Ten years ago the Latin American Catholic Bishops held their Second General Conference in Medellín, Colombia. The conference had a great influence not only within the Catholic Church, but also on the formation of socioeconomic and political issues in Latin American countries. At the time of this writing, we are in the midst of preparations for the Third General Conference taking place in Puebla, Mexico, in October 1978. Therefore, this seems a good opportunity to reflect on the general processes of change in the Church leading to Puebla and their implications for the future.
