It is necessary to start with a definition of terms which are often confounded in their use. “Puritans,” “Separatists,” and “Nonconformists” might in fact be terms equally applicable to many individuals, but none the less they were distinctive, and in many cases indicated very broad divergencies and characteristics in opinion, belief, and conduct. Nonconformists and Separatists were alike Puritans,—the latter intensively such. Puritanism developed alike into Nonconformity and Separatism. The earliest Puritans came to be Nonconformists, after trying in vain to retain a ministry and communion in the English Church as established by royal and civil authority, and after being driven from it because of their persistent demands for further reform in it. As heartily as did those who remained in its communion, they believed in the fitness of an established nationalized Church. They wished to be members of such a Church themselves; and not only so, but also to force upon others such membership. It was not to destroy, but to purify; not to deny to the civil authority a legislative and disciplinary power in religious matters, but to limit the exercise of that right within Scriptural rules and methods. They had sympathized in the processes of reform so far as these had advanced, but complained that the work had been arbitrarily arrested, was incomplete, was inconsistently pursued, was insecure in the stage which it had reached, and so left without the warrant which Scripture alone could furnish as a substitute for repudiated Rome.
