, did the Council itself say in this point? In researching the textual history of the Vatican II Declaration on Non-Christian Religions, Nostra Aetate (NA), I have found that the original draft of article 4 in that document was actually quite up-front and positive about Catholic hopes for Jewish conversions to the true faith. It included this passage: “It is important to recall that the integration of the Jewish people into the Church is part of Christian hope. For, according to the Apostle’s teaching (cf. Rom. 11: 25), the Church awaits with unshakable faith and deep longing the entry of this people into the fullness of the People of God, which has been restored by Christ” (AS III, VIII, p. 640, my translation). In the biblical verse cited here, the Holy Spirit, through Saint Paul, speaks of the “blindness” of the unbelieving Jews as being temporary, and prophesies in the next verse the salvation of Israel as a nation, after the “fullness of the Gentiles” has come into the Church."
