Religion works expressively with symbols and metaphors, images that reflect and explain a metaphysical world, a world that transcends the primary senses and it is addressed to the mind and spirit. In time, church has defined and used symbols that now have obvious meaning for the practicing believer. "To read" a church logo you need to be aware of the meaning of the metaphors used, you need to be familiar with the icons in order to decipher the message.
