There is probably no other form of organized group life in the Canadian community which has been more unstable than the organization of religion. The history of Protestantism in the country is very largely a history of church unions and sectarian divisions. If account were taken of the activities of the Jesuit Order in New France, of the defection at various times of many Catholics to Protestant religious sects, and of recent anti-clerical movements in the province of Quebec and among the Catholic immigrant population in Western Canada, the same would be found to be true in a general way of Catholic development in the country.
The dream of the universal church, of the church which would unite all nations and all classes, has never been fully realized, in Canada as elsewhere in the Western World. Efforts to accomplish such an object, by the establishment of a state church, by the union of separate religious bodies, or by the initiation of a new religious movement which would transcend all other religious groups have invariably failed in face of the expression of strong separatist forces in religious organization. Out of every such effort to create an all-embracing religious body in the community have come new movements of religious protest, the religious sect.
On the other hand, the sect form of religious organization has proved equally unstable. The pure sect, the religious group organized exclusively in terms of the other-worldly or spiritual interests of its members, has never been more than an idealistic conception of religious organization finding expression in movements of religious reform at various times. The necessity of existing in a worldly society has led religious sects from the very beginning to accept to some extent a worldly outlook. Where they have not succeeded in developing into churches, or at any rate into types of religious organization accommodated to the secular community, they have perished. Almost from the moment of their inception, they have been forced to make such a choice between social accommodation or extinction.
