I am wrong, totally wrong, as my old friend, Professor Emeritus John Troyer pointed out to me a few moments ago in a characteristically generous email message. It is Mary, not Jesus, who is said to have been immaculately conceived.
Rats! I hate it when I am wrong, but wrong is wrong, and there is no getting around it.
My profoundest apologies. Fortunately not many people have found their way back to my blog yet.
