Evangelization

 "We wish to confirm once more that the task of evangelizing all people constitutes the essential mission of the Church." It is a task and mission which the vast and profound changes of present-day society make all the more urgent. Evangelizing is in fact the grace and vocation proper to the Church, her deepest identity. She exists in order to evangelize, that is to say, in order to preach and teach, to be the channel of the gift of grace, to reconcile sinners with God, and to perpetuate Christ's sacrifice in the Mass, which is the memorial of His death and glorious resurrection. -- Pope St. Paul VI, Evangelii Nuntiandi ("Evangelization in the Modern World")
