It followed that while many of the newcomers in the colonies were indifferent to religion, by far the larger number were not, and thought that, as they had been members of the English Established Church, they ought to be admitted into full membership in the churches of England's colonies. They felt, moreover, that the religious training of their children was being neglected because the New England churches ignored the child whose parents would not, or could not, submit to their terms of membership. Still more strongly did these people feel neglected and dissatisfied when, as the years went by, more and more of them were emigrants who had been acceptable members of the Puritan churches in England. They continued to be refused religious privileges because New England Congregationalism doubted the scriptural validity of letters of dismissal from churches where the discipline and church order varied from its own. Within the membership of the New England churches themselves, there was great uncertainty concerning several church privileges, as, for instance, how far infant baptism carried with it participation in church sacraments, and whether adults, baptized in infancy, who had failed to unite with the church by signing the Covenant, could have their children baptized into the church. Considerations of church-membership and baptism, for which the Cambridge Synod of 1648 was summoned, were destined, because of political events in England, to be thrust aside and to wait another eight years for their solution in that conference which framed the Half-Way Covenant as supplementary to the Cambridge Platform of faith and discipline. What has been termed the Anglo-colonial cause for summoning the Cambridge Synod finds explanation in the frequent questions and demands which English Independency put to the New England churches concerning church usage and discipline, and in the intense interest with which New England waited the outcome of the constitutional struggle in England between King and Parliament.
