Today is Spy Wednesday for 2013
It refers to the opening from the Gospel at today's Mass:
" Then went one of the twelve, who was called Judas Iscariot, to the chief priests, And said to them: What will you give me, and I will deliver him unto you? But they appointed him thirty pieces of silver. And from thenceforth he sought opportunity to betray him." Matthew 26:14-16
In short, Judas became a spy or double agent, hence the name.
