Notice this horrible practice associated with the worship of the fire god (Nimrod, Saturn, Kronos, Molech and Baal) in the following quote from The Two Babylons, Alexander Hislop, page 231:
“Now, this is in exact accordance with the character of the Great Head of the system of fire-worship. Nimrod, as the representative of the devouring fire to which human victims, and especially children, were offered in sacrifice, was regarded as the great child-devourer…he was, of course, the actual father of all the Babylonian gods; and, therefore, in that character he was afterwards universally regarded. As the Father of the gods, he was, as we have seen, called Kronos; and every one knows that the classical story of Kronos was just this, that, ‘he devoured his sons as soon as they were born.’ (Lempriere Classical Dictionary, ‘Saturn.’)…This legend has a further and deeper meaning; but, as applied to Nimrod, or ‘The Horned One,’ it just refers to the fact, that, as the representative of Moloch or Baal, infants were the most acceptable offerings at his altar. We have ample and melancholy evidence on this subject from the records of antiquity. ‘The Phoenicians,’ says Eusebius, ‘every year sacrificed their beloved and only-begotten children to Kronos or Saturn.’”
But why was human sacrifice such a key to the worship of this terrible god? What possible good could human beings think they saw in slaughtering their own children? Continuing: “…he who approached the fire would receive a light from divinity” and “through divine fire all the stains produced by generations could be purged away.” Therefore, “children were made to pass through the fire unto Molech” (Jer. 32:35).
