The good done that day will never be equaled.
No other day in the history of man has such a selfless deed been done for so undeserving a people ie Jesus dying on the cross
In truth, nobody knows why that term has evolved. Some of the lingua franca suggestions are as those above but generally in the Church itself it is considered a �good� day for mankind, a day to remember when Jesus� suffering enabled our own salvation. As nannyjill has said really.
Hardly for mankind,Octavius. Not for me, for example. Because I don't believeth in him I shan't be saved, apparently, though from what no-one is clear.
No doubt I will find out one day. Or maybe not.
Meanwhile you religionists must not try to include the rest of us in your superstitions. It's very ill-mannered.
