Book excerpt: To be Christians means to be missionaries, to be apostles. It is not enough to discover Christ you must bring him to others! John Paul II, Fourth World Youth Day. Pope John Paul II urged the church repeatedly and persistently to proclaim the gospel to all humanity. This summons to a new evangelization characterized his papacy. But what does the new evangelization mean? And who is supposed to evangelize? What is the role of the parish? Of married couples? How do we evangelize teens? And what are the ecumenical dimensions of evangelism? In this book twenty-two authors address these and many other issues. Cardinal Avery Dulles describes the evangelical shift in the church since Vatican II; those involved in day-to-day evangelism provide practical tips for evangelizing the poor (Sr. Linda Koontz), street evangelism (Leonard Sullivan), using spiritual gifts (Peter Herbeck) and much more.
