How many days and nights are there between Friday Afternoon and Sunday Morning?
Clearly, even if you count Friday and Sunday as days, there are only two nights. According to the prophecy, the messiah would lie in the earth for three days and three nights as Jonah did in the belly of the fish (stop giggling - it's a quiz.)
So - here's the question:
Did the Catholic Church move the crucifixation ... uh, I mean crucifiction ... uh, crucifixion to Friday to deprive the faithful of a four day weekend or is God just not very good at math?
