Now THERE'S a greeting that may have some people scratch their heads and go "huh?" Some who remember, or still attend Mass according to, the 1962 Roman Missal (Tridentine Mass) might remember the name Spy Wednesday. I had never heard of it until seeing a Tridentine calendar in the sacristy at Holy Name a few years back.
It doesn't take much to realize the course of events within Holy Week to guess why the Wednesday in Holy Week was named Spy Wednesday. Consider this - the Last Supper (Holy Thursday) obviously took place before the Lord's Passion and Death (Good Friday). It is just before the Last Supper when, according to Gospel accounts of the Passion, hit man Judas was hired by the mafia of chief priests and elders, for thirty silver pieces, to hand Jesus over. It was on that day, Spy Wednesday, when the "deal was made".
Tomorrow we recall at Supper: one of you is about to betray me.
