According to Carlos Eire
And now I understand much better the role that symbols play in religion, not just in Christianity but in all religions. You know, symbols encode, deep deep truths and allow us to perceive them in a non-rational way. And by non-rational, I don’t mean irrational. I actually mean that these symbols speak to us at a level that is deeper, and affects us and shapes our personality much more than any logical discourse could. You know, the United States is a very symbolically impoverished culture. So most Americans have trouble understanding symbols and how symbols affect them. But people who are in advertising have it all figured out.
They know. They know. They know exactly what us religious scholars know about how symbols affect people and they use them to sell stuff to us.
