In virtue of their baptism, all the members of the People of God have become missionary disciples (cf. Mt 28:19). All the baptized, whatever their position in the Church or their level of instruction in the faith, are agents of evangelization, and it would be insufficient to envisage a plan of evangelization to be carried out by professionals while the rest of the faithful would simply be passive recipients. The new evangelization calls for personal involvement on the part of each of the baptized. Every Christian is challenged, here and now, to be actively engaged in evangelization; indeed, anyone who has truly experienced God’s saving love does not need much time or lengthy training to go out and proclaim that love. Every Christian is a missionary to the extent that he or she has encountered the love of God in Christ Jesus: we no longer say that we are “disciples” and “missionaries”, but rather that we are always “missionary disciples”. If we are not convinced, let us look at those first disciples, who, immediately after encountering the gaze of Jesus, went forth to proclaim him joyfully: “We have found the Messiah!” (Jn 1:41). The Samaritan woman became a missionary immediately after speaking with Jesus and many Samaritans come to believe in him “because of the woman’s testimony” (Jn 4:39). So too, Saint Paul, after his encounter with Jesus Christ, “immediately proclaimed Jesus” (Acts 9:20; cf. 22:6-21). So what are we waiting for?I can add nothing to the Pope's remark except to say, Pope Paul VI insisted upon this more than forty years ago (Evangelii Nuntiandi); and every pope since then has repeated the call, especially Benedict XVI who announced the Holy Year of Faith.
Each year Saint Andrew leads us into Advent. After a single meeting with the Lord he told his brother, "We have found the Messiah!" There is no clearer, simpler explanation of what it means to be Catholic.
