The sixteenth century! What a great era that was In comparison with the preceding centuries since Christianity was declared! From a religious and heroic point of view it was immeasurably a greater period than the nineteenth century, which has been marked chiefly for the triumphs of science, material progress, and social and political reforms. But in earnestness, in moral grandeur, and in discussions which pertain to the health and life of nations, the sixteenth century was greater than our own. Then began all sorts of inquiries about Nature and about mind, about revelation and Providence, about liberty of worship and freedom of thought; all of which were discussed with an enthusiasm and patience and boldness and originality to which our own times furnish no parallel. And united with this fresh and original agitation of great ideas was a heroism in action which no age of the world has equalled. Men risked their fortunes and their lives in defence of those principles which have made the enjoyment of them in our times the greatest blessing we possess. It was a new spirit that had arisen in our world to break the fetters which centuries of fraud and superstition and injustice had forged,--a spirit scornful of old authorities, yet not sceptical, with disgust of the past and hope for the future, penetrating even the hamlets of the poor, and kindling the enthusiasm of princes and nobles, producing learned men in every country of Europe, whose original investigations should put to the blush the commentators and compilers of this age of religious mediocrity and disguised infidelity. Such intellectual giants in the field of religious inquiry had not appeared since the Fathers of the Church combated the paganism of the Roman world, and will not probably appear again until the cycle of changes is completed in the domain of theological thought, and men are forced to meet the enemies of divine revelation marshalled in such overwhelming array that there will be a necessity for reformers, called out by a special Providence to fight battles,--as I regard Luther and Calvin and Knox. The great difference between the sixteenth and nineteenth centuries, outside of material aspects, is that the former recognized the majesty of God, and the latter the majesty of man. Both centuries believed in progress; but the sixteenth century traced this progress to first, and the nineteenth to second, causes. The sixteenth believed that human improvement was owing directly to special divine grace, and the nineteenth believes in the necessary development of mankind. The school of the sixteenth century was spiritual, that of the nineteenth is material; the former looked to heaven, the latter looks to earth. The sixteenth regarded this world as a mere preparation for the next, and the nineteenth looks upon this world as the future scene of indefinite and completed bliss. The sixteenth century attacked the ancient, the nineteenth attacks the eternal. The sixteenth destroyed, but
