The history of the word, according to Dictionary.com:
Eikonoklast?s, the ancestor of our word, was first formed in Medieval Greek from the elements eik?n, “image, likeness,” and -klast?s, “breaker,” from kl?n, “to break.” The images referred to by the word are religious images, which were the subject of controversy among Christians of the Byzantine Empire in the 8th and 9th centuries, when iconoclasm was at its height. In addition to destroying many sculptures and paintings, those opposed to images attempted to have them barred from display and veneration. During the Protestant Reformation images in churches were again felt to be idolatrous and were once more banned and destroyed. It is around this time that iconoclast, the descendant of the Greek word, is first recorded in English (1641), with reference to the Byzantine iconoclasts. In the 19th century iconoclast took on the secular sense that it has today: a person who attacks cherished beliefs, traditional institutions, etc., as being based on error or superstition.

I do not adhere to the traditional or modern concepts of the iconoclast. I do not tout the name as a label or use it to define who I am. I carry it as a reminder.

It is a reminder to keep all powers in check, be they church, government, revolutionaries or myself. If the church clings to images or ideas that are founded on false principles, I feel it is our duty to destroy those images or ideas. One of the primary methods of this destruction is to expose the foundations of these concepts to be false. In the same way, if I cling to images or ideas that are false or otherwise founded on false principles, it is my duty to break those down as well.

I am not a true iconoclast, because I only attack those beliefs or institutions that are based on error. I also hold my determination of said error until the fault has been clearly proven. The majority of my iconoclastic nature manifests itself not in attacks upon cherished beliefs or institutions, but in the questioning of their validity. My path may dance a thin line between heresy and piety, but it is the only path I can take.
