Christ sent His Apostles, and all future missionaries, to preach to the whole world.
THE ELEVEN APOSTLES were with Christ in familiar surroundings in Galilee when they received the commission to establish, maintain, govern, and propagate the Kingdom of Christ throughout the whole world, until the end of time. For this mission Christ gave His own power to Peter, His Vicar, and to the Apostles; and He promised to remain with them. In a very short time the flock of Christ would be composed of peoples of every race and country; all members of the Church would be His disciples, just as much as were those faithful few during His own lifetime; and entry into the Church would be through faith and Baptism.
The Apostles went forth throughout the known world, and their successors have done the same in each generation. And so today Catholic missionaries are in every section of the world, attempting to form Christ in the hearts and souls of their hearers.
It is probable that we will never be able personally to join them in their labors, but we will want to help them, for every Christian, in loving Christ, desires everyone to love Him. Pope Pius XII has said: “Every true Christian must in some way be an Apostle. Although it is reserved for only a few to go to far off countries, yet Saint Therese of the Child Jesus teaches us to make our daily Christian life an apostolic offering for missions–an act highly meritorious and highly efficacious.”
