Superstition, in all times and among all nations, is the fear of a spirit whose passions are those of a man, whose acts are the acts of a man; who is present in some places, not in others; who makes no places holy and not others; who is kind to one person, unkind to another; who is pleased or angry according to the degree of attention you pay him, or praise you refuse to him; who is hostile generally to human pleasure, but may be bribed by sacrifice of a part of that pleasure into permitting the rest. This, whatever form of faith it colors, is the essence of superstition.
John RuskinThere is no harm in anybody thinking that Christ is in bread. The harm is in the expectation of His presence in gunpowder.
John Ruskin
