From Luther’s exposition of the fourth commandment in his Treatise on Good Works (1520), alluding to King Manasseh’s actions in II Kings 21:
What else is it but to sacrifice one’s own child to an idol and burn it when parents train their children more in the love of the world than in the love of God, and let their children go their own way and get burned up in worldly pleasure, love, enjoyment, lust, goods, and honor, but let God’s love and honor and the love of eternal blessings be extinguished in them? (LW 44:83)
