Christmas-less Historical Fiction Fantasy

I remember hearing about a book/ series that examined history... as if prior historical events had different outcomes (eg: Allies lost WWII, Spanish Armada beat the English, etc.)

What would a book be like about 2014... if Jesus had never been born?

It's probably so massive a historical change that it'd be all but impossible... (Would science/ technology have developed as far? Under what conditions? What religions would still be existing? Not Islam. Germanic? Celtic? Which belief systems would rule?)

The origins of virtue?

Did you know "virtue" comes from the Latin word for man, "vir"? 

"moral strength, high character, goodness; manliness; valor, bravery, courage (in war); excellence, worth." 

Órale. That´ll preach.

p.d. "Wyclif Bible has virtue where KJV uses power."
