In Western Christian tradition today goes by a number of names including Holy Wednesday and Good Wednesday. It can also be called Spy Wednesday because of certain events mentioned in the gospels. Unfortunately the Synoptic Gospels and John’s Gospel diverge considerably on the order and timing of the major events of Holy Week although they generally agree concerning the events themselves with some minor variations as to particulars.
According to Mark (12:3-10) on the Wednesday before his death Jesus was in Bethany in the evening:
3 While he was in Bethany, reclining at the table in the home of Simon the Leper, a woman came with an alabaster jar of very expensive perfume, made of pure nard. She broke the jar and poured the perfume on his head. 4 Some of those present were saying indignantly to one another, “Why this waste of perfume? 5 It could have been sold for more than a year’s wages and the money given to the poor.” And they rebuked her harshly. 6 “Leave her alone,” said Jesus. “Why are you bothering her? She has done a beautiful thing to me. 7 The poor you will always have with you, and you can help them any time you want. But you will not always have me. 8 She did what she could. She poured perfume on my body beforehand to prepare for my burial. 9 Truly I tell you, wherever the gospel is preached throughout the world, what she has done will also be told, in memory of her.”
10 Then Judas Iscariot, one of the Twelve, went to the chief priests to betray Jesus to them. 11 They were delighted to hear this and promised to give him money. So he watched for an opportunity to hand him over.
The chronology in John is very different. There the event happens before the triumphal entry on Palm Sunday, but in some Western liturgical traditions Mark’s chronology is accepted and gives us the name Spy Wednesday where “spy” means essentially “ambush” or “betrayal.” Two events are linked in Mark’s narrative – the anointing of Jesus and Judas’ decision to betray him – but in John the relationship is much clearer, and some added details have caused a lot of speculation.
In John it is Judas who complains about the waste of the perfume but he is accused of hypocrisy in that he didn’t want to help the poor but himself. Seeing the lost opportunity enrich himself he goes to the Sanhedrin seeking a bribe for betraying Jesus’ whereabouts. The general point is that Jesus preached openly in the daytime and generally infuriated the authorities with his message which was harshly critical of the status quo from which they
