In this work of physical regeneration three centuries were again spent. But at the close of this first period, it was seen, on a sudden, how little the olden spirit of dissension had been really conquered, or even mollified. The faith, it was said, may, in all essential points, be perfectly identical, but a division may be, and still subsists, notwithstanding. But what does that mean, but that the God and Savior of the world worshiped by the East, is different from Him whom the West acknowledges? And thus the one God and the one faith was in the life of man again divided into two; and this singular schism, without any adequate cause, still subsists to the present day.[40] In the following great period a fresh life blossomed in rich and manifold expansion out of that revelation of love which, properly speaking, now first of all put forth its full vital energies, giving a new shape to all the institutions of human society, and impressing on art, as well as on moral and political science, a new character, totally different from that which they possessed among the most enlightened nations of antiquity. Viewed in its loving aspect, _i.e._, in its chivalry, there is much in this period to attract and engage our enthusiasm and sympathies, but for the fearful discord which broke out within it, and set one half of the world in hostile array against the other. The two powers which ought to work together for one divine end--the two swords of which the Lord had said, “It is enough,”[41]--the spiritual sword of the kingdom of faith and truth, and the civil sword of earthly justice, were drawn and held in threatening attitude against each other, by which, however, the minds of men were torn and distracted by the inward struggle of conflicting duties in a far greater degree than the external peace of society was disturbed. But it was not merely in such a collision that the strife alone showed itself; but it extended even to the confusion of the two domains, and a forgetfulness of their proper duties and respective positions. In the instance, it is true, of the mailed ecclesiastic, however, at first sight, the union in one person of such opposite characters as the soldier and priest may startle the mind, the gallant and noble bearing of the spiritual knight soon reconciles us to the strange phenomenon. So, too, when he whose vocation it was to hold the pastoral staff began also to sway the scepter of a civil prince, the eminent skill and judgment with which the difficult task of discharging the double and often conflicting duties of so mixed a sovereignty was accomplished, silence every murmur of a protest. But when he who ought to carry the crosier of peace hoisted the pennon of war, such a sight naturally gave great offense, and sadly perplexed the minds of men.
