The Request of James and John: True Greatness Through Service (Part 1)
35James and John, the sons of Zebedee, came near to him, saying, “Teacher, we want you to do for us whatever we will ask.”36He said to them, “What do you want me to do for you?”37They said to him, “Grant to us that we may sit, one at your right hand and one at your left hand, in your glory.”38But Jesus said to them, “You don’t know what you are asking. Are you able to drink the cup that I drink, and to be baptized with the baptism that I am baptized with?”39They said to him, “We are able.”40but to sit at my right hand and at my left hand is not mine to give, but for whom it has been prepared.”41When the ten heard it, they began to be indignant toward James and John.42Jesus summoned them and said to them, “You know that they who are recognized as rulers over the nations lord it over them, and their great ones exercise authority over them.
Mark 10:35–42 depicts James and John requesting positions of honor at Jesus's right and left in His glory, not understanding that such privilege requires sharing in His suffering and death. Jesus teaches all the disciples that kingdom power operates through sacrificial service, not domination, establishing a radically different model of authority than worldly rulership.
Ambition for honor in God's kingdom kills you before it exalts you — the thrones James and John wanted were occupied, at Calvary, by dying criminals.
Verse 39 — "We Are Able" Their confident reply, "We are able," is simultaneously admirable and tragic. It is not false bravado in a cynical sense — Jesus does not contradict it. He affirms that they will indeed drink His cup and share His baptism, a prophecy confirmed in history: James became the first apostolic martyr (Acts 12:2), and John, though he did not die as a martyr, was exiled to Patmos and tradition records multiple attempts on his life. Yet at this moment they speak out of ignorance. Their willingness, though sincere, has not yet been purified by Gethsemane and Calvary.
Verse 40 — A Mystery of Divine Preparation "To sit at my right hand and at my left hand is not mine to give, but for whom it has been prepared." This verse has generated significant patristic discussion. It does not mean Jesus lacks authority — such an interpretation would contradict the consistent witness of the New Testament to Christ's divine prerogatives (cf. Matthew 28:18). Rather, Jesus is saying that the places of ultimate eschatological honor belong to a divine decree that operates according to a logic of sacrifice and redemptive suffering, not patronage. The Father's eternal plan of election determines these places. The Church Fathers, including Origen and Chrysostom, read this as a teaching on the Father's inscrutable Providence and the merit-forming nature of suffering borne in union with Christ.
Verses 41–42 — Indignation and the World's Power The "indignation" of the ten is revealing: it is almost certainly not moral outrage but competitive jealousy — they are angry that James and John tried to get there first. Jesus "summons" them all (the verb proskaleomai in Mark typically marks a solemn, authoritative teaching moment; cf. 3:13, 7:14, 8:34) and offers a sociological diagnosis of worldly power: rulers "lord it over" (katakurieuousin) and great ones "exercise authority" (katexousiazousin). The kata- prefix intensifies both verbs — it is domination, power pressed down upon others. Jesus is not describing all authority as illegitimate but exposing the domination-model of power as fundamentally incompatible with the kingdom He is inaugurating.
Catholic tradition has read this passage as foundational to the theology of ecclesial authority and the nature of Christian leadership. The Catechism of the Catholic Church (§ 786) teaches directly from this passage: "The Lord also made servants and stewards of his mysteries of salvation. Christ, 'though he was rich, yet for your sake he became poor' (2 Cor 8:9). Every member of the Church must follow him." The passage is central to the Church's understanding that authority within the Body of Christ is always a diaconia — a ministry of service — not a privilege of dominion.
Pope St. Gregory the Great, in his Regula Pastoralis, drew heavily on this Markan trajectory to argue that the bishop's authority is precisely a burden assumed in love for souls, not a position of honor to be sought. He warned that those who seek the summit of governance for the sake of preeminence place themselves in profound spiritual danger.
St. Ignatius of Antioch, writing to communities under his pastoral care, explicitly echoes the cup-imagery of verse 38 when he writes to the Romans longing for martyrdom: "I am God's wheat, and I am ground by the teeth of wild beasts so that I may be found pure bread of Christ." He understood his own martyrdom as participation in the cup Jesus described to James and John.
The Second Vatican Council, in Lumen Gentium § 27, teaches that episcopal authority is to be exercised "in the manner of a servant" (ad instar servi), citing this passage and its culmination in verse 45. The munus of governance in the Church is never separable from the munus of suffering service.
Theologically, the "cup" prepared by the Father (v. 40) also speaks to the Catholic understanding of predestination and merit operating together without contradiction: the places in glory are divinely prepared, yet the disciples must freely drink the cup to occupy them. This is entirely consistent with the Tridentine and Thomistic synthesis on grace and free cooperation.
This passage confronts contemporary Catholics at a very specific point: the persistent temptation to seek honor, recognition, and preferential position within the Church itself. Whether in parish councils, diocesan roles, lay movements, or even family life, the dynamic James and John enact — "reserve the best seat for me" — runs deep in human nature. Jesus's response is not to abolish legitimate hierarchy but to transfigure its motivation entirely. Ask yourself: when you serve in any capacity in the Church or your community, are you quietly keeping score of recognition? Are you indignant, like the ten, when someone else receives the acknowledgment you wanted?
The cup is also intensely personal. Jesus is asking every disciple: are you willing to have your ambitions, your planned futures, your reputation submerged — baptized — into His? The saints who answered "yes" to that question did not do so once, dramatically, but in the daily choices of ordinary life: in the parish volunteer who serves without being thanked, in the parent who sacrifices a career for a child's care, in the Catholic professional who forgoes a promotion rather than compromise integrity. These are the cups. These are the baptisms.
Commentary
Verse 35 — The Blank-Check Request The approach of James and John ("came near to him") mirrors the posture of petitioners before a king, yet their opening gambit — "do for us whatever we will ask" — is startling in its presumptuousness. They do not first state their request but seek a prior commitment, a rhetorical strategy that reveals both intimacy with Jesus and a profound misunderstanding of who He is. Mark notes they are "the sons of Zebedee," the same pair whom Jesus named Boanerges ("sons of thunder," 3:17), a detail that now rings with irony: their thunder here is the thunder of ambition, not of the Spirit.
Verse 36 — Jesus's Gentle Reversal Rather than rebuking them outright, Jesus turns the blank-check request back on them: "What do you want me to do for you?" This precise question will reappear in verse 51 when Jesus asks the same thing of blind Bartimaeus — a deliberate Markan parallel that contrasts the spiritually blind disciples (who have eyes but cannot see the kingdom's true shape) with the physically blind beggar who sees clearly that Jesus is Lord. Jesus's patience here is itself a teaching: He draws out the request rather than pre-empting it, allowing the disciples' misunderstanding to surface fully.
Verse 37 — Thrones of Glory "Grant to us that we may sit, one at your right hand and one at your left hand, in your glory." The request echoes Jewish expectations of the messianic banquet and the eschatological court of the Son of Man (cf. Daniel 7:13–14), where the Messiah's closest companions would share in His royal splendor. "Your glory" (Greek en tē doxē sou) likely refers to the moment of the kingdom's full manifestation. The irony that Mark intends his reader to feel is sharp: two men will indeed be positioned at Jesus's right and left in His "glory" — but they will be crucified thieves (15:27), and the throne will be a Cross. James and John are asking for exactly what Jesus will give, but in a form they cannot yet imagine.
Verse 38 — The Cup and the Baptism Jesus's response pivots everything. "You don't know what you are asking" is not condescension; it is diagnosis. The "cup" (potērion) in Old Testament usage is frequently a cup of divine wrath or suffering poured out upon those who undergo judgment or bear the weight of God's purposes (cf. Psalm 75:8; Isaiah 51:17, 22; Jeremiah 25:15–17). Jesus uses it again in Gethsemane (14:36): "Take this cup from me." The disciples' breezy confidence will collapse there. "Baptism" (baptisma) as a metaphor for overwhelming suffering draws on the Hebrew idiom of being submerged or overwhelmed by waters (cf. Psalm 42:7; 69:2, 15; Luke 12:50, where Jesus says, "I have a baptism to be baptized with, and how I am constrained until it is accomplished!"). Together, cup and baptism form a double image of the Passion as total immersion in suffering and redemptive death.
