A breakthrough in mission theology for the modern world and the Church, this encyclical introduces the commitment to evangelization as the Church's primary service. This introduction is followed by seven sections which cover: the connection between Christ the evangelizer and a Church which, by Christ's mandate, is evangelizing by definition; the content of evangelization in all its breadth; the methods of evangelization; the beneficiaries of evangelization; those who carry out the ministry of evangelization; the spirit of evangelization; and Mary as the Star of Evangelization.
