The Third Sunday after Trinity

The Seeking Grace of God

One-year lectionary  ·  Micah 7:18–20  ·  1 Peter 5:6–11  ·  Luke 15:1–10

The Third Sunday after Trinity carries a deeply penitential and comforting focus, emphasizing God’s relentless mercy toward sinners. The Introit from Psalm 25 sets the tone: “Turn to me and be gracious to me, for I am lonely and afflicted; forgive all my sins.” The appointed Gospel, the parables of the lost sheep and the lost coin, has shaped this Sunday’s hymnody with particular richness: Erdmann Neumeister composed “Jesus Sinners Doth Receive” to close his 1718 sermon on this Gospel, calling it the “sweet kernel of the powerful Gospel” against the Pietists of his day.

The shape of the service

Trinity I–V: The Call to the Kingdom of Grace

The first cycle of Trinitytide focuses on God’s gracious invitation to His kingdom. Where Advent through Pentecost proclaimed what God has done in the history of salvation, these Sundays apply that salvation to the life of the Church: who is invited, on what basis, and how that invitation is received or refused. The readings across this cycle move from the foundational doctrine of justification by faith (Trinity I, Genesis 15) through the great banquet of grace (Trinity II, Luke 14), and now to the seeking, finding mercy of God (Trinity III, Luke 15).

The appointed hymnody for these Sundays is unusually rich. Olearius, Franck, and Rist all wrote specifically for this Gospel cycle, reflecting the Reformation conviction that the Church’s song must match the contours of the lectionary. The Collect for this Sunday addresses God as “the protector of all who trust in You,” asking Him to multiply His mercy so that we may pass through temporal things without losing the things eternal.

The readings at a glance

Old Testament
Micah 7:18–20

Micah’s own name, miy-’el kamokha, “Who is a God like you?” becomes the rhetorical question that closes his entire book. Pagan gods were praised for their power to destroy; Yahweh’s incomparability lies in His delight in mercy. He is a God who nose’ ’awon, who “bears iniquity,” the verb nasa’ meaning to physically carry a burden. It anticipates Isaiah 53’s Suffering Servant, who would bear the iniquity of us all. He chaphetz, delights, in chesed, His loyal, unmerited covenant love.

In verse 19 Micah shifts to direct address: “You will cast into the depths of the sea (metsulot yam) all their sins.” The phrase echoes Exodus 15, where Pharaoh’s army sank into those same depths, metsolot. The forgiveness of sins is the New and Greater Exodus: God drowns our sins as decisively as He drowned the Egyptian army. The passage closes by anchoring grace in the ancient oath to Abraham and Jacob, the promise of a Seed to bless all nations, binding God’s present mercy to His eternal covenant word.

Epistle
1 Peter 5:6–11

Peter balances the terror of spiritual warfare with the comfort of the Father’s care. Believers humble themselves under God’s “mighty hand,” a rich Old Testament idiom for sovereign power, casting every anxiety on Him “because he cares for you.” Then Peter names the enemy with surgical Greek precision. The antidikos is the legal adversary, the prosecuting attorney in the heavenly courtroom. The diabolos comes from dia and ballō, “to hurl,” the slanderer who hurls false accusations before God. He prowls like a lion, and Peter’s audience felt this literally: under Nero, some Christians were fed to lions in the arena.

Luther described the devil’s strategy in the Large Catechism: he “tries every trick and does not stop until he finally wears us out, so that we either renounce our faith or throw up our hands.” The defense is not human reason but firm faith in the Word, joined to the knowledge that the entire worldwide brotherhood shares this same suffering. The passage closes with four verbs of divine promise: God will restore, confirm, strengthen, and stērizō, establish firmly, His people after “a little while.” The brevity of suffering and the eternity of glory are held in deliberate contrast.

Holy Gospel
Luke 15:1–10

Tax collectors and sinners press in to hear Jesus; the Pharisees grumble that “this man welcomes sinners and eats with them.” Table fellowship in the first century was intimate acceptance, not mere hospitality. Jesus aims His parables directly at the grumblers. The shepherd leaves ninety-nine in the erēmō, the open country, and carries the found sheep home on his shoulders. The sheep does nothing. The rescue is pure monergism: every verb of seeking and finding belongs to the shepherd alone.

The woman lights a lychnon (lamp) and sweeps the dark Palestinian house to find one drachmē, a day’s wage and likely part of her dowry headdress, her only security. A coin is inanimate: it cannot bleat, repent, or find its own way back, underscoring our complete spiritual inability apart from God’s seeking grace. Both searches end in a synkaleō, a formal celebration summoning the whole community, and the joy “before the angels of God” is a Jewish circumlocution for God Himself rejoicing in His court. The “ninety-nine who need no repentance” is biting irony: before the Gospel finds us, the Law must first show us that we are lost.

The hymns and their stories

Opening Hymn
“O God, O Lord of Heaven and Earth”  ·  LSB 834
Martin H. Franzmann (1907–76) wrote this hymn on commission to mark the 450th anniversary of the Reformation in 1967, its assigned theme being “Life: New Life.” It was first published in the Pentecost 1967 issue of Response in Worship, Music, the Arts. Franzmann’s original manuscripts survive at the Concordia Historical Institute in St. Louis; alongside the fair copy dated September 23, 1966, is a rough draft where he scribbled potential end rhymes in the margin, a rare glimpse of a great hymn writer at work. One small editorial change was made when the text was included in the 1969 Worship Supplement: the word “strangles” in the third stanza was moved to the past tense “strangled.” The powerful tune WITTENBERG NEW was composed by Jan O. Bender (1909–1994), then on the music faculty at Wittenberg University in Springfield, Ohio, and its original publication included parts for congregation, organ, and trumpet descant.
Hymn of the Day
“Lord, to You I Make Confession”  ·  LSB 608
Johann Franck (1618–77), the same lawyer-poet who gave us “Soul, Adorn Yourself with Gladness,” published this text in eight stanzas in Johann Crüger’s 1648 hymnal under the heading “for the forgiveness of sins.” His original German title, Herr, ich habe missgehandelt, means simply “Lord, I have misbehaved,” a posture of almost childlike humility before God. Modern hymnals made one important theological correction to Catherine Winkworth’s 1863 translation: her phrase “forced at last to see my errors” was changed to “led by You to see my errors,” clarifying that true contrition is worked by Christ, not compelled against the will. The most striking detail lost in translation is in the third stanza, where Franck’s German addresses Christ with visceral imagery: “but Christ, Your sores, yes, even a single drop of Your blood, can heal my wounds,” a sacramental connection to the blood poured out on Calvary and given in the Supper.
Distribution Hymn
“O Lord, We Praise Thee”  ·  LSB 617
Called the “Lutheran Communion hymn par excellence,” this text began as a one-stanza Leise in the late fourteenth century, traced to manuscript evidence at the Cistercian convents of Medingen and St. Maria Magdalena near Lüneburg. Around 1524, Luther expanded it with two new stanzas of Eucharistic theology and in his 1526 German Mass listed it as one of three ideal hymns for singing during the distribution of the body and blood of Christ. Its popularity was staggering: it was prescribed in more German Lutheran church orders than any hymn except Luther’s creedal paraphrase “We All Believe in One True God.” The ultimate testament to its power is that the Roman Catholic author Johann Leisentritt included it in his 1567 Catholic hymnal Geistliche Lieder und Psalmen, with Luther’s Protestant text intact. The tune is an anonymous fifteenth-century cantio that musicologists have traced to Thomas Aquinas’s great Corpus Christi sequence Lauda Sion salvatorem.
Closing Hymn
“Lord Jesus Christ, with Us Abide”  ·  LSB 585
This hymn weaves together contributions from three major Reformation figures. Its first stanza may trace to a 1551 Latin verse by Philipp Melanchthon: “Now comes the evening; stay with us, O Christ; do not allow Your light to be extinguished.” Nicolaus Selnecker expanded the text to seven stanzas in 1572 and nine in 1611 to thank God for preserving His Church and its preaching. The second stanza appeared in 1602 in a booklet of prayers written for the schoolchildren of Freiberg to sing against a threatened Ottoman invasion. The English text combines Catherine Winkworth’s beloved opening lines with F. Samuel Janzow’s 1982 translation, and Lutheran Service Book editors sharpened the fourth stanza from “bright lance” to “bright sword of Your mighty Word.” The hymn is anchored in the Emmaus road: “Stay with us, for it is toward evening” (Luke 24:29), applying that plea to the twilight of the age, and answering it in the final stanza: Christ abides through “Your Word alone our heart’s defense.”
