text: The Episcopal service of an Episcopal community in my city that I watched on YouTube was celebrated ad orientem. I suspect it's more common among Anglicans that at Catholic Novus Ordos. They seem more eager to not discard their traditions as many Catholics are won't to do (wrecking high altars and altar rails). 
  
  And yes, the freak out among progressive liturgists when Cardinal Sarah suggested more priests celebrate ad orientem illustrates Welby's joke exactly.
