Redemptoris Missio §11

¹¹ What then should be said of the objections already mentioned regarding the mission ad gentes ? While respecting the beliefs and sensitivities of all, we must first clearly affirm our faith in Christ, the one Savior of mankind, a faith we have received as a gift from on high, not as a result of any merit of our own. We say with Paul, "I am not ashamed of the Gospel: it is the power of God for salvation to everyone who has faith" (Rom 1:16). Christian martyrs of all times - including our own - have given and continue to give their lives in order to bear witness to this faith, in the conviction that every human being needs Jesus Christ, who has conquered sin and death and reconciled mankind to God. Confirming his words by miracles and by his resurrection from the dead, Christ proclaimed himself to be the Son of God dwelling in intimate union with the Father, and was recognized as such by his disciples. The Church offers mankind the Gospel, that prophetic message which responds to the needs and aspirations of the human heart and always remains "Good News." The Church cannot fail to proclaim that Jesus came to reveal the face of God and to merit salvation for all humanity by his cross and resurrection. To the question, " why mission? " we reply with the Church's faith and experience that true liberation consists in opening oneself to the love of Christ. In him, and only in him, are we set free from all alienation and doubt, from slavery to the power of sin and death. Christ is truly "our peace" (Eph 2:14); "the love of Christ impels us" (2 Cor 5:14), giving meaning and joy to our life. Mission is an issue of faith , an accurate indicator of our faith in Christ and his love for us. The temptation today is to reduce Christianity to merely human wisdom, a pseudo-science of well-being. In our heavily secularized world a "gradual secularization of salvation" has taken place, so that people strive for the good of man, but man who is truncated, reduced to his merely horizontal dimension. We know, however, that Jesus came to bring integral salvation, one which embraces the whole person and all mankind, and opens up the wondrous prospect of divine filiation. Why mission? Because to us, as to St. Paul, "this grace was given, to preach to the Gentiles the unsearchable riches of Christ" (Eph 3:8). Newness of life in him is the "Good News" for men and women of every age: all are called to it and destined for it. Indeed, all people are searching for it, albeit at times in a confused way, and have a right to know the value of this gift and to approach it freely. The Church, and every individual Christian within her, may not keep hidden or monopolize this newness and richness which has been received from God's bounty in order to be communicated to all mankind. This is why the Church's mission derives not only from the Lord's mandate but also from the profound demands of God's life within us. Those who are incorporated in the Catholic Church ought to sense their privilege and for that very reason their greater obligation of bearing witness to the faith and to the Christian life as a service to their brothers and sisters and as a fitting response to God. They should be ever mindful that "they owe their distinguished status not to their own merits but to Christ's special grace; and if they fail to respond to this grace in thought, word and deed, not only will they not be saved, they will be judged more severely."
