A Reviewer in the August number of Theology has written that ‘Rome’s tragic rejection of the Ecumenical Movement is one of the challenges of our day, and it has yet to be faced and met’. By its context, a review of Salmon’s Infallibility of the Church, this rather cryptic sentence seems to imply that the nature of the Church (as Catholics conceive it) makes Catholicism essentially incapable of absorbing the spirit of Ecumenism. If that were actually the case it would be truer to say that Ecumenism rejects Rome, not that Rome has rejected the Ecumenical Movement.

In order to test the validity of this judgment it is necessary to define what constitutes the essential spirit of Ecumenism, and what are the aims to which it gives birth. But it is precisely here that a difficulty lies, because the Ecumenical Movement has been fluid in its development, originating in a spontaneous desire for Christian unity, due partly to the threat of world war during the first decade of the century, and partly to the problems set to missionary effort by divisions among Christians. The double source of the desire for unity resulted in the emergence of two tendencies within the growing movement. In one, emphasis was laid upon co-operation between Christian bodies, in spite of differences of doctrine.
