English political thought from 1528 to 1558 was dominated by the question of obedience to civil authority. English Lutherans stressed the duty of obedience to the prince as the norm; however, if he commands that which is immoral one should passively disobey. The defenders of Henrician royal supremacy, while attempting to strengthen the power of the crown, used similar arguments to stress unquestioned obedience to the king. During Edward VI's reign this teaching of obedience was popularized from the pulpit. However, with the accession of Mary a new view regarding obedience gained prominence. Several important Marian exiles contended that the principle that God is to be obeyed rather than man entails the duty of Christians to resist idolatrous and evil rulers for the sake of the true Protestant religion.
