Boden, in his Demonology,[398] cites more than one instance of demons who have requested prayers, and have even placed themselves in the posture of persons praying over a grave, to point out that the dead persons wanted prayers. Sometimes it will be the demon in the shape of a wretch dead in crime, who will come and ask for masses, to show that his soul is in purgatory, and has need of prayers, although it may be certain that he finally died impenitent, and that prayers are useless for his salvation. All this is only a stratagem of a demon, who seeks to inspire the wicked with foolish and dangerous confidence in their being saved, notwithstanding their criminal life and their impenitence; and that they can obtain salvation by means of a few prayers, and a few alms, which shall be made after their death; not regarding that these good works can be useful only to those who died in a state of grace, although stained by some venial fault, since the Scripture informs us[399] that nothing impure will enter the kingdom of heaven. It is believed that the reprobate can sometimes return to earth by permission, as persons dead in idolatry, and consequently in sin, and excluded from the kingdom of God, have been seen to come to life again, be converted, and receive baptism. St. Martin was as yet only the simple abbot of his monastery of Liguge,[400] when, in his absence, a catechumen who had placed himself under his discipline to be instructed in the truths of the Christian religion died without having been baptized. He had been three days deceased when the saint arrived. He sent everybody away, prayed over the dead man, resuscitated him, and administered to him the baptismal rite. This catechumen related that he had been led before the tribunal of the Supreme Judge, who had condemned him to descend into the darkness with an infinity of other persons condemned like himself; but that two angels having represented to the Judge that it was this man for whom St. Martin interceded, God commanded the two angels to bring him back to earth, and restore him to Martin. This is an instance which proves what I have just said, that the reprobate can return to life, do penance, and receive baptism. But as to what some have affirmed of the salvation of Falconila, procured by St. Thecla, of that of Trajan, saved by the prayers of St. Gregory, pope, and of some others who died heathens, this is all entirely contrary to the faith of the church and to the holy Scripture, which teach us that without faith it is impossible to please God, and that he who believes not and has not received baptism is already judged and condemned. Thus the opinions of those who accord salvation to Plato, Aristotle, Seneca, &c., because it may appear to them that they lived in a praiseworthy manner, according to the rules of a merely human and philosophical morality, must be considered as rash, erroneous, false, and dangerous.
