The most recent pronouncement of the Holy See on the Ecumenical Movement is the Instruction of the Holy Office to Local Ordinaries of December 20, 1949. By its provisions Catholic ecumenical work, described in it as ‘reunion’ work, is safeguarded by cautionary measures and put under the direct supervision of the bishops, who are urged to give it prudent encouragement and direction, as a work which ‘should daily assume a more significant place within the Church’s pastoral care’. They are to appoint suitable priests, in each diocese, to make a special study of the movement and everything connected with it.
If any priest is contemplating the task laid upon him as a result of this directive, he cannot do better than make A History of the Ecumenical Movement the basis and starting point of his studies; a massively conceived and well planned volume of some eight hundred pages, written by fifteen experts in their respective subjects. Hardly an idea, event or person of ecumenical importance lacks at least a reference in these pages, and the full bibliography will give sufficient aid in following out a more complete study.
The volume falls into two distinct parts. The first comprises a history, from the Reformation onwards, of efforts by ecumenically minded persons to bring about the healing of schisms within Christendom. The second deals with the Ecumenical Movement proper; an organized movement expressing itself in World Conferences and culminating in the formation of the World Council of Churches at Amsterdam in 1948.
