The Sixth Sunday after Trinity

The Better Righteousness

One-year lectionary · Exodus 20:1–17 · Romans 6:1–11 · Matthew 5:17–26

The Sixth Sunday after Trinity brings together three of the most foundational biblical texts in the catechetical tradition: the Ten Commandments from Sinai, Paul’s baptismal theology in Romans 6, and the Sermon on the Mount. The day’s Collect asks God to “graft into our hearts the love of Your name, increase in us true religion, nourish us with all goodness.” The paired petitions of that prayer mirror the paired movement of the service itself: from the Law’s demand to the Gospel’s gift. The Old Testament reading presents the “Ten Words” as God’s gracious charter for His redeemed people, delivered after the Exodus, not before. The Gospel then reveals that Jesus came not to abolish but to fulfill these Words, driving their demand inward to the heart — where only His righteousness can satisfy.

The shape of the service

Introit. Psalm 28 declares, “The Lord is the strength of his people; he is the saving refuge of his anointed. Save your people and bless your heritage!”

Collect. Petitions God to graft love of His name into our hearts, increase true religion, and nourish us with all goodness — four paired gifts of grace flowing entirely from His mercy.

Gradual. Psalm 90 pleads, “Return, O Lord! Have pity on your servants! From everlasting to everlasting you are God.”

Sacrament. The Service of the Sacrament uses the Common Proper Preface. The liturgical color is green. Those who have been baptized into Christ’s death receive at His table the life His resurrection won.

The readings at a glance

Old Testament

Exodus 20:1–17

Before a single command is given, Yahweh states His credentials in pure Gospel: “I am Yahweh your God, who brought you out of the land of Egypt, out of the house of slavery.” Deliverance precedes demand. The text the Church receives here is never actually called “commandments” in Hebrew; Scripture calls them the ’asereth haddebarim, the “Ten Words,” rendered in the Greek Septuagint as deca logous, the source of our word “Decalogue.”

Structurally, the negative commands use not the imperative mood but the negative particle lo’ paired with the imperfect tense, making them indicative statements: “you will not murder.” They describe the contours of life in God’s kingdom, not a ladder to climb into it. Two words reward closer attention: kabad (the Fourth Word’s verb for “honor,” literally “to treat as heavy”), and chamad (the Tenth Word’s “coveting”), which reaches past every outward court into the hidden jurisdiction of the heart.

Epistle

Romans 6:1–11

Paul answers the charge that grace licenses sin with four spectacular compound Greek words built on the prefix syn (“with”): synetaphemen (“we were buried with”), symphytoi (“grown together with,” a perfect tense marking a permanent present reality), synestaurothen (“our old man was crucified with”), and syzesomen (“we will live with”). In every case the verb is passive: God acted; we were acted upon. Baptism is not a human work offered to God but God’s own burial and raising of the sinner.

The climax arrives in verse 7 with the word dedikaiotai, which English translations typically render as “freed from sin,” but which is in fact the perfect passive of dikaioo — the exact verb for “justified.” The one who died with Christ stands legally acquitted before God’s bench. Paul therefore issues his first imperative in six chapters: logizesthe, “count yourselves” — an accounting term. Because God has credited you as dead to sin and alive to Christ, you must calculate your life by His ledger.

Holy Gospel

Matthew 5:17–26

Jesus opens with a threshold claim: His disciples’ dikaiosyne (righteousness, conduct flowing from a transformed heart) must exceed that of the scribes and Pharisees, whose error was not ignorance but hypocrisy — knowing the right and doing otherwise. He then interprets the Fifth Commandment with a triadic formula, each clause introduced by His own authority: ego de lego hymin, “But I myself am saying to you.” Harboring anger, calling a brother “raca” (the Aramaic reqa’, “empty-head”), or “more” (fool) makes one liable to gehenna, the Valley of Hinnom south of Jerusalem where apostate Israel once burned children and which had become the supreme image of final judgment.

The remedy is urgent: if you remember at the altar that a brother has something against you, leave the gift and go. The verb diallagethi (“be reconciled”) appears nowhere else in the New Testament. Those who refuse to settle the account face a prison with no release, for the debt is infinite and only Christ can pay it.

The hymns and their stories

Opening Hymn

“Baptismal Waters Cover Me” · LSB 616

This hymn was written by Canadian Lutheran pastor Kurt Reinhardt out of a deeply personal encounter with private confession. In his final year of seminary, feeling the weight of unconfessed sin before his ordination, Reinhardt found he could only unburden himself by clinging to his Baptism and trusting God as Father on account of Christ. As the pastor spoke Christ’s words of absolution, Reinhardt understood that this forgiveness was a direct return to his baptismal font in Ottawa some thirty years earlier. He had no idea the text had been submitted to the Lutheran Service Book committee; he only learned of its inclusion when notified of its acceptance. The text is warmly personal, yet its true focus rests entirely on Christ’s work delivered through Baptism and Absolution, ending with the font as the Father’s sacramental embrace that places the sinner safely into Christ’s hands.

Hymn of the Day

“In Adam We Have All Been One” · LSB 569

Martin Franzmann (1907–1976) wrote this text whose origins trace to a 1949 free conference between American and German Lutherans at Bad Boll, an event that left a deep impression on him. The earliest known manuscript, from 1962, was literally assembled by pasting the music onto the backs of letters and an order of service from the Lutheran Laymen’s League — a detail that captures the ad hoc urgency of its composition. It was likely written for a hymn contest at the 1962 Missouri Synod convention and published the following year. The hymn swept beyond Lutheran circles, appearing in Anglican and Methodist hymnbooks in Britain after being sung at the 1977 Hymn Society of Great Britain conference. It even inspired a 1986 Swedish paraphrase set to a traditional folk tune. Its theology is sweeping: all humanity is pictured as “one huge rebellious man” until the Good Shepherd seeks, suffers, and sets the lost free with His truth.

Hymn

“Now, My Tongue, the Mystery Telling” · LSB 630

Thomas Aquinas wrote this office hymn around 1263 for the newly established feast of Corpus Christi. He modeled it deliberately on Venantius Fortunatus’s sixth-century “Sing, My Tongue, the Glorious Battle” (LSB 454), borrowing the exact same opening Latin words, Pange lingua gloriosi, and the same meter — so the two hymns share a tune. The first stanza and third stanza draw on imagery Aquinas quoted in the Summa Theologiae from an even older ancient hymn, giving the text roots that reach back centuries before him. By the sixteenth century, the Corpus Christi festival had accumulated enough medieval excess that Luther condemned it, and Lutherans moved commemoration of the Lord’s Supper to Maundy Thursday. The English translation relies heavily on Edward Caswall’s 1849 version, made the very year he converted from Anglicanism to Catholicism, supplemented by John Mason Neale’s 1851 rendering.

Closing Hymn

“My Hope Is Built on Nothing Less” · LSB 575

Edward Mote (1797–1874) wrote this text in 1825, the day he heard news of the Ogle Castle shipwreck on the Goodwin Sands, a notorious ten-mile sandbank in the English Channel. The entire crew of over a hundred men was lost when rescue boats could not reach them. That disaster drove the hymn’s nautical imagery: the “sinking sand,” the “rough and stormy gale,” the “anchor holds,” the “sinking flood.” Mote completed the chorus and four stanzas in a single day, then brought the new text to a parishioner’s sick-bed the following week when her husband could not find the hymnbook. She enjoyed it so much that Mote added two more stanzas, printed a thousand copies, and submitted the text anonymously to The Spiritual Magazine. One historical detail tends to surprise singers: the familiar opening line “My hope is built on nothing less” was not Mote’s original first line; the hymn originally began, “Nor earth nor hell my soul can move, I rest upon unchanging love.”
