4. In my first encyclical, in which I set forth the program of my Pontificate, I said that "the Church's fundamental function in every age, and particularly in ours, is to direct man's gaze, to point the awareness and experience of the whole of humanity toward the mystery of Christ."4

The Church's universal mission is born of faith in Jesus Christ, as is stated in our Trinitarian profession of faith: "I believe in one Lord, Jesus Christ, the only Son of God, eternally begotten of the Father.... For us men and for our salvation he came down from heaven: by the power of the Holy spirit he became incarnate from the Virgin Mary, and was made man."⁵ The redemption event brings salvation to all, "for each one is included in the mystery of the redemption and with each one Christ has united himself forever through this mystery."⁶ It is only in faith that the Church's mission can be understood and only in faith that it finds its basis.

Nevertheless, also as a result of the changes which have taken place in modern times and the spread of new theological ideas, some people wonder: Is missionary work among non-Christians still relevant? Has it not been replaced by inter-religious dialogue? Is not human development an adequate goal of the Church's mission? Does not respect for conscience and for freedom exclude all efforts at conversion? Is it not possible to attain salvation in any religion? Why then should there be missionary activity?
