proclaim

172. Why must the Church proclaim the Gospel to the whole world?
849-851
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).
