Judas Agrees to Betray Jesus
10Judas Iscariot, who was one of the twelve, went away to the chief priests, that he might deliver him to them.11They, when they heard it, were glad, and promised to give him money. He sought how he might conveniently deliver him.
Mark 14:10–11 recounts Judas Iscariot, one of the twelve apostles, approaching the chief priests to betray Jesus in exchange for money. The priests rejoice at the opportunity and agree to pay him, while Judas plans how to deliver Jesus conveniently, setting in motion the events leading to Jesus's arrest.
Judas does not fall in rage or passion—he walks toward betrayal with deliberate, calculating steps, teaching us that sin becomes mortal when we start planning how to commit it rather than fleeing it.
"He sought how he might conveniently (eukairōs) deliver him" — the Greek word means "at the right moment," "opportunely." This word will reappear in 14:44 when Judas gives the pre-arranged signal. The emphasis on timing reveals Judas's chief tactical concern: avoiding a public disturbance. He is not acting impulsively but surveilling, planning, biding. The word eukairōs stands in painful contrast to the kairos — the appointed time of salvation — that Jesus has been proclaiming since 1:15. Judas seeks a human opportune moment; he is working against the divine kairos even as he inadvertently serves it.
Typological and Spiritual Senses
In the typological sense, Judas figures several Old Testament antecedents. Most powerfully, he echoes Ahithophel (2 Samuel 15–17), the trusted counselor of David who betrayed him and then hanged himself — a pattern so precise that Psalm 41:9 ("Even my close friend, in whom I trusted, who ate my bread, has lifted his heel against me") is cited by Jesus at the Last Supper (John 13:18) as fulfilled in Judas. Joseph sold by his brothers for twenty pieces of silver (Genesis 37:28) provides another layer: the beloved of the father, handed over by those closest to him, descending into apparent death before a redemptive reversal. In the moral/tropological sense, these verses serve as a mirror for the soul: every deliberate mortal sin by a baptized Christian contains within it the structure of Judas's act — intimacy with Christ followed by a calculated turning away for some perceived gain.
Catholic tradition has wrestled seriously and specifically with the mystery of Judas, refusing both easy damnation and false comfort. The Catechism of the Catholic Church (§598) places the ultimate responsibility for Christ's death not on any one historical group but on "all sinners," and explicitly includes each Christian: "we must regard as guilty all those who continue to relapse into their sins." Judas is thus not a safely distant villain but an uncomfortable mirror.
The Church Fathers probed the paradox of divine foreknowledge and human freedom in Judas. Origen (Commentary on John) insists that God's foreknowledge does not compel Judas's choice — the prophecies are fulfilled through his freedom, not by overriding it. St. John Chrysostom (Homilies on Matthew) is characteristically fierce: Judas's sin was aggravated not by necessity but by ingratitude — he had witnessed every miracle, eaten at the same table, and still chose avarice. For Chrysostom, the chief priests' joy is equally damning: they rejoice at the very moment they become most culpable.
St. Thomas Aquinas (Summa Theologiae III, q. 47, a. 5) addresses whether Judas sinned more gravely than the crucifiers, concluding that while both sinned mortally, Judas's sin was distinguished by the intimacy of the relationship betrayed — an aggravating circumstance that intensifies its gravity. Aquinas also notes that God permits even this evil to draw out a greater good, without ever being its author.
The Second Vatican Council (Nostra Aetate §4) echoes this when it insists that "what happened in his passion cannot be charged against all the Jews" — the very logic that protects Judas from being scapegoated as representing any group applies universally. Pope Benedict XVI (Jesus of Nazareth, Part II) reflects movingly on whether Judas is finally lost, noting that the Church has never definitively taught his damnation, while the words of Jesus in Mark 14:21 ("it would have been better for that man if he had not been born") cast a deeply sobering shadow. The mystery remains open — and that openness is itself a pastoral and theological teaching about the gravity of free human choice.
These two verses invite the contemporary Catholic to examine not dramatic apostasy but the quiet architecture of betrayal. Judas does not fall in an instant; he seeks an opportune moment — which means he has been deliberating, rationalizing, and watching. The spiritual tradition calls this the second thought: the moment when the soul, having entertained a temptation, begins planning around it rather than fleeing it. Catholics today face analogous temptations: to trade faithfulness for convenience, to leverage religious proximity (ministry, community, sacramental access) for personal advantage, or simply to let the habit of sin calcify until the will is no longer shocked by what once horrified it.
The specific antidote this passage implies is vigilance over the interior life — what the Catechism calls "custody of the heart" (§2846). When a person begins seeking the moment to sin rather than resisting it, the Judas pattern is already underway. Confession, spiritual direction, and honest examination of conscience are the practical means the Church offers to break that trajectory before it reaches its bitter end. Judas's tragedy is not that he fell — Peter fell too — but that he did not return.
Commentary
Mark 14:10 — "Judas Iscariot, who was one of the twelve, went away to the chief priests"
Mark's placement of this scene is deliberate and devastating. It falls immediately after the anointing at Bethany (14:3–9), in which an unnamed woman performs an act of extravagant, prophetic love — pouring costly nard over Jesus and receiving his solemn praise. The juxtaposition is not accidental: Mark sets selfless devotion against calculated betrayal, love against transaction. The phrase "one of the twelve" (Greek: heis tōn dōdeka) is not a neutral identifier — it is a hammer blow. Mark has already introduced Judas by this designation at his calling (3:19), adding "who also betrayed him," so the reader carries that shadow throughout the Gospel. Here, the shoe drops. The phrase emphasizes not merely membership but intimacy: Judas shared table, road, mission, and teaching with Jesus. His defection is thus not the betrayal of a stranger but of an insider, a friend, a commissioned apostle.
The verb "went away" (apēlthen) is simple but significant. There is no narrated coercion, no visible supernatural compulsion at this stage — Judas walks. His action is framed by Mark as an exercise of will. He does not stumble into betrayal; he departs toward it. The chief priests (archiereis) were the Temple aristocracy, largely Sadducean, who held both religious authority and a precarious political accommodation with Rome. They had been seeking to arrest Jesus "by stealth" and kill him (14:1), but feared the crowd. Judas removes that obstacle.
Mark 14:11 — "They, when they heard it, were glad, and promised to give him money"
The Greek word for "glad" (echarēsan) is the same root used for joy and rejoicing throughout the New Testament — a word that elsewhere describes the disciples' response to the Risen Lord (John 20:20) or the angels' joy over a repentant sinner (Luke 15:7). Its use here is grimly ironic: the religious leaders of Israel rejoice not at good news but at the prospect of killing the Messiah. Their gladness is the mirror image of the joy that Jesus himself had brought to so many — now inverted in the service of death.
Mark mentions money (argyrion) without specifying the amount; Matthew 26:15 fills in the detail of thirty pieces of silver, the sum immediately evoking Zechariah 11:12 and the legal price of a gored slave (Exodus 21:32). Mark's reticence keeps the focus on the act itself rather than the arithmetic of treachery. The phrase "promised to give him money" also implies a deferred payment — the reward is contingent on delivery. Judas is now, in the most literal sense, a contractor.
