Iconoclasm in the biblical sense is the destruction of idols and images used in the worship of God or false gods. The Second Commandment is explicitly iconoclastic: "You shall not make for yourself a carved image, or any likeness of anything... You shall not bow down to them or serve them" (Exodus 20:4-5). The godly kings of Israel were praised for iconoclastic reforms: Hezekiah "removed the high places and broke the pillars and cut down the Asherah. And he broke in pieces the bronze serpent that Moses had made" (2 Kings 18:4). Even a legitimate symbol (the bronze serpent) became an idol when people burned incense to it, and Hezekiah rightly destroyed it. Josiah's reformation was likewise iconoclastic, tearing down the high places and altars of Baal (2 Kings 23:4-14).
The act or practice of breaking images or idols; the destruction of images set up for worship.
ICONOCLASM, n. The breaking or destruction of images. Webster treated iconoclasm as a straightforward term for the destruction of religious images, without the negative connotation it later acquired in secular usage.
• Exodus 20:4-5 — "You shall not make for yourself a carved image, or any likeness of anything that is in heaven above..."
• 2 Kings 18:4 — "He removed the high places and broke the pillars and cut down the Asherah."
• 2 Kings 23:4-6 — "The king commanded... to bring out of the temple of the LORD all the vessels made for Baal... and he burned them."
• Deuteronomy 7:5 — "You shall break down their altars and dash in pieces their pillars and chop down their Asherim and burn their carved images with fire."
Iconoclasm is now used pejoratively to describe anyone who challenges established norms.
In modern usage, "iconoclast" has become a compliment for rebellious nonconformists who challenge any tradition -- religious or secular. This trivializes the word's theological weight. Biblical iconoclasm is not generic rebellion; it is the specific, God-commanded destruction of objects used in false worship. Meanwhile, the churches that most need iconoclasm -- those filled with images, relics, and objects of veneration -- resist it most fiercely. The Reformers understood that the Second Commandment is not optional. Calvin and Zwingli ordered the removal of images from churches not out of cultural vandalism but out of obedience to God's explicit command. True iconoclasm is not anti-art; it is anti-idolatry.
• "Hezekiah's iconoclasm was not vandalism -- it was obedience. When the bronze serpent became an idol, the godly king destroyed it."
• "The Reformers practiced biblical iconoclasm by removing images from churches -- not because they hated beauty, but because they feared God."
• "Every generation needs iconoclasm -- not the secular kind that tears down tradition for sport, but the biblical kind that tears down idols for the glory of God."
