Just so we're clear on that.
Of course this is the twenty-first century Episcopal Church, where rubrics exist to be set aside as the priest pleases, so the mere fact that the BCP tells us to do something doesn't amount to any actual requirement. And gosh darn, it wouldn't be "inclusive" to have all those C&E visitors be asked to state their faith in public, not to mention their lapsed and irreligious relatives. Not only that, it speeds up the service by a precious two minutes to leave this out.
Come on, clerics. It is obvious that on the two greatest feasts of the year, those in attendance should be called to recommit to the mysteries of the faith, as they are called to do on every Sunday of the year. Those who cannot do so can stand silently, and they can absent themselves from the altar rail in turn. To do otherwise shows our own lack of commitment to the faith.
