Those words appear behind me in this picture:
That picture is about a week old. Rick Segal took it while we were visiting Israel. It made us laugh because directly behind me is a Catholic church building in Jerusalem. You can navigate 360 degrees on Google maps and see that in the above picture my back is to the building’s entrance while I am directly facing the temple mount’s eastern wall.
The authorial intent of the words on the sign are probably to request that tour guides not talk openly inside the church building. But the words made me laugh because in some ways they encapsulate why Protestants are celebrating the 500th anniversary of the Reformation today.
Happy Reformation Day!
