The League issues a Leaflet, aimed to assist clergy and lay people offering intercessions, biddings and the prayer of the faithful at the Mass and the Divine Office, especially Vespers, on each day in the Week of Prayer for Christian Unity.
There is also a Litany and Collect that can be used in prayer groups and at ecumenical services.
The scheme for the daily prayers is based on the format used by Fr Paul Couturier from the 1930s onwards, but adapted to take account of the different traditions in the Church in Britain in the twenty-first century. They are modelled on the Solemn Prayers at the Good Friday Liturgy, at which are also remembered not just those of one's own Church, but all those who believe in Christ, those who do not believe in Christ but who do have faith in God, as well as those who do not believe in God - towards the unity of all humanity in the charity and truth of Christ, "according to his will, according to his means".
The Leaflet can be downloaded here, or a hard copy can be ordered from the Priest Director of the Apostleship of Prayer, Fr Chris Stephenson, by email here, or can be picked up from St Paul's Bookshop by Westminster Cathedral in person.
