What is the role of visual aids in reformed theology worship?

One of the objections to the Catholic and Orthodox churches is that they use statues/icons as part of worship. (These objects are within churches, believers tend to have a few, etc) > John Calvin - Institutes of the Christian Religion, Book I, Chapter 11, "Impiety of Attributing a Visible Form to God—The Setting Up of Idols a Defection from the True God." But if you go to a reformed church, they have stained glass windows, depicting people or biblical events. It is even possible and likely that a picture book Bible could be there. ### So what exactly is the difference from the reformed protestant position? #### The "Epiphany" Window in the United Reformed Church in Somersville NJ See here for details. // *Side note, I do not understand why they call this the Epiphany window... it looks like the Nativity to me.* ### Mosaic Icon of the Theophany in the Monastery of Osios Lukas ### My old church First Presbyterian Church of Pittsburgh, above the massive organ pipes. Seriously, I crawled around up there... it's huge. This building was finished by them in 1905, and they claim their roots go back to 1758 on their website. ### Every Orthodox Church has this Icon of Jesus Pantocrator on the ceiling. This one is in St. Petersburg in a Russian Orthodox Church. ### St. Giles Cathedral - The Cradle of Presbyterianism in Scotland. The North Transept Window - Jesus Walking on the Sea ### Orthodox Icon of Jesus walking on the Sea, (from the website of the Orthodox church of Osaka )
