From the sure and solid standing-point of Historical Christianity, believing Holy Scripture to be the Word of God, and the Christian Church to be the divinely-formed corporation for instructing, guiding, and illuminating mankind, remarkable examples of the Supernatural, miracles, spectral appearances of departed spirits, providential warnings by dreams and otherwise, the intervention and ministry of good angels, the assaults of bad, the certain power and efficacy of the gifts of Holy Church, the sanctity of consecrated places, and the persevering malignity of the devil and his legions, are gathered together, and set forth in the pages to follow. For it may reasonably be believed that, as Almighty God has graciously vouchsafed to intervene in the affairs of mankind in ages long past, so there has never been a period in which such merciful intervention has not from time to time taken place. Granted that in the days of Moses and Aaron, and of Elijah and Elisha, man owned miraculous powers, and wrought wonders by the gift of God; granted that in dreams and visions the will of the Most High was sometimes made known to favoured individuals of the Jewish Dispensation; remembering the miracles of our Lord’s apostles and disciples, and bearing in mind the divine and supernatural powers which were first entrusted to, and have been ever since exercised by, the Catholic Church, it is at once unreasonable and unphilosophical to deny the existence in the world of the supernatural and miraculous. As will be abundantly set forth, their presence and energy are in perfect accord and harmony with the universal experience of mankind. Sceptics may contemn and object, materialists may scoff; but numerous facts as well as a very general sentiment are against their conclusions and convictions. Floating straws show the direction and force of a current. As an example of the lengths to which an adoption of the materialistic principle will lead some persons, who regard themselves as “philosophers,” and as a specimen of the dangers which threaten us, it may be well to refer briefly to the proposal which has recently been formally and publicly made, viz., that in certain cases of hopeless disease or imbecile old age, physicians should be legally authorized to put an end to such patients by poison.
