If you have a picture in your home, does that mean you are worshipping them? It is not fair to say that people worship the pictures , the actual pictures. These pictures and statues are merely to view to bring to mind a picture. If you love your children and have pictures of them, you are not worshipping them by exhibiting their pictures. It makes you happy to view them when they are not visable. It is the same for the people in the church. They love the Saints, Apostles, Mary, Joseph, etc. Is it any wonder they want to view them in picture form? Does everyone who has a picture of a tree in their homes need to be accused of worshipping their trees? These pictures are helpful in teaching as well. Sometimes pictures are put in places where people go to pray to the saint, they are not praying to the pictures, or in some cases statues, but to the memory of the Saint. Sometimes parents allow their children to ask about the pictures or statues, that is the way children and others may have their curiousity about the Saints, etc, increased and thence they ask and learn through the view of the pictures or statues. Also, some pictures, and statues are used to show that an area is a specific place to go. Such as , those who want to pray up at the alter will go to an area where Mary is, they cannot pray to the priest, they would then be accused of worshipping the priest, or be interupting the preist. So they go where they can pray up at the alter but not directly in front of the area where the preist are leading the mass.
