Art reveals truth. It makes the invisible visible. It speaks to souls on the level of the imagination, making abstract concepts tangible, helping ideas become things we can see and hear.
In the dramatic arts, that happens through story and speech and song. The true and the beautiful presented on stage or on film, become windows to God. The tales told and the characters represented move, inspire, and challenge. They also contain within them the soul of a culture, revealing what a culture is and holds most dear.
