Focolare, Community of Sant'Egidio, Neocatechumenal Way, Legionaries of Christ, Communion and Liberation, Opus Dei. These are but a few of the most recognizable names in the broader context of the so-called ecclesial movements. Their history goes back to the period following the First Vatican Council, crosses Vatican II, and develops throughout the twentieth century. It is a history that prepares the movements' rise in the last three decades, from John Paul II to Francis. These movements are a complex phenomenon that shapes the Church now more than before, and they play a key role for the future of Catholicism as a global community, in transition from a Europe-centered tradition to a world Church.
