“If we go back to the beginnings of the Church, we find a clear affirmation that Christ is the one Savior of all, the only one able to reveal God and lead to God. In reply to the Jewish religious authorities who question the apostles about the healing of the lame man, Peter says: “By the name of Jesus Christ of Nazareth whom you crucified, whom God raised from the dead, by him this man is standing before you well… And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved” (Acts 4:10, 12). This statement, which was made to the Sanhedrin, has a universal value, since for all people-Jews and Gentiles alike - salvation can only come from Jesus Christ” (Redemptoris Missio).
“Faith demands a free adherence on the part of man, but at the same time faith must also be offered to him, because the multitudes have the right to know the riches of the mystery of Christ-riches in which we believe that the whole of humanity can find, in unsuspected fullness, everything that it is gropingly searching for concerning God, man and his destiny, life and death, and truth… This is why the Church keeps her missionary spirit alive, and even wishes to intensify it in the moment of history in which we are living. But it must also be stated, again with the Council, that in accordance with their dignity as persons, equipped with reason and free will and endowed with personal responsibility, all are impelled by their own nature and are bound by a moral obligation to seek truth, above all religious truth. They are further bound to hold to the truth once it is known, and to regulate their whole lives by its demands” (Redemptoris Missio).
“While acknowledging that God loves all people and grants them the possibility of being saved (cf. l Tm 2:4), the Church believes that God has established Christ as the one mediator and that she herself has been established as the universal sacrament of salvation. To this catholic unity of the people of God, therefore,…all are called, and they belong to it or are ordered to it in various ways, whether they be Catholic faithful or others who believe in Christ or finally all people everywhere who by the grace of God are called to salvation. It is necessary to keep these two truths together, namely, the real possibility of salvation in Christ for all mankind and the necessity of the Church for salvation. Both these truths help us to understand the one mystery of salvation, so that we can come to know God’s mercy and our own responsibility. Salvation, which always remains a gift of the Holy Spirit, requires man’s cooperation, both to save himself and to save others. This is God’s will, and this is **why he established the Church and made her a part of his plan of salvation.” ** (Redemptoris Missio)
