This is St. John's Baptist Church located at an old, abandoned coal mining town here in West Virginia (near Beckley). It was built in 1918. Sadly, it collapsed just a few months after these pics were taken. Here is an incredible slideshow with more views: https://www.flickr.com/photos/zachsdame/sets/72157621026829035/. This has turned out to be the most re-pinned pic of any photo I've ever posted on Pinterest!
Altar at Cathedral of St. John the Baptist -- Savannah, GA. Beauty bears witness to good stewardship made possible only by Love. The most extravagant cathedral and more humble traditional churches have that in common. Iconoclasm will always be ugly, no matter the price tag. That we are to be temples of the Holy Spirit works in reverse, too: we might see the interior of a beautiful Catholic church as a reflection of the rightly ordered, abundant spiritual life that Catholicism enables.
