Lectionary.pro for the Fourteenth Sunday after Pentecost, Proper 17, Year A

Hold on to your seats this week — the gospel makes a hard right toward Jerusalem and never looks back! This is the immediate turn from last week. Peter has just confessed Jesus as the Messiah. Now Jesus begins to teach what that means — suffering, death, resurrection. Peter is scandalized. Jesus is direct. The way of the cross gets named, and the same disciple who was blessed six verses ago is called Satan for objecting to it.

The Old Testament tracks both give us people called to hard tasks. Track One brings us Moses at the burning bush — the divine name revealed, the reluctant prophet given his commission. Track Two brings us Jeremiah’s lament — a prophet accusing God of being like a deceitful stream that goes dry when you need it most, and God’s bracing rather than soothing response.

The Epistle continues Paul’s practical instructions in Romans 12. After last week’s call to living sacrifice, now come the specifics: let love be genuine, bless those who persecute you, weep with those who weep, and overcome evil with good.

For preachers continuing a series: last week’s confession is followed this week by its cost. This is the turn from “who is Jesus?” to “what does following this Jesus mean?”

First Reading (Track One) — Moses at the Burning Bush

Moses is tending his father-in-law’s flock in the wilderness of Sinai. He notices a bush that is on fire but not consumed, and turns aside to look. From the bush, God calls his name. God has heard the cry of the Israelites in Egypt; God is sending Moses to bring them out. Moses offers a series of objections — starting with “who am I to go?” and moving to the deeper question, “what is your name?” God’s answer to the second is one of the most enigmatic sentences in the Bible: I AM WHO I AM — or I will be who I will be — a name whose tenses refuse to settle.

1. The bush is on fire but not consumed. Moses turns aside to look. That turning aside is the whole beginning of the story. Where in your congregation might God be waiting for a turn of attention that no one has yet made?

2. Moses’s first objection is “who am I?” God does not answer that question. God changes the subject to “I will be with you.” The confidence for the task, in this text, does not come from the sender knowing anything special about himself. It comes from the promise of God’s presence. What does it look like to preach a call that does not require self-confidence, only God’s promise?

3. The divine name — “I AM WHO I AM” — is deliberately unfixed. The Hebrew can mean “I am who I am,” “I will be who I will be,” or “I will be what I will be.” The name refuses to settle. Where has your congregation been trying to freeze God into a definition God has refused to be frozen into?

4. God calls Moses by name — the same Moses whose past includes murder, exile, and running away. This is not a call to a person who has proven himself. It is a call to a person whose past is complicated. Where in your congregation are people quietly assuming their past disqualifies them from what God might be calling them to now?

• The burning bush has become such a familiar image that it can be preached as a metaphor for any inspiring experience. It is more specific than that — a genuine encounter at a particular time and place with a particular commission attached.

• “I AM WHO I AM” is contested territory in translation. Do not preach a confident philosophical reading of the divine name; the Hebrew resists that.

• Moses’s objections to the call are legitimate. He is not portrayed as faithless for offering them, and God takes them seriously. Do not use this passage to shame people who have their own honest objections to what they are being asked to do.

The Psalm (Track One) — Remember the Wonders

This section of the great remembering psalm focuses on the descent of Jacob’s family into Egypt and God’s raising up of Moses and Aaron to lead them out. The selected verses call the people to remember the wonders God has done — with Abraham, in Egypt, through Moses — and close with a single “hallelujah.”

1. The psalm remembers Moses’s story from a great distance — after everything worked out, after generations have passed. What might it mean for your congregation to make the same practice of long remembering, so that today’s uncertain calls can be trusted to become tomorrow’s remembered deliverances?

2. The psalm names Moses as God’s “chosen” and Aaron as the one God “sent.” This is theological language for what looked, in the moment, like the reluctant conscription of two brothers who did not want the job. Where in your congregation has “chosen by God” language obscured how much resistance actual calls have met?

• The psalm’s cheerful retrospect does not undo the pain the Israelites lived through in Egypt. Do not let the celebration minimize present suffering in your congregation.

First Reading (Track Two) — Jeremiah’s Lament

Jeremiah is in real distress. He accuses God of being unreliable — like a stream that goes dry when you need it most, “deceitful waters that cannot be trusted.” He has been faithful, he says. He has eaten God’s words. He has not sat with the merrymakers. And still he is in pain. God’s response is bracing rather than tender: if you turn back to me, I will take you back. If you utter what is precious and not what is worthless, you will serve as my mouth. And I will make you a fortified wall of bronze to this people — they will fight against you, but they will not prevail, for I am with you.

1. Jeremiah accuses God to God’s face — of being unreliable, of failing him, of being like a stream that runs dry. This is not sinful speech; it is the honest lament of a prophet in pain. Where in your congregation has honest complaint to God been mistaken for faithlessness?

2. God’s response is not soothing. It does not include an apology or a comforting explanation. It includes a call to return and a strengthening for the road ahead. What might your sermon do with a God who does not always answer our pain with sympathy but sometimes with a call to keep going?

3. God promises Jeremiah he will be like a fortified wall of bronze against opposition. Not that opposition will go away. That he will be strong enough for it. Where in your congregation are people needing strength for opposition that is not going away?

• Jeremiah’s lament should not be preached as a warmup to a happy ending. The pain is real and the response is a call to keep going, not an assurance that the pain will end.

• “Fortified wall of bronze” imagery has been used to encourage rigidity where flexibility was needed. The bronze wall is protection against opposition, not against learning.

The Psalm (Track Two) — I Have Walked in Integrity

A psalm of protested innocence and love for God’s house. The psalmist asks God to vindicate him — he has walked in integrity, he does not sit with the wicked, he washes his hands in innocence. And he loves the house where God’s glory dwells. It is a confident psalm, close to boasting, and honest about what the psalmist most wants.

1. The psalmist’s confidence sounds surprising to modern ears used to more humble language in prayer. But there is a real place in the psalter for asking God to notice when we have tried to be faithful. Where has your congregation been too shy to name, in prayer, the ways they have tried to be honest with God?

2. “I love the house in which you dwell, O Lord, and the place where your glory abides.” That is unabashed love for the community of worship. What might your sermon do with the specific love of the church as a spiritual practice worth honoring?

• The psalmist’s claim of innocence has been used to prop up self-righteousness. Read in context, it is a plea for a fair hearing, not a claim to moral perfection.

The Epistle — Let Love Be Genuine

Paul continues the practical section of Romans 12 — one of the most concentrated ethical passages in his letters. Let love be genuine. Hate what is evil; hold fast to what is good. Love one another with mutual affection; outdo one another in showing honor. Be joyful in hope, patient in suffering, persevering in prayer. Extend hospitality to strangers. Bless those who persecute you — bless, and do not curse. Rejoice with those who rejoice; weep with those who weep. Do not repay evil with evil. So far as it depends on you, live peaceably with all. And the closing: do not be overcome by evil, but overcome evil with good.

1. “Let love be genuine.” That is Paul’s opening. Not “let love be adequate.” Not “let love be present.” Genuine — un-performed, un-simulated, the real thing. Where in your congregation has the love been well-intentioned but not quite genuine, and how might Paul’s opening word press on that?

2. “Weep with those who weep” is often quoted; “rejoice with those who rejoice” is often skipped. Weeping is expected; rejoicing at someone else’s joy is harder. Where in your congregation has envy quietly kept people from rejoicing when their neighbors flourish?

3. The closing — “do not be overcome by evil, but overcome evil with good” — is Paul’s summary of Christian resistance. Not retaliation. Not passive absorption. Active good, offered in response to what is wrong. What might your sermon do to make that both concrete and credible in a world where retaliation feels satisfying?

• “Bless those who persecute you” has been used to tell people to endure abuse. That is a serious misuse. Paul is describing a posture toward hostility in the world, not endorsing continued relationship with people who are harming you.

• “So far as it depends on you, live peaceably with all” contains an important qualifier — “so far as it depends on you.” Some peace is not available because the other party does not want it. Paul does not require Christians to manufacture what the other side refuses.

The Gospel — Get Behind Me, and Take Up Your Cross

Immediately after Peter’s confession, Jesus begins to teach the disciples that he must go to Jerusalem, suffer at the hands of the elders and chief priests, be killed, and on the third day be raised. Peter takes him aside and rebukes him: “God forbid it, Lord! This must never happen to you.” Jesus turns and says the sharpest word he ever says to a disciple: “Get behind me, Satan! You are a stumbling block to me, for you are setting your mind not on divine things but on human things.” Then he speaks to all the disciples: those who want to become his followers must deny themselves, take up their cross, and follow him. Those who want to save their life will lose it, and those who lose their life for his sake will find it. What does it profit to gain the whole world and lose your soul?

1. The turn from last week is immediate and jarring. Peter has just been blessed for confessing Jesus as the Messiah; now he is called Satan for objecting to the Messiah’s actual road. Confessing Christ, Matthew is saying, is not the same as following the Christ we have confessed. How might your sermon hold together the great confession of last week and the correction of this one?

2. Peter’s rebuke is not evil; it is protective. He wants to keep Jesus from being killed. But he is setting his mind on human things — a natural, understandable concern for his teacher’s safety — and Jesus names it as a stumbling block. Where in your congregation has protective love for a person or an institution quietly blocked what God was doing?

3. “Take up your cross” is language we have to handle with care. The cross was a real Roman instrument of execution. It was terrifying. Jesus is not offering a metaphor for daily annoyances. He is naming a life that follows him in a direction the world will not always thank you for going. What does it look like to preach this without either domesticating it into inconvenience or making it inaccessible to ordinary lives?

4. “Those who want to save their life will lose it; those who lose their life for my sake will find it.” This is one of the most repeated sayings of Jesus, and one of the most abused. The saving Jesus promises is not the reward for a sufficiently self-denying life. It is the shape of a life ordered toward him rather than toward self-preservation. Where might your congregation be preserving lives that are already shrinking, when Jesus is inviting them to lose lives that would open?

• “Deny yourself” and “take up your cross” have been used, throughout church history, to tell abused women to stay in dangerous marriages, enslaved people to accept their bondage, and the poor to endure exploitation. This is a grievous misuse. Preachers must be clear that Jesus is speaking to disciples about the cost of following him, not blessing anyone else’s exploitation.

• “Get behind me, Satan” has sometimes been used as a script for shutting down people who disagree with us. Jesus is speaking to his closest friend about a specific issue — the necessity of the cross. He is not modeling how to end arguments with people whose theology annoys us.

• “Gain the whole world and lose your soul” is famous but often preached in a way that reduces it to individual moralism. In Matthew, “life” is closer to “whole self” than to “immortal soul.” The trade-off is not primarily about heaven; it is about what kind of person we are becoming.

The Gospel is the natural center — the immediate turn from last week’s confession to this week’s cost. Peter’s rock-solid answer is followed by the road Jesus intends to walk with it. This is the pivot in Matthew’s Gospel from Galilee toward Jerusalem, and everything else will be read in its light.

On Track One, Moses at the burning bush pairs with the Gospel in a specific way. Both texts are about calls that come with resistance. Moses objects that he is not adequate; Peter objects that Jesus should not have to suffer. Both objections are met with a call to trust God’s presence rather than the objector’s understanding of the situation. The bush that is on fire and not consumed is a picture of the God who calls Jesus to a cross that will not consume him either.

On Track Two, Jeremiah’s lament and God’s bracing response give us a picture of what following God actually feels like from the inside. The prophet in pain, the God who does not soothe but strengthens, the fortified wall against opposition that will not disappear — this is the shape of the road Jesus is naming in the Gospel. Peter wants to keep Jesus off Jeremiah’s road. Jesus is walking it deliberately.

Romans 12 sits inside the day as the practical extension. If Peter’s confession is true and Jesus’s road is what the confession means, then Christian community life has to be shaped by this — genuine love, blessing of enemies, overcoming evil with good. Paul is describing what a community of cross-shaped disciples actually looks like.

For preachers continuing a series: last week the summer arc reached its climactic confession. This week the confession is corrected — or rather, its true meaning is revealed. Following the Christ we have confessed will not look like keeping him safe. It will look like walking with him toward the road he chose.
