Below in English is Pope Francis' letter announcing the “World Day of Prayer for the Care of Creation”
To my Venerable Brothers Cardinal Peter Kodwo Appiah TURKSON, President of the Pontifical Council for Justice and Peace Cardinal Kurt KOCH, President of the Pontifical Council for the Promotion of Christian Unity
The annual World Day of prayer for the Care of Creation offers to individual believers and to the community a precious opportunity to renew our personal participation in this vocation as custodians of creation, raising to God our thanks for the marvellous works that He has entrusted to our care, invoking his help for the protection of creation and his mercy for the sins committed against the world in which we live. The celebration of the Day on the same date as the Orthodox Church will be a valuable opportunity to bear witness to our growing communion with our orthodox brothers. We live in a time where all Christians are faced with identical and important challenges and we must give common replies to these in order to appear more credible and effective. Therefore it is my hope that this Day can involve, in some way, other Churches and ecclesial Communities and be celebrated in union with the initiatives that the World Council of Churches is promoting on this issue. Cardinal Turkson, as President of the Pontifical Council for Justice and Peace, I asking you to inform the Justice and Peace Commissions of the Bishops’ Conferences, as well as the national and international Organizations involved in environmental issues about the establishment of the World Day of Prayer for the Care of Creation, so that in union with the needs and the local situation , this celebration can be rightly marked with the participation of the entire People of God: priests, men and women religious and the lay faithful. For this reason, it will be the task of this Dicastery, in collaboration with the Episcopal Conferences to set up relevant initiatives to promote and illustrate this Day, so that this annual celebration becomes a powerful moment of prayer, reflection, conversion and the adoption of appropriate life styles.
Cardinal Koch, as President of the Pontifical Council for the Promotion of Christian Unity, I’m asking you to make the necessary contacts with the Ecumenical Patriarchate and with the other ecumenical organisations so that this World Day can become the sign of a path along all believers in Christ walk together. It will also be your Dicastery’s task to take care of the coordination with similar initiatives set up by the World Council of Churches. Whilst I look forward to the widest possible cooperation for the best start and development of the World Day of Prayer for the Care of Creation, I invoke the intercession of Mary, the Mother of God and of St. Francis of Assisi, whose Canticle of the Creatures inspires so many men and women of goodwill to live in praise of the Creator and with respect for creation. I support this pledge along with my Apostolic Blessing which I impart with all my heart to you, my dear Cardinals, and to all those who collaborate in your ministry. From the Vatican, 6th August 2015 Feast of the Transfiguration of the Lord.
