Re: "It seems knowledge of the NT is sadly lacking these days..."
Well, it might not be called that any more, but it's still current and an ongoing concern. Many people live by the code even if they don't realise it. The sign of the cross, although reworked many, many times throughout history, is still easily recognisable in our everyday lives. As it says in the good book... “If you can't make it good, at least make it look good.” NT 17763.379
