While a few philosophers, following after Plato, conjectured respecting the immortality of the soul, Christianity was the first religious system to teach eternal life as a fundamental doctrine. Coupled with this was the doctrine of the future judgment, at which man should give an account of his actions on this side of the grave. This was a new doctrine to the people of the world. The Christians introduced a new phase of social life by making their practice agree with their profession. It had been the fault of the moral sentiments of the ancient sages that they were never carried out in practice. Many fine precepts respecting right conduct had been uttered, but these were not realized by the great mass of humanity, and were put in practice by very few people. They had seldom been vitalized by humanizing use. Hence Christianity appeared in strong relief in the presence of the artificial system with which it came in contact. It had a faith and genuineness which were vigorous and refreshing. The Christians practised true benevolence, which was a great point in these latter days of selfishness and indifference. They systematically looked after their own poor and cared for the stranger at the gates. Later the church built hospitals and refuges and prepared for the care of all the oppressed. Thousands who were careworn, oppressed, or disgusted with the ways of the world turned instinctively to Christianity for relief, and were not disappointed. The Greeks and the Romans had never practised systematic charity until taught by the Christians. The Romans gave away large sums for political reasons, to appease the populace, but with no spirit of charity. But one of the most important of the teachings of the early church was to dignify labor. There was a new dignity lent to service. Prior to the dominion of the church, labor had become degrading, for slavery had supplanted free labor to such an extent that all labor appeared dishonorable. Another {273} potent cause of the demoralization of labor was the entrance of a large amount of products from the conquered nations. The introduction of these supplies, won by conquest, paralyzed home industries and developed a spirit of pauperism. The actions of the nobility intensified the evils. They spent their time in politics, and purchased the favor of the populace for the right of manipulating the wealth and power of the community. The Christians taught that labor was honorable, and they labored with their own hands, built monasteries, developed agriculture, and in many other ways taught that it is noble to labor.
