The Church of Saint Vincent de Paul Parish in Seward, Nebraska has a series of stained glass windows on the beatitudes. You can see them on their Web site. It might be an interesting experiment to have your students draw their own version of the beatitudes in the style of stain glass windows. Let me know if you do something in this sense. I would love to see the results!
