Catholic leaders at an international mission conference for the Americas said the church must become a missionary community with a new mentality. The Third American Missionary Congress drew more than 2,000 laypeople, bishops, priests and religious to Quito, Ecuador, Aug. 12-17 to discuss challenges for mission, from family life and fundamentalism to ecology and science. The closing Mass marked the official launch of the "great continental mission" that bishops from Latin America and the Caribbean announced in May 2007 during their fifth general conference in Aparecida, Brazil. That mission must build on "a spirit that was begun in Aparecida, the spirit of mission, of discipleship," said Auxiliary Bishop Octavio Cisneros of Brooklyn, N.Y.
