172. Why must the Church proclaim the Gospel to the whole world?

(Comp 172) The Church must do so because Christ has given the command: “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit” (Matthew 28:19). This missionary mandate of the Lord has its origin in the eternal love of God who has sent his Son and the Holy Spirit because “he desires all men to be saved and to come to the knowledge of the truth” (1 Timothy 2:4).

“In brief”

(CCC 868) The Church is catholic: she proclaims the fullness of the faith. She bears in herself and administers the totality of the means of salvation. She is sent out to all peoples. She speaks to all men. She encompasses all times. She is "missionary of her very nature" (AG 2).

To deepen and explain

(CCC 849) The missionary mandate. "Having been divinely sent to the nations that she might be 'the universal sacrament of salvation,' the Church, in obedience to the command of her founder and because it is demanded by her own essential universality, strives to preach the Gospel to all men" (AG 1; cf. Mt 16:15): "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you; and Lo, I am with you always, until the close of the age" (Mt 28:19-20). (CCC 850) The origin and purpose of mission. The Lord's missionary mandate is ultimately grounded in the eternal love of the Most Holy Trinity: "The Church on earth is by her nature missionary since, according to the plan of the Father, she has as her origin the mission of the Son and the Holy Spirit" (AG 2). The ultimate purpose of mission is none other than to make men share in the communion between the Father and the Son in their Spirit of love (Cf. John Paul II, RMiss 23).

On reflection

(CCC 851) Missionary motivation. It is from God's love for all men that the Church in every age receives both the obligation and the vigor of her missionary dynamism, "for the love of Christ urges us on" (2 Cor 5:14; cf. AA 6; RMiss 11). Indeed, God "desires all men to be saved and to come to the knowledge of the truth" (1 Tim 2:4); that is, God wills the salvation of everyone through the knowledge of the truth. Salvation is found in the truth. Those who obey the prompting of the Spirit of truth are already on the way of salvation. But the Church, to whom this truth has been entrusted, must go out to meet their desire, so as to bring them the truth. Because she believes in God's universal plan of salvation, the Church must be missionary.
