The octave of prayer was first observed by the Franciscan Friars and Sisters of Atonement in New York in 1908. It has since grown to be observed worldwide. In this annual observance, Christians work toward Christ’s prayer at the Last Supper “that all may be one” (John 17:21).
The prayers and theme are developed by an international effort of ecumenical partners. This year’s theme is “Abide in my love and you shall bear much fruit” (Cf. John 15:1-17). Among the many collaborators are the World Council of Churches (WCC) and its Commission on Faith and Order and The Pontifical Council for Promoting Christian Unity.
