The English Society of the Grail is a secular institute, autonomous and ecclesiastically approved, with its own rules and constitution. Its members are not religious, but laywomen who wish to dedicate their whole lives to work for Christ in the lay apostolate. Those who come to the Society come to an adventurous family.

Any girl can join the Society if she is willing to give herself to Christ to do anything, anywhere and at any time. There is room Hi die Society for girls of every social level and of every occupation, for anyone who wants to tlirow in her lot for life with a society of pioneers and who is prepared to accept die discipline of that Society. For lay institutes must be disciplined and their members be bound together with bonds of steel.

The lay apostolate cannot be driven by any mere transitory enthusiasm—indeed there is a distinct danger for women in any violent and undisciplined enthusiasm and if this is the driving power of an organisation then the life of an apostle cannot last longer than a few years.
