The Vineyard

The Vineyard of the Lord

✛ August 16, 2026 Our Saviour Lutheran Church Nineteenth Sunday after Pentecost, Proper 22
Gospel: Matthew 21:33–46  ·  Old Testament: Isaiah 5:1–7  ·  Epistle: Philippians 3:4b–14
How this session works. We begin with the Collect of the Day, which frames the theological theme of God’s vineyard and the rejection of His Son. We then spend the majority of our time in the Gospel reading, Matthew 21:33–46, which is the centerpiece. From there, we step back into the Old Testament reading from Isaiah 5:1–7 to discover how God first planted His vineyard and what He expected it to produce. We then move to the Epistle, Philippians 3:4b–14, to see how the apostolic Church received and applied the Gospel’s teaching that all human righteousness is loss compared to the surpassing worth of knowing Christ. We close with a prayer that gathers up everything the texts have taught us.

The Collect of the Day

Gracious God, You gave Your Son into the hands of sinful men who killed Him. Forgive us when we reject Your unfailing love, and grant us the fullness of Your salvation; through Jesus Christ, Your Son, our Lord, who lives and reigns with You and the Holy Spirit, one God, now and forever. Amen.

Question 1

What is this prayer’s central petition, and what does it lead you to expect from today’s readings? Notice that the Collect names a specific historical act: God “gave Your Son into the hands of sinful men who killed Him.” The prayer then asks God to “forgive us when we reject Your unfailing love.” If the Collect confesses that God’s own Son was handed over to death and that we ourselves are among those who reject His love, what themes of judgment and mercy might the readings that follow explore?

The Gospel Reading — Matthew 21:33–46

✛ Read aloud: Matthew 21:33–46

Matthew 21:33–46, the Parable of the Wicked Tenants, appears as an alternate Gospel in the One-Year lectionary on the Twentieth Sunday after Trinity, yet in that setting it is paired with Isaiah 55:1–9 and Ephesians 5:15–21, readings that do not develop the vineyard imagery. Series A pairs this parable with Isaiah 5:1–7, the original “Song of the Vineyard” that Jesus is deliberately echoing, and with Philippians 3:4b–14, Paul’s radical rejection of his own religious credentials. Reading the Isaiah source text alongside the Matthean parable allows the congregation to see how Jesus claims the vineyard imagery for Himself and pronounces judgment on those who refuse to render God His due.
Question 2

Jesus tells this parable in the temple courts during Holy Week, directly confronting the chief priests and Pharisees. He opens by describing a master who “planted a vineyard and put a fence around it and dug a winepress in it and built a tower” (v. 33). Every detail in this description is drawn from Isaiah 5:1–2, where Yahweh plants a vineyard for Israel. Read Isaiah 5:1–2. In Isaiah’s original, the vineyard (Israel) fails to produce good fruit. In Jesus’ parable, however, the problem is not the vineyard itself; it is the tenant farmers. What is Jesus changing about Isaiah’s original accusation, and what does this shift reveal about whom He is confronting?

Question 3

The owner sends “his servants” (doulous) to collect the fruit at harvest time (v. 34). These servants represent the Old Testament prophets whom God sent to Israel over the centuries. Read 2 Chronicles 36:15–16, which summarizes Israel’s treatment of the prophets. How does the pattern of sending and rejection described in Chronicles illuminate the parable’s portrait of the tenants who beat, kill, and stone the owner’s servants (vv. 35–36)?

Question 4

After the servants are killed, the owner says, “They will respect my son” (v. 37). The tenants, however, conspire: “This is the heir. Come, let us kill him and have his inheritance” (v. 38). The desire to seize the inheritance reveals the fundamental sin at work. The tenants want the fruit of the vineyard without submitting to the authority of the owner. In what ways does this mirror the religious leaders’ relationship to the kingdom of God: claiming its authority as their own while refusing to yield its fruit to the God to whom it belongs?

Question 5

The tenants “threw him out of the vineyard and killed him” (v. 39). Note the sequence: the son is cast out first, then killed. This detail foreshadows the historical reality of Christ’s crucifixion, in which Jesus was led outside the walls of Jerusalem to die at Golgotha. Read Hebrews 13:12: “Jesus also suffered outside the gate in order to sanctify the people through his own blood.” How does this connection between the parable and the Passion shape your reading of the tenants’ actions?

Question 6

Jesus asks the religious leaders what the owner will do to the wicked tenants (v. 40). They answer: “He will put those wretches to a miserable death” (v. 41). The Greek phrase kakous kakos apolesei involves a striking wordplay: “he will dreadfully destroy those dreadful men.” The leaders have unwittingly pronounced their own sentence. What does this moment of self-condemnation reveal about the blinding power of sin, where those most confident in their own righteousness fail to recognize themselves in the parable of judgment?

Question 7

Jesus immediately shifts the metaphor from agriculture to architecture by quoting Psalm 118:22–23: “The stone that the builders rejected has become the cornerstone” (v. 42). The “builders” are the religious leaders who reject and kill the Son. The Greek word for “cornerstone” (kephalen gonias) refers to the capstone or chief foundation stone. Read Acts 4:11, where Peter applies this same Psalm to the risen Christ. If the “builders” killed the Son, how does the Son becoming the cornerstone point to the Father’s vindication through the resurrection?

Question 8

In verse 43, Jesus declares, “The kingdom of God will be taken away from you and given to a people (ethnei) producing its fruits.” The Greek word ethnos here does not refer to a single ethnic group; it points forward to the new people of God, the Church, comprised of both Jews and Gentiles. The full phrase is ethnei poiounti tous karpous (“a people producing its fruits”). The kingdom is not destroyed; it is transferred. What does this transfer reveal about God’s response to the rejection of His Son: does He abandon His vineyard, or does He entrust it to new stewards?

Question 9

Verse 44 warns that anyone who falls on this stone “will be broken to pieces” (synthlasthesetai), and that anyone on whom it falls “will be crushed” (likmesei, literally “winnowed” like chaff). The cornerstone is both the foundation of salvation and the instrument of judgment. How does this dual function of the stone capture the Law/Gospel dynamic at the heart of the text: the same Christ who is the Church’s foundation becomes the crushing weight of judgment for those who reject Him?

Question 10

The chief priests and Pharisees “perceived that he was speaking about them” (v. 45), yet they do not repent. Instead, “they were seeking to arrest him” (v. 46). They understand the parable perfectly, yet understanding does not produce faith. Their hostility only increases. What does this response illustrate about the difference between intellectual comprehension of the Gospel and the faith that receives it? What prevents mere understanding from becoming saving trust?

The Old Testament Reading — Isaiah 5:1–7

✛ Read aloud: Isaiah 5:1–7

This reading was chosen to prepare for the Gospel. Isaiah 5:1–7 is the original “Song of the Vineyard” upon which Jesus deliberately builds His parable in Matthew 21. In Isaiah, God Himself is the vineyard owner who did everything necessary for His people to flourish, yet the vineyard produced only worthless fruit. Series A pairs these two passages so that the congregation can hear the source text alongside its New Testament fulfillment.
Question 11

Isaiah begins as a minstrel singing a love song about “my beloved” (v. 1). The Hebrew word for “beloved” is dod, a root that forms a deliberate pun on the name “David” (Dawid). Isaiah hints from the first line that this song concerns God’s relationship with the Davidic monarchy and its people. The vineyard is planted on a “very fertile hill,” literally a “horn, a son of oil” in Hebrew, evoking the imagery of royal anointing. What does this language of beloved king and anointed hilltop suggest about the identity and vocation of the vineyard?

Question 12

The owner does everything right for the vineyard: clearing stones, planting choice vines, building a watchtower, and hewing a winepress (v. 2). He then expects “grapes” (’anabim), yet the vineyard yields be’ushim (v. 2). Most English Bibles translate this as “wild grapes,” yet the Hebrew root literally means “to stink.” The fruit may have looked like grapes outwardly, yet inwardly it was rotten and produced a stench before God. How does this image of fruit that appears legitimate yet smells of decay illustrate the hypocrisy that Jesus exposes in the religious leaders of Matthew 21?

Question 13

Isaiah 5:7 contains what many scholars consider the most brilliant wordplay in the Old Testament. God expected mishpat (justice) and found mispach (bloodshed); He expected ts’daqah (righteousness) and heard tse’aqah (a cry of distress). The Hebrew words in each pair differ by only a single consonant, so the ear barely catches the difference. The implication is devastating: Israel’s counterfeit religion sounded holy, yet it produced only injustice and the cries of the oppressed. How do these nearly identical sounds with radically different meanings capture the nature of religious hypocrisy?

Question 14

In Isaiah 5, the problem is the vineyard itself: it fails to produce good fruit, and God responds by removing its hedge, breaking down its wall, and withholding His rain (vv. 5–6). In Matthew 21, the vineyard is not destroyed; the tenants are removed and the vineyard is given to others. Read John 15:1, where Jesus declares, “I am the true vine.” If Israel’s vineyard failed to produce the justice and righteousness God required, and if Jesus claims to be the true vine, how does Christ’s person and work solve the crisis that Isaiah 5 exposes?

The Epistle Reading — Philippians 3:4b–14

✛ Read aloud: Philippians 3:4b–14

The Epistle shows how the apostolic Church received and applied the Gospel’s teaching. In Philippians 3, Paul demonstrates that even the most impressive human credentials, the very “fruit” of religious striving, are worthless refuse compared to the alien righteousness of Christ received by faith. The tenants of Matthew 21 grasped for the inheritance by their own power; Paul confesses that he discarded his own “inheritance” to gain Christ.
Question 15

Paul catalogs his religious credentials: circumcised on the eighth day, of the tribe of Benjamin, a Hebrew of Hebrews, a Pharisee, a persecutor of the Church, and “as to righteousness under the law, blameless” (amemptos, vv. 5–6). In the parable, the tenants claimed the vineyard’s fruit as their own possession. How does Paul’s former confidence in his religious pedigree mirror the tenants’ refusal to render the vineyard’s produce to its rightful owner?

Question 16

Paul declares that he counts all his former “gain” as “loss” (zemia) and even as “rubbish” (skubala, v. 8). The Greek word skubala is coarse and blunt, referring to human waste or worthless refuse. Paul is not merely ranking Christ higher than the Law; he is categorizing his entire former religious identity as excrement in comparison to “the surpassing worth of knowing Christ Jesus my Lord.” How does Paul’s radical revaluation of his own righteousness echo Isaiah 5’s portrait of fruit that appeared legitimate yet was rotten before God?

Question 17

In verse 9, Paul states his desire to be “found in him, not having a righteousness of my own (emen dikaiosynen) that comes from the law, but that which comes through faith in Christ (dia pisteos Christou), the righteousness from God that depends on faith.” Paul here contrasts two entirely different systems of justification. The first is a righteousness directed from the human toward God; the second is a righteousness that God declares and credits to the sinner through faith. How does this distinction between self-generated righteousness and alien righteousness illumine the crisis in both Isaiah 5 and Matthew 21, where human effort fails to produce what God demands?

Question 18

Paul writes, “Not that I have already obtained this or am already perfect, but I press on to make it my own, because Christ Jesus has made me his own” (v. 12). The Greek verb katalambano (“to seize, to take hold of”) is used twice: Paul presses on to take hold of the prize, yet he does so only because Christ first “took hold of” him. Paul’s pursuit of spiritual maturity is not the cause of his salvation; it is the result. How does this statement of divine monergism (God acting first and alone) connect to the parable’s declaration that the kingdom is “given” to a new people (Matthew 21:43), not earned or seized?

Theological Synthesis

Question 19

All three readings expose the utter bankruptcy of human righteousness and the sufficiency of God’s grace. Isaiah’s vineyard produces only the stench of counterfeit fruit. The tenants in Matthew 21 murder the heir to seize the inheritance. Paul’s impeccable religious credentials prove to be worthless refuse. Yet in each text, God does not abandon His purpose. He sends His Son, and even when the Son is killed, God raises Him as the cornerstone of a new temple. Consider the Second Article of the Apostles’ Creed: “I believe in Jesus Christ, His only Son, our Lord, who… suffered under Pontius Pilate, was crucified, died and was buried… The third day He rose again from the dead.” How do all three readings together illuminate this confession that the Son was given over to death yet vindicated by the Father through the resurrection?

Question 20

Our congregation hears an overlapping portion of Matthew 21:33–44 as an alternate Gospel on the Twentieth Sunday after Trinity, yet the One-Year never pairs it with Isaiah 5:1–7 or Philippians 3:4b–14. Having studied these three readings together, what has been missing from your understanding of the vineyard theme? How does hearing the Isaiah source text alongside the parable change the way you read Jesus’ words? How does Paul’s confession that all human righteousness is skubala deepen your grasp of why the kingdom must be received as a gift rather than seized as an inheritance?

Question 21

In the Lord’s Supper, Christ gives His people the fruit of the vineyard: His own body and blood under the bread and wine. Jesus declared, “I am the true vine” (John 15:1), and on the night of His betrayal He took the cup and said, “This is my blood of the covenant, poured out for many for the forgiveness of sins” (Matthew 26:28). The tenants of the parable refused to render fruit to the owner; in the Sacrament, the Owner Himself gives the fruit to His people. How does the Lord’s Supper reverse the crisis of the vineyard by making Christ’s own righteousness the fruit that we receive rather than the fruit that we must produce?

Liturgical Connections

Sacramental connections

The readings for this day connect to the Lord’s Supper through the vineyard and cup imagery that runs from Isaiah 5 through Matthew 21 and into the Words of Institution. Isaiah’s vineyard, which failed to produce the wine of justice and righteousness, finds its fulfillment in the true vine, Jesus Christ, who offers His own blood in the cup of the New Testament for the forgiveness of sins. The Parable of the Wicked Tenants also connects to the liturgy of Good Friday: verses from Isaiah 5:2–4 are employed in the Reproaches (Improperia) during the Chief Service on Good Friday, where the voice of God confronts the Church: “What more could have been done for My vineyard than I have done for it?” In Philippians 3:9, Paul’s confession of the alien righteousness received through faith corresponds to the baptismal pattern of dying and rising with Christ: the old “fruit” of self-righteousness is buried, and the new righteousness of Christ is put on.

Typological and Old Testament connections

Isaiah 5:1–7 is the direct Old Testament source for the Parable of the Wicked Tenants in Matthew 21:33–46. Jesus reproduces the vineyard’s details (fence, winepress, tower) from Isaiah’s song and then redirects the accusation from the vineyard’s failed fruit to the tenants’ violent rebellion. The rejected cornerstone of Psalm 118:22–23, quoted by Jesus in Matthew 21:42, is applied to the risen Christ in Acts 4:11 and 1 Peter 2:7. Isaiah’s 240-syllable poem of vineyard failure (Isaiah 5:1–7) is structurally matched by the 240-syllable poem of messianic hope in Isaiah 9:1–7, where a new Davidic king will establish mishpat and ts’daqah forever. Jesus’ declaration “I am the true vine” (John 15:1) brings the vineyard imagery to its ultimate christological fulfillment.

Hymn selections

LSB 680Thine the Amen, Thine the Praise. This eucharistic and eschatological hymn draws on the vineyard and cup imagery of Isaiah 5, celebrating the feast that God prepares for His people in the Sacrament of the Altar.
LSB 547The Tree of Life. Stanza 3 of this hymn reflects the Parable of the Wicked Tenants, proclaiming Christ’s solidarity with the fallen world and His fulfillment of the Law that we could not keep.
LSB 667Saints, See the Cloud of Witnesses. Grounded in Paul’s athletic metaphor from Philippians 3:13–14 (forgetting what lies behind and straining forward to the prize), this hymn summons Christians to run the race of their baptismal life with their eyes fixed on Jesus.
LSB 686Come, Thou Fount of Every Blessing. This hymn echoes Philippians 3:8 in confessing that all earthly gain is loss compared to the surpassing worth of knowing Christ, and it celebrates the unmerited grace by which God binds His wandering people to Himself.

Closing Prayer

O Lord Jesus Christ, the beloved Son whom the Father sent into the vineyard of this fallen world, and whom sinful men cast out and killed: You were the stone that the builders rejected, yet the Father raised You from the dead and made You the cornerstone of His eternal kingdom. Grant that we, who have heard Your Word in these holy Scriptures, may never trust in the stinking fruit of our own righteousness, but may count all things as loss for the surpassing worth of knowing You; clothe us in the alien righteousness that comes through faith alone, feed us with the fruit of Your own body and blood in the Holy Supper, and by Your Spirit make us a people who produce the fruits of justice and mercy, not to earn our inheritance, but in joyful thanksgiving for the kingdom You have freely given; for You live and reign with the Father and the Holy Spirit, one God, now and forever. Amen.
