You are 40 years to late. From lumen gentium, the dogmatic constitution of the church:
http://en.wikipedia.org/wiki/Lumen_Gentium
One of the key portions of Lumen Gentium is its second chapter, with its declaration that the Church is "the People of God":
At all times and in every race God has given welcome to who so ever fears Him and does what is right. God, however, does not make men holy and save them merely as individuals, without bond or link between one another. Rather has it pleased Him to bring men together as one people, a people which acknowledges Him in truth and serves Him in holiness… Christ instituted this new covenant, the new testament, that is to say, in His Blood, calling together a people made up of Jew and gentile, making them one, not according to the flesh but in the Spirit. This was to be the new People of God. For those who believe in Christ, who are reborn not from a perishable but from an imperishable seed through the word of the living God, not from the flesh but from water and the Holy Spirit, are finally established as "a chosen race, a royal priesthood, a holy nation, a purchased people . . . who in times past were not a people, but are now the people of God". (LG 9)
In the second chapter, the Council teaches that God wills to save people not just as individuals but as a people. For this reason God chose the Israelite people to be his own people and established a covenant with it, as a preparation and figure of the covenant ratified in Christ that constitutes the new People of God, which would be one, not according to the flesh, but in the Spirit and which is called the Church of Christ (Lumen Gentium, 9).
All human beings are called to belong to the Church. Not all are fully incorporated into the Church, but "the Church knows that she is joined in many ways to the baptized who are honored by the name of Christ, but who do not however profess the Catholic faith in its entirety or have not preserved unity or communion under the successor of Peter" (Lumen Gentium, 15) and even with "those who have not yet received the Gospel," among whom Jews and Muslims are explicitly mentioned (Lumen Gentium, 16). The idea of any opening toward Protestantism caused a major controversy among traditionalist Catholic groups.
