"Catholics use statues, paintings, and other artistic devices to recall the person or thing depicted. Just as it helps to remember one’s mother by looking at her photograph, so it helps to recall the example of the saints by looking at pictures of them. Catholics also use statues as teaching tools. In the early Church they were especially useful for the instruction of the illiterate. Many Protestants have pictures of Jesus and other Bible pictures in Sunday school for teaching children. Catholics also use statues to commemorate certain people and events, much as Protestant churches have three-dimensional nativity scenes at Christmas. "
