When did Satan enter Judas?

What follows is one scholar’s way of reading this disagreement — a critical-historical view that often concludes the texts genuinely disagree.

How critical scholarship weighs this: Widely regarded as a genuine contradiction

This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.

The two Gospels place the same singular event — Satan's entry into Judas — on opposite sides of the Last Supper. Luke 22:3-7 sets it explicitly before the meal: "Then entered Satan into Judas surnamed Iscariot," after which Judas goes to the chief priests and captains to negotiate the betrayal (22:4-6), and only then "came the day of unleavened bread, when the passover must be killed" (22:7), with the meal itself following in 22:14ff. The satanic entry in Luke thus precedes the Supper by what the narrative presents as a span of days. John 13:27 sets it during the meal: after Jesus dips and hands Judas the sop, "Satan entered into him," and Judas immediately goes out — "and it was night" (13:30), John's loaded close to the scene. Same agent, same act, opposite timing.

The standard harmonization, advanced by Gleason Archer among others, posits two distinct satanic entries: an initial entry that planted the betrayal scheme (Luke 22:3) and a second, sealing entry at the Supper (John 13:27). The case for it leans on John 13:2, which notes that before the meal "the devil [had] already put into the heart of Judas Iscariot... to betray him" — suggesting a diabolical influence preceding the climactic entry of 13:27. That is the strongest form of the argument, and it deserves to be stated fairly: John himself appears to distinguish an earlier prompting (13:2) from the entry proper (13:27). But the harmonization runs into the texts' own language. Luke 22:3 narrates a single, complete entry with no hint that a further entry is to come; John 13:27 narrates a single entry with no "again." And crucially, the move requires coordinating Luke's pre-Supper entry with John's pre-Supper prompting and then John's at-Supper entry into a three-beat sequence that neither evangelist actually narrates. Luke knows nothing of a second entry; John's 13:2 is a prompting of "the devil," not a narrated "entry," and is its own clause distinct from the entry in 13:27.

The more economical reading, set out in Brown's *Death of the Messiah* and Fitzmyer's Anchor commentary on Luke, is that Luke and John independently deployed the same theological tool to solve the same problem. Early Christianity faced an acute difficulty: how could one of the Twelve, chosen by Jesus, betray him? Attributing the act to satanic agency removed the scandal from Jesus' judgment and from human freedom alike, and both evangelists reached for it. Luke front-loads the possession so that Judas's entire trajectory toward betrayal is demonically driven from the outset, integrating it with Luke's framing of the passion as a cosmic contest (note Luke 22:53, "this is your hour, and the power of darkness"). John locates it at the Supper because John builds the meal into the dramatic hinge of the narrative: the morsel marks Judas, Satan enters, Judas exits "into the night," and the hour of glorification begins (13:31). Each placement serves the evangelist's distinct theology, which is precisely why they differ.

The two-entries harmonization is the characteristic apologetic move of multiplying events to dissolve a discrepancy, and it founders on the singular, definitive way each text narrates the entry.

Where the critical reading lands: genuine contradiction in placement, best explained as independent redactional use of a shared Judas-and-Satan tradition.
