Christ who commanded prayer for the labourers in the harvest, has also personally called those labourers. The words of his call are preserved in the treasure of the Gospel: ” Follow me, and I will make you fishers of men” (Mt 4:19). “Come, follow me” (Mt 19:21). “If anyone serves me, he must follow me” (Jn 12:26). The words of his call are entrusted to our apostolic ministry and we must make them heard, like the other words of the Gospel, “to the ends of the earth” (Acts 1:8). It is Christ’s will that we would make them heard. The People of God have a right to hear them from us.
