St. Luke the Evangelist: Reference Guide

A structured reference guide to the Holy Apostle and Evangelist Luke — the physician of Antioch, companion of the Apostle Paul, author of the third Gospel and the Acts of the Apostles, and, in later Byzantine tradition, the first iconographer of the Theotokos. Numbered among the Seventy and counted with the four Evangelists, Luke is the only Gentile writer of the New Testament and the historian of the infant Church, whose two-volume work spans from the angel’s annunciation in the Temple to Paul’s preaching in Rome. Organized from his own writings (the Gospel and Acts, including the first-person “we” passages), the Pauline notices that name him (Colossians 4:14; 2 Timothy 4:11; Philemon 24), the earliest external testimonies (the Muratorian Canon, the Anti-Marcionite Prologue, Irenaeus, Eusebius), and the critical scholarship on the synoptic problem, the dating of Luke–Acts, and the iconographic tradition, the collection is built for both systematic study and machine-loadable reference.

Purpose

This collection serves as both:

  1. A human-readable study guide — organized by topic for systematic engagement with the life, writings, theology, iconographic tradition, repose, and veneration of St. Luke the Evangelist.
  2. A machine-loadable knowledge base — each file is self-contained enough to be loaded independently for context on a specific topic.

It is also a study in source-criticism applied to a figure who wrote a quarter of the New Testament yet whose biography is almost entirely inference: an author who never names himself, whose identity as “Luke the beloved physician” rests on the combination of his self-effacing prefaces with three brief Pauline greetings, whose Gospel sits at the center of the most argued literary puzzle in the New Testament (the synoptic problem), whose two-volume work is dated by serious scholars anywhere from the early 60s to the second century, and whose most famous attribute — that he painted the Mother of God from life — is a pious tradition that does not surface until the sixth century and was pressed into service in the iconoclast controversy. The careful handling of attestation, authorship, dating, and the iconographic legend is therefore not a footnote to this guide but part of its substance.

How to Use This Guide

  • For study: Start with Section 01 for Luke the physician and companion of Paul — the man behind the books — then Sections 02–03 for his two-volume work, the Gospel and the Acts, which together form a single literary and theological project. Sections 04–05 treat what Orthodox piety most loves in Luke: his portrait of the Theotokos in word (the infancy narrative, the Magnificat) and, by later tradition, in image (the first icons). Section 06 draws out his theological signature; Section 07 is the source-critical centerpiece, where the synoptic problem and the dating of Luke–Acts are handled with the most care; Sections 08 and 09 treat his repose, relics, veneration, and the honest state of the historical questions.

Primary Sources

The principal sources drawn upon in this guide:

  • The Gospel according to Luke — Luke’s first volume, cited by chapter and verse; its literary preface (Luke 1:1–4), the infancy narrative (Luke 1–2), the Magnificat (Luke 1:46–55), and the parables unique to Luke (the Good Samaritan, Luke 10:25–37; the Prodigal Son, Luke 15:11–32).
  • The Acts of the Apostles — Luke’s second volume, cited by chapter and verse, including the first-person “we” passages (Acts 16:10–17; 20:5–15; 21:1–18; 27:1–28:16) on which the case for Luke’s companionship with Paul largely rests.
  • The Pauline notices — Colossians 4:14 (“Luke the beloved physician”), 2 Timothy 4:11 (“Only Luke is with me”), and Philemon 24 — the three New Testament texts that name Luke and tie him to Paul.
  • The Muratorian Canon (c. late 2nd century, on the traditional dating) and the Anti-Marcionite Prologue to Luke — the earliest external witnesses naming Luke as author of the third Gospel and as a physician of Antioch.
  • Irenaeus of Lyons, Against Heresies 3.1.1 and 3.14.1, in the translation of Ante-Nicene Fathers Vol. 1 — the fullest second-century testimony to Luke as the inseparable follower of Paul who set down the gospel Paul preached.
  • Eusebius of Caesarea, Ecclesiastical History 3.4, in the translation of Nicene and Post-Nicene Fathers, Series II, Vol. 1 — the gathering of the early tradition that Luke was an Antiochene by birth, a physician, and the author of the Gospel and Acts.
  • The iconographic tradition — the attribution of the first icons of the Theotokos to Luke, attested no earlier than the sixth century (Theodore the Lector) and marshaled in the iconodule dossier of the Seventh Ecumenical Council (Nicaea II, 787).

Sourcing & Methodology

This collection is governed by the repository METHODOLOGY.md, and is shaped by three disciplines particular to its subject:

  1. Source-criticism of an anonymous author known by inference. Luke never names himself; his identity rests on the join between his prefaces, the “we” passages of Acts, the three Pauline greetings, and the second-century external witnesses. Per METHODOLOGY §2, Scripture is cited by chapter and verse, the patristic anchors (Muratorian Canon, Anti-Marcionite Prologue, Irenaeus AH 3.1.1, Eusebius HE 3.4) are named in work-and-division form, and the live disputes — authorship, the synoptic problem, the dating of Luke–Acts — are presented as structured [Disputed: ...] notes naming the positions and their proponents rather than resolved by assertion.

  2. The synoptic problem and the dating handled as open scholarship. Section 07 follows METHODOLOGY §3–4: the two-source theory (Markan priority plus Q; B. H. Streeter), the Farrer hypothesis (Mark without Q; Austin Farrer, Michael Goulder, Mark Goodacre), and the Griesbach/Two-Gospel hypothesis (Matthean priority; J. J. Griesbach, William Farmer) are named with their proponents and arguments; the dating range from c. AD 62 to the 90s and into the second century is given with the evidence on each side, none of it asserted as settled.

  3. The iconographer tradition pinned to attestation, not asserted as fact. Per METHODOLOGY §3.5, the tradition that Luke painted the Theotokos is reported as pious tradition with a late first attestation — it does not appear before the sixth century (Theodore the Lector) and was invoked in the iconodule cause at and around Nicaea II — and is never certified as historical fact. The relics tradition (Thebes in Boeotia → Constantinople in 357 → later Padua) is likewise pinned to its sources.

Important Caveats

  1. AI-generated content: This guide was generated by an AI assistant. While care has been taken to cite real sources and present the history and theology accurately, all content should be verified against primary sources before being relied upon for catechetical or academic purposes.
  2. Verification pass: Files in this collection are born compliant with METHODOLOGY.md §2–3: each date, quotation, and attribution was researched and given a disposition during composition; claims where the sources genuinely disagree carry structured [Disputed: ...] notes; and hagiographic and iconographic material is pinned to its earliest written attestation under §3.5 rather than asserted as fact. A residual bare [Verify] tag would indicate a file not yet processed; this collection contains none.
  3. An inferred biography: Almost nothing of Luke’s life is known with certainty apart from what his own writings imply, the three Pauline notices, and the second-century traditions gathered by Eusebius and the prologues. The honest state of the evidence is itself a topic of this guide (see Section 09).
  4. Contested authorship, sources, and date: The authorship of Luke–Acts (the traditional Luke-companion-of-Paul view vs. critical doubts), the synoptic problem, and the dating of Luke–Acts are all live scholarly disputes, treated explicitly in Sections 07 and 09.
  5. A late iconographic tradition: The attribution of the first Marian icons to Luke is a sixth-century-and-later tradition invoked in the iconodule cause; it is reported as such and not as the historical record of the apostolic age (Section 04).
  6. Not a substitute: This reference is not a substitute for reading the primary sources directly — above all the Gospel of Luke and the Acts of the Apostles themselves — nor for catechesis under a priest.

Tradition Labels

Each file is tagged with:

  • Pan-Orthodox (Apostle and Evangelist) — the default and only label for this collection: Luke is venerated across all the canonical Orthodox Churches as a holy apostle, one of the Seventy, and an evangelist, author of the third Gospel and the Acts, commemorated on October 18.

Cross-References to the Orthodoxy Guide and Sibling Collections

  • Orthodoxy: Holy Scripture — the canon and inspiration of the Gospels and Acts within which Luke’s two volumes stand.
  • Orthodoxy: The Theotokos — the Mariological doctrine for which Luke’s infancy narrative and Magnificat are foundational scriptural witnesses.
  • Orthodoxy: Icons and Iconoclasm — the theology of the holy images in whose defense the Luke-the-iconographer tradition was invoked.
  • St. Apostle Paul — the apostle whose missionary journeys, imprisonment, and voyage to Rome Luke shared and recorded, and who names him in his letters.
  • St. John of Damascus — the great defender of the holy icons whose theology of the image gives the dogmatic frame for the iconographer tradition.
  • St. Irenaeus of Lyons — the second-century witness whose Against Heresies gives the fullest early testimony to Luke as Paul’s follower and the four-Gospel canon.
