The attentive student of the mythology of the nations of antiquity cannot fail to discover many vestiges of a primitive revelation of some of the principal truths of religion, although in the lapse of time they have been so distorted and mingled with fiction that it requires careful study to sift the few remaining grains of truth from the great mass of superstition and error in which they are all but lost. Among these truths may be reckoned monotheism, or the belief in, and the worship of, one only God, which the learned Jesuit, the Rev. Aug. Thebaud, in his "Gentilism," has proved to have been the primitive belief of all nations. It may not, however, be so generally known that the doctrine of Purgatory, or a future state of purification, was also held and taught in all the religious systems in the beginning. While a knowledge of this fact cannot add anything to the grounds of our faith as Catholics, it will not be wholly without interest, and it will, besides, better enable us to give a reason for the faith that is in us. It was left to Martin Luther to found an ephemeral religious system that should deny this dogma, founded no less on revelation than on right reason; but, then, logic has never been one of the strong points of Protestants. Before turning my attention to the nations of the pagan world, I shall briefly give the Jewish belief on this point. It may not generally be known that the doctrine of a middle state is not explicitly proposed to the belief of the Jews in any of the writings of the Old Testament, although it was firmly held by the people. We depend for our knowledge of this fact mainly on the celebrated passage of the Second Book of Machabees (xii. 43-46). The occasion on which the doctrine was stated was this: Some of the soldiers of Judas Machabeus, the leader of the Jewish armies, fell in a certain battle; and when their fellow-soldiers came to bury them, they discovered secreted in the folds of their garments some parts of the spoils of one of the pagan shrines, which it was not permitted them to keep. After praying devoutly, the sacred writer goes on to say that Judas, "Making a gathering, sent twelve thousand drachms of silver to Jerusalem for sacrifices to be offered for the sins of the dead, thinking well and religiously concerning the resurrection [for if he had not hoped that they who were slain should rise again, it would have seemed superfluous and vain to pray for the dead]. And because he considered that they who had fallen asleep with godliness had great grace laid up for them. It is, therefore, a holy and wholesome thought to pray for the dead, that they may be loosed from sins."
