“A man, or rather a monster, Half man and half fish, coming from the sea, appeared near Babylon; he had two heads; one, which was the highest, resembled that of man, the other that of a fish. He had the feet of a man, and the tail of a fish; and his speech and voice resembled that of a man: a representation of him is still preserved. This monster dwelt by day with men, but took no food; he gave them knowledge of letters, arts, and sciences; he taught them to build towers and temples; and to establish laws; he instructed them in the principles of geometry; taught them to sow, and to gather the fruits of the earth; in short, whatever could contribute to polish and civilize their manners. At sun set he retired to the sea, in which he passed the night. There appeared likewise others of the same species.”
It is an interesting secret, which emerges from the careful study of Catholic doctrine, as it has been articulated through the centuries. If we want to understand the Devil, that is the first place to look. The Church is the expert on demonic activity, having been in active competition with the infernal powers all this time. She is kept on her toes as their principal target. Until recently, she spoke with one clear voice, the words of Our Saviour, and indeed, were it not for divine assistance she would have succumbed to the satanic service, long long ago.
