[Sidenote: Other-worldliness of mediæval Christianity.] Christianity opposed this view of life with an entirely different one. It laid persistent emphasis upon man's existence after death, which it declared infinitely more important than his brief sojourn in the body. Under the influence of the Church this conception of life had gradually supplanted the pagan one in the Roman world, and it was taught to the barbarians. The other-worldliness became so intense that thousands gave up their ordinary occupations and pleasures altogether, and devoted their entire attention to preparation for the next life. They shut themselves in lonely cells; and, not satisfied with giving up most of their natural pleasures, they inflicted bodily suffering upon themselves by hunger, cold, and stripes. They trusted that in this way they might avoid some of the sins into which they were prone to fall, and that, by self-inflicted punishment in this world, they might perchance escape some of that reserved for them in the next. As most of the writers and teachers of the Middle Ages belonged to this class of what may be called professional Christians, i.e., the monks, it was natural that their kind of life should have been regarded, even by those who continued to live in the world, as the ideal one for the earnest Christian. [Sidenote: The Church the one agent of salvation.] The barbarians were taught that their fate in the next world depended largely upon the Church. Its ministers never wearied of presenting the momentous alternative which faced every man so soon as this fleeting earthly existence should be over,--the alternative between eternal bliss and perpetual, unspeakable physical torment. Only those who had been duly baptized could hope to reach heaven; but baptism washed away only past sins and did not prevent constant relapse into new ones. These, unless their guilt was removed through the instrumentality of the Church, would surely drag the soul down to perdition. [Sidenote: Miracles a source of the Church's power.] The divine power of the Church was, furthermore, established in the eyes of the people by the miraculous works which her saints were constantly performing. They healed the sick and succored those in distress. They struck down with speedy and signal disaster those who opposed the Church or treated her holy rites with contempt. To the reader of to-day the frequency of the miracles recorded in mediæval writings seems astonishing. The chronicles and biographies are filled with accounts of them, and no one appears to have doubted their common occurrence.[26] [Sidenote: The Church and the Roman government.]
