Redemptoris Missio §22

²² All the Evangelists, when they describe the risen Christ's meeting with his apostles, conclude with the "missionary mandate": "All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations,...and lo, I am with you always, to the close of the age" (Mt 28:18-20; cf. Mk 16:15-18; Lk 24:46-49; Jn 20:21-23). This is a sending forth in the Spirit , as is clearly apparent in the Gospel of John: Christ sends his own into the world, just as the Father has sent him, and to this end he gives them the Spirit. Luke, for his part, closely links the witness the apostles are to give to Christ with the working of the Spirit, who will enable them to fulfill the mandate they have received.
