2019 marks the commemoration of a significant mission document of the Church—it is the 100th anniversary of Pope Benedict XV’s Maximum Illud, the first mission encyclical of the modern era. The Church also recalls that it is the 60th anniversary of St. John XXIII’s 1959 announcement of the Second Vatican Council, which gave us the mission decree Ad Gentes. The renewal of missionary evangelization continued with St. Paul VI’s Evangelii Nuntiandi (EN; 1975) and St. John Paul II’s Redemptoris Missio (RM; 1990), two documents that have had a pivotal effect on the “mission consciousness” of the contemporary Church. Finally, Pope Francis made another significant contribution in more recent times with his masterpiece Evangelii Gaudium, issued on November 24, 2013, the feast of Christ the King. – Author (first paragraph)
