This, they said, was absolute Erastianism, or subjection of the church of God to the regulations of an earthly government, and therefore but one degree better than prelacy or popery .-- Again, the more moderate party were content to allow the king's title to the throne, and in secular affairs to acknowledge his authority, so long as it was exercised with due regard to the liberties of the subject, and in conformity to the laws of the realm.
