One of our readers pointed me to Catholic Church Conservation who have a unique little story, Pope's brother attends Latin Mass in Regensburg, complete with photographs.
The Mass took place in the Church of St. John in Regensburg, and was celebrated by one Fr. Walter Lang of Munich.
Here are a few of their pictures:
