The Protestant Church inculcated the law of individual fidelity to God, and declared that the highest obligation is that of personal faith and purity. What separated the Catholic and the Protestant was not merely a question of socialism as against individualism,[4] but it was also a problem of outward or inward law, of environment or intuition as the source of wholesome teaching, of ritualism or belief as the higher form of religious expression. The Protestants held that belief is better than ritual, faith than sacraments, inward authority than external force. They insisted that the individual has a right to think his own thoughts and to pray his own prayer, and that the revelation of the Supreme Good Will is to all who inwardly bear God's image and to every one whose will is a centre of new creative force in the world of conduct. They affirmed that the individual is of more worth than the social organism, the soul than the church, the motive than the conduct, the search for truth than the truth attained. These tendencies of Protestantism found expression in the rationalism that appeared in England at the time of the Commonwealth, and especially at the Restoration. All the men of broader temper proclaimed the use of reason in the discussion of theological problems. In their opinion the Bible was to be interpreted as other books are, while with regard to doctrines there must be compromise and latitude. We find such a theologian as Chillingworth recognizing "the free right of the individual reason to interpret the Bible."[5] To such men as Milton, Jeremy Taylor, and Locke the free spirit was essential, even though they had not become rationalists in the modern philosophical sense. They were slow to discard tradition, and they desired to establish the validity of the Bible; but they would not accept any authority until it had borne the test of as thorough an investigation as they could give it. The methods of rationalism were not yet understood, but the rational spirit had been accepted with a clear apprehension of its significance. [Sidenote: Toleration.]
