When… the time approached for the effulgent beauty of Muhammad to dawn upon the world, the control of Christian affairs passed into the hands of ignorant priests. Those heavenly breezes, soft-flowing from the regions of Divine grace, died away, and the laws of the great Evangel, the rock-foundation on which the civilization of the world was based, turned barren of results, this out of misuse and because of the conduct of persons who, seemingly fair, were yet inwardly foul.

The noted historians of Europe, in describing the conditions, manners, politics, learning and culture, in all their aspects, of early, medieval and modern times, unanimously record that during the ten centuries constituting the Middle Ages, from the beginning of the sixth century of the Christian era till the close of the fifteenth, Europe was in every respect and to an extreme degree, barbaric and dark. The principal cause of this was that the monks, referred to by European peoples as spiritual and religious leaders, had given up the abiding glory that comes from obedience to the sacred commandments and heavenly teachings of the Gospel, and had joined forces with the presumptuous and tyrannical rulers of the temporal governments of those times. They had turned their eyes away from everlasting glory, and were devoting all their efforts to the furtherance of their mutual worldly interests and passing and perishable advantages. Ultimately things reached a point where the masses were hopeless prisoners in the hands of these two groups, and all this brought down in ruins the whole structure of the religion, culture, welfare and civilization of the peoples of Europe.
