Everyone understands God in their own way. So, one person's understanding is another person's misunderstanding, and what is a god to some is but an idol to others. Idea idols recreate the infinite source of all in our minds – making the infinite not so infinite anymore! And ridged concepts, no matter how well-intended, can be just as idolic as any image carved in wood or stone.
Images can be a way to visualize, conceptualize and worship the infinite. However, whatever the significance of the image, the early Christians (and more recently, Muslims) took it upon themselves to destroy what they understood/misunderstood to be “false gods.”
Iconoclasm is basically cataclysm for icons and idols. It is the “deliberate destruction within a culture of the culture's own religious icons and other symbols or monuments, usually for religious or political motives.”
History records various periods of Iconoclasm, However, what it can't tell us is how idea Iconoclasm will play out as truth-seekers target conceptual idolatry around them today. This quest is developing into a new Reformation as Christians join hands with others and mount a crusade to dethrone all the old idols from the mind.
