In his encyclical Laudato Si’, Pope Francis calls us to transform our way of life in responding to the cry of the Earth and the cry of the poor. Illuminated by this call of the pope and the related article of the revised Constitutions, we, the friars of St. Maximilian M. Kolbe Province of South Korea, are extending our involvement in social issues to the area of creation care. (Of course, creation care is not a brand-new matter for us. More than ten years ago, when the then government pushed forward the ecologically controversial project called Four-Rivers Refurbishment Project, many friars joined social and ecclesial campaigns against it as well as praying and fasting-in-relay for the protection of the rivers.)
