e) in academic halls of residence there is very much to recommend good relations between Catholics and other Christian students. With suitable guidance, they can learn, through these relations, to live together in a deeper ecumenical spirit and be faithful witnesses of their Christian faith;
f) it is important to give emphasis to prayer for unity, not only during the Week of Prayer for this purpose but also at other times during the year. Depending on circumstances of place and persons, and in conformity with the existing rules about shared worship joint retreats under the guidance of a spiritual master, may also be envisaged;
g) there is a wide field of common witness in social or welfare works. Students should be trained and encouraged in this-not only theology students, but also those of other faculties, such as law, sociology and political science. By their contribution these students will help to promote and realize such initiatives;
h) chaplains, student counselors and professors will have a particular concern to carry out their tasks in an ecumenical spirit, especially by organizing some of the initiatives indicated above. This obligation demands from them a deep knowledge of the doctrine of the Church, an adequate competence in academic subjects, unfailing prudence and a balanced attitude: all these qualities should enable them to help their students to harmonize their own life of faith with openness to others.
