But, on the other hand, the extreme consequences are obvious, and it is enough that the "will" of man should agree to gather them in charitably and without repugnance in order to obtain salvation. St. Matthew says that at the Last Judgment those who are lost will be separated from those who are saved, and that the King will call the latter to his right hand, saying, "Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world. For I was an-hungered, and ye gave me meat: I was thirsty and ye gave me drink ... I was naked and ye clothed me.... I was in prison, and ye came unto me." "And when," replied the just, "saw we thee, O Lord, an-hungered or thirsty or naked? When saw we thee sick or in prison and came unto thee?" and the King shall answer and say unto them, "Inasmuch as ye have done it unto the least of these my brethren, ye have done it unto me." Then shall he say also unto them on the left hand, "Depart from me, ye cursed, into everlasting fire ... for I was an-hungered, and ye gave me no meat: I was thirsty, and ye gave me no drink ... sick and in prison and ye visited me not." Then shall they answer him, saying, "When saw we thee an-hungered, or a-thirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee?" Then shall he answer them, saying, "Inasmuch as ye did it not to one of the least of these, ye did it not to me." This is the fundamental difference between heathen and Christian morality; between intellectual Greek philosophy and practical modern science; between the aesthetic ideal and the ideal of "life." * * * * * Positive science, therefore, has made us realize a part of Christianity. We might almost say that the monastic orders practically represented, throughout the centuries and the different civilizations, the only form of life which is really life--that which science has revealed to-day.
