1) In case we believe the sacrifice to this evil god has ceased, Fr. Euteneuer, president of Human Life International, in this article from New Oxford Review, reminds us it has not.
“Those who are uncomfortable with the thought and talk of demons have a decision to make: Remain in the dark and ignore a basic teaching of the Church regarding spiritual warfare or open your eyes and join the rest of us in the fight against the demons who are working evil in our midst. One such wicked work is the dirty business of abortion. No human activity glorifies Satan and his minions more than abortion.
“Abortion is fundamentally a business — a business based on a perverse concept of human rights. Abortion is a commodity cleverly marketed to women under the ideological rubric of "free choice" that draws in huge profits from the deaths of innocents. The abortion industry is a profit-driven, raw killing machine. The enormous amount of cash it generates is the "lifeblood" that perpetuates its existence.
“The spiritual dimension of this grisly business, however, is its systematizing of ritual blood sacrifice to the god of child murder who, in the Old Testament, is called Moloch. This demon of child sacrifice appears in many forms and cultures throughout history — Phoenician, Carthaginian, Canaanite, Celtic, Indian, Aztec, and others — but it is always the same bloodthirsty beast that demands the killing of children as a form of worship. This demon seeks public endorsement and ever new expressions of killing to increase its "worship." In some of the ancient forms of these evil practices, huge drums were beaten beside the places of sacrifice as the rituals proceeded. These drums were used to drown out the screams of the victims who were being sacrificed on the altars.”
2) Moloch, as worshipped in Carthage, was built of metal, hollowed out to allow fire to heat his outstretched hands upon which were cast the children of Carthage in a sacrifice dramatized by Flaubert in his historical novel Salammbo:
“The brazen arms were working more quickly. They paused no longer. Every time that a child was placed in them the priests of Moloch spread out their hands upon him to burden him with the crimes of the people, vociferating: "They are not men but oxen!" and the multitude round about repeated: "Oxen! oxen!" The devout exclaimed: "Lord! eat!" and the priests of Proserpine, complying through terror with the needs of Carthage, muttered the Eleusinian formula: "Pour out rain! bring forth!"
“The victims, when scarcely at the edge of the opening, disappeared like a drop of water on a red-hot plate, and white smoke rose amid the great scarlet colour.
“Nevertheless, the appetite of the god was not appeased. He ever wished for more. In order to furnish him with a larger supply, the victims were piled up on his hands with a big chain above them which kept them in their place. Some devout persons had at the beginning wished to count them, to see whether their number corresponded with the days of the solar year; but others were brought, and it was impossible to distinguish them in the giddy motion of the horrible arms. This lasted for a long, indefinite time until the evening. Then the partitions inside assumed a darker glow, and burning flesh could be seen. Some even believed that they could descry hair, limbs, and whole bodies.” (Chapter XIII)
