The Wednesday before Holy Thursday is called Spy Wednesday because it is traditionally associated with Judas Iscariot secretly agreeing to betray Jesus to the religious leaders for thirty pieces of silver. The “spy” idea comes from Judas acting in a hidden, treacherous way rather than openly as a disciple.

Why the name stuck

In Christian Holy Week tradition, that Wednesday marks the moment Judas began acting like an informant, or “spy,” by arranging Jesus’ arrest. Different churches may also call it Holy Wednesday , Good Wednesday , or Great and Holy Wednesday.

In simple terms

  • Who: Judas Iscariot.
  • What happened: He made a deal to betray Jesus.
  • Why “Spy”: He was seen as secretly working against Jesus.
