This Catholic Bishop is speaking to his churchgoers when a man calmly strides up to the front of the room and suddenly punches the Bishop right in the face.
There's no clear evidence in the video explaining why the man might have wanted to punch the Bishop, but it looks like everyone was relatively unharmed by the end of the encounter and the assailant was promptly escorted out of the building by police officers.
