Evangelii gaudium (The Joy of the Gospel) is a 2013 apostolic exhortation by Pope Francis "On the proclamation of the Gospel in today's world". In its opening paragraph, Pope Francis urged the entire Church "to embark on a new chapter of evangelism". According to the exhortation, the Church must understand itself as a community of missionary disciples, who are "permanently in a state of mission".
