Saint Barnabas, apostle - Memorial
"Without cost you have received; without cost you are to give"
Now, the Lord Jesus, before freely giving His life for the world, so arranged the Apostles' ministry and promise to send the Holy Spirit that both they and the Spirit might be associated in effecting the work of salvation always and everywhere. Throughout all ages, the Holy Spirit makes the entire Church one in communion and in ministering...
From the very beginning, the Lord Jesus "called to Himself those whom He wished; and He caused twelve of them to be with Him, and to be sent out preaching (Mk 3,13). Thus the Apostles were the first budding-forth of the New Israel, and at the same time the beginning of the sacred hierarchy. Then, when He had by His death and His resurrection completed once for all in Himself the mysteries of our salvation and the renewal of all things, the Lord, having now received all power in heaven and on earth (Mt 28,18), before He was taken up into heaven, founded His Church as the sacrament of salvation and sent His Apostles into all the world just as He Himself had been sent by His Father (Jn 20,21), commanding them: "Go, therefore, and make disciples of a 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" (Mt 28,19f.).
Whence the duty that lies on the Church of spreading the faith and the salvation of Christ, not only in virtue of the express command which was inherited from the Apostles by the order of bishops, assisted by the priests, together with the successor of Peter and supreme shepherd of the Church, but also in virtue of that life which flows from Christ into His members... The mission of the Church, therefore, is fulfilled by that activity which makes her, obeying the command of Christ and influenced by the grace and love of the Holy Spirit, fully present to all people and nations, in order that, by the example of her life and by her preaching, by the sacraments and other means of grace, she may lead them to the faith, the freedom and the peace of Christ; that thus there may lie open before them a firm and free road to full participation in the mystery of Christ.
