Thus was born the second great idea of the Reformation,--the _supreme authority of the Scriptures_, to which Protestants of every denomination have since professed to cling. They may differ in the interpretation of texts,--and thus sects and parties gradually arose, who quarrelled about their meaning,--but none of them deny their supreme authority. All the issues of Protestants have been on the meaning of texts, on the interpretation of the Scriptures,--to be settled by learning and reason. It was not until rationalism arose, and rejected plain and obvious declarations of Scripture, as inconsistent with reason, as interpolations, as uninspired, that the authority of the Scriptures was weakened; and these rationalists--and the land of Luther became full of them--have gone infinitely beyond the Catholics in undermining the Bible. The Catholics never have taken such bold ground as the rationalists respecting the Scriptures. The Catholic Church still accepts the Bible, but explains away the meaning of many of its doctrines; the rationalists would sweep away its divine authority, extinguish faith, and leave the world in night. Satan came into the theological school of the Protestants, disguised in the robes of learned doctors searching for truth, and took away the props of religious faith. This was worse than baptizing repentance with the name of penance. Better have irrational fears of hell than no fears at all, for this latter is Paganism. Pagan culture and Pagan philosophy could not keep society together in the old Roman world; but Mediaeval appeals to the fears of men did keep them from crimes and force upon them virtues.
