Yes, in ancient times, certain pagan cultures did practice child sacrifice as part of their religious rituals to gods such as Baal. The Bible speaks against such practices vehemently, highlighting them as abominations in the sight of God. For instance, in the context of the practices of the Canaanites, God warned the Israelites against imitating their horrific customs, including child sacrifice.

Jeremiah 19:5 says, “They have built the high places of Baal to burn their children in the fire as offerings to Baal—something I did not command or mention, nor did it enter my mind.”

This passage, among others, reflects God’s condemnation of such acts, emphasizing that they are contrary to His will and nature. The Bible portrays God as a protector of the innocent and vulnerable, including children, and commands His followers to care for and protect them.
