Evangelii Gaudium §183

183. Consequently, no one can demand that religion should be relegated to the inner sanctum of personal life, without influence on societal and national life, without concern for the soundness of civil institutions, without a right to offer an opinion on events affecting society. Who would claim to lock up in a church and silence the message of Saint Francis of Assisi or Blessed Teresa of Calcutta? They themselves would have found this unacceptable. An authentic faith – which is never comfortable or completely personal – always involves a deep desire to change the world, to transmit values, to leave this earth somehow better that we found it. We love this magnificent planet on which God has put us, and we love the human family which dwells here, with all its tragedies and struggles, its hopes and aspirations, its strengths and weaknesses. The earth is our common home and all of us are brothers and sisters. If indeed “the just ordering of society and of the state is a central responsibility of politics”, the Church “cannot and must not remain on the sidelines in the fight for justice”.[150] All Christians, their pastors included, are called to show concern for the building of a better world. This is essential, for the Church’s social thought is primarily positive: it offers proposals, it works for change and in this sense it constantly points to the hope born of the loving heart of Jesus Christ. At the same time, it unites “its own commitment to that made in the social field by other Churches and Ecclesial Communities, whether at the level of doctrinal reflection or at the practical level”.[151]
