St. Luke, Evangelist

Observed · The Beloved Physician and the Medicine of the Gospel

One-year lectionary · Isaiah 35:5–8 · 2 Timothy 4:5–18 · Luke 10:1–9

Almost everything the Church knows about Luke comes from three verses of St. Paul, and the Fathers guarded them closely. Eusebius records that he was “by race an Antiochian and by profession a physician,” long a companion of Paul; Jerome calls him a Syrian of Antioch, not unskilled in Greek, who wrote his Gospel from what eyewitnesses delivered but composed the Acts of the Apostles “as he himself had seen,” which is why that book slips into “we.” Rufinus put it best: keeping to the medicine he had received from the apostles, Luke “composed for us two books of remedies for the healing of souls rather than bodies.” Jerome adds that his bones were carried to Constantinople with those of St. Andrew about the year 356. October 18 comes down to us from the ancient martyrologies, and the color is red.

The shape of the service

A Feast of Christ. The days of the apostles and evangelists are kept with the full Divine Service, because the lives of these men are so bound to our Lord’s own that their stories belong to the Gospel itself. Apology XXI gives three reasons to remember the saints: thanksgiving, the strengthening of faith, and the imitation of their faith and works in our own callings.

The Propers. Are the older common of Evangelists: the Gradual of Psalm 45, “Thou art fairer than the children of men,” and the Verse from Ephesians 4, “The Lord Jesus gave some, Apostles, and some, Evangelists, for the edifying of the body of Christ.” The newer Introit sets Psalm 92 under the Emmaus antiphon of Luke 24, that repentance and forgiveness be proclaimed to all nations.

The Collect. Names the theme of the whole day: God called Luke the physician to be an evangelist and physician of the soul, and we ask that the healing medicine of the Gospel and the Sacraments put to flight the diseases of our souls.

Color. Red, as for the apostles and evangelists.

The readings at a glance

Old Testament

Isaiah 35:5–8

The chapter is the bright climax after the darkness of Isaiah 34, and it opens with ’az, “then,” the adverb Isaiah uses for the moment God breaks into history. Both verbs in verse 5 are Niphal passives, tippaqachnah and tippatachnah: eyes that were sealed are popped open and ears unstopped, and the passive is deliberate, since no one unseals his own. It reverses the judicial sentence of Isaiah 6, where the prophet was sent to make ears heavy and seal eyes shut. Then the lame man does not merely walk; yedalleg is to leap and vault, ka’ayyal, like a stag.

Two words carry this text straight into Luke’s own writing. The Greek translators rendered “the tongue of the mute” with the rare word mogilalos, which appears in the New Testament only in Mark 7, where our Lord says “Ephphatha” to a deaf man with a tied tongue. And when the lame beggar at the Beautiful Gate stands up in Acts 3, Luke writes that he went into the temple “walking and leaping,” hallomenos, the exact verb of the Greek Isaiah. Then the desert mirage becomes a real pool, and a highway appears: the Way of Holiness, which is what the Church is first called in Luke’s second book.

Epistle

2 Timothy 4:5–18

This is Paul’s last will, written from a Roman cell under Nero with the sword in view. He is being poured out, spendomai, the verb for the drink offering emptied at the base of the altar over a sacrifice already slain; his death is not a defeat but the last cup of a liturgy. The time of his analysis has come, a word that means at once unmooring a ship, striking a tent, and unyoking an ox. Three perfect tenses follow: the noble contest fought, the marked-out course finished, the faith guarded. What waits is a stephanos, not the diadem of a king but the victor’s wreath, promised to all who have loved His appearing.

Then the room empties. Demas “loved the present age,” the deliberate opposite of loving that appearing, and left. Crescens and Titus are deployed elsewhere. “Luke alone is with me.” Mark, once refused as a deserter, is now euchrestos, useful, the very word Paul uses of the runaway slave Onesimus. Bring the cloak, and the books, above all the parchments. At the first hearing no one appeared for him, and he prays that it not be reckoned to them, using the accounting verb of Romans 4. No man stood by him; the Lord stood by him.

Holy Gospel

Luke 10:1–9

Only Luke records this sending, and it stands at the head of the long journey to Jerusalem. The verb anedeixen is a public installation into office, used elsewhere in the New Testament only when Matthias is chosen. The manuscripts divide between seventy and seventy-two, and both numbers preach: seventy for the elders Moses appointed to bear the people, seventy-two for the nations of the world in the Greek Genesis, a number a Gentile evangelist would notice. They go two by two, the number of witnesses required by the Law, and “before His face,” as heralds of one who is coming behind them.

Pray the Lord of the harvest to thrust out laborers: ekbale is a strong verb, not a gentle sending. They go as lambs among wolves, and arnas is not the ordinary word for sheep but the sacrificial lamb of the Passover, so the mission is cruciform from the start. No purse, no bag, no sandals, and no greetings on the road, the same urgency Elisha laid on Gehazi. Their first word in any house is peace, and that peace is no pleasantry but a gift that rests on a man or returns unspent. Then: heal the sick, and tell them the kingdom of God has come near.

The hymns and their stories

Opening Hymn

“Praise the Almighty, My Soul, Adore Him” · LSB 797

Most hymns built on a psalm take a verse or two and leave the rest. Johann Daniel Herrnschmidt (1675–1723) took all of Psalm 146. He was a professor of theology and vice-director of the Halle Foundations, the orphanage and schools at the heart of German Pietism, and his eight German stanzas work in nearly every idea the psalmist wrote. Pietist though he was, he did not miss why the psalm was written: Christ and His atoning work stand behind the line “pardon and peace from Him obtain.” On the day the Church remembers the beloved physician, it is worth noticing which psalm this is, the one that praises the God who heals all diseases and lifts up those bowed down.

Hymn of the Day

“Lord, Thee I Love with All My Heart” · LSB 708

Martin Schalling (1532–1608) paid for his convictions more than once. Sent to Regensburg in 1554 after his years at Wittenberg, this peaceable pastor had to choose between opposing the Flacian heresy and keeping his living; he chose the confession and was made to leave the city. Given refuge by Count Richard of the Palatinate, he preached the Easter Vespers sermon in the count’s residence in 1569, on Exodus 12 and the Passover lamb, and the manuscript survives with this hymn copied out in his own hand directly after the sermon, headed simply “Gebett,” a prayer. Bach made the third stanza the closing chorus of the St. John Passion, the very stanza appointed for the Commendation of the Dying, which suits this day exactly: it asks the physician of the soul for the one cure no other physician has.

Hymn before Communion

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

The Latin, Pange lingua gloriosi, corporis mysterium, was almost certainly written by Thomas Aquinas (ca. 1225–74) as an Office hymn for the new festival of Corpus Christi, added to the Roman calendar in 1264. Luther later condemned that festival outright, and Lutherans keep the institution of the Sacrament on Maundy Thursday instead, so the text required careful handling to confess Christ’s true presence without the medieval dogma attached to it. Aquinas borrowed his opening words and his meter from Venantius Fortunatus’s sixth-century battle hymn “Sing, My Tongue, the Glorious Battle” (LSB 454), so ours can still be sung to that older tune.

Closing Hymn

“Evening and Morning” · LSB 726

Paul Gerhardt (1607–76) is the greatest German hymn writer of his century, and the hard years of the Thirty Years’ War gave him more to draw on than any poet would choose. The hymn appeared in 1666 in the third part of Johann Georg Ebeling’s edition of Gerhardt’s spiritual songs, with a tune by Ebeling himself, who had succeeded Johann Crüger at St. Nicholas Church in Berlin. The German begins “Die güldne Sonne,” the golden sun, and runs to twelve stanzas. Richard Massie’s 1857 translation kept the theology intact where several Victorian translators flattened it, and he began not at the top but at Gerhardt’s fourth stanza, “Abend und Morgen,” which is why the hymn is called “Evening and Morning” in English at all.
