Introduction
AUTHORSHIP
The unanimous testimony of the manuscripts of this Gospel, early church tradition, and church history until the mid-nineteenth century is that the author was Luke, a traveling companion of Paulās. The fact that no other names were attached to this work is all the more remarkable since, as the author himself (the ptc. ĻαĻηκολοĻ
ĪøĪ·Īŗį½¹Ļι is masc., 1:3) states in his prologue, he was not an apostle or original eyewitness of Jesusā ministry (1:2ā3). The following is a brief summary of some of the evidence for Lukan authorship (more may be conveniently found in Bock, Theology, 32ā41; the introductions to the commentaries mentioned below; and in a comprehensive recent discussion of these introductory matters by C. Keener, Acts: An Exegetical Commentary vol. 1, Introduction and 1:1ā2:47 (Grand Rapids: Baker, 2012), 383ā434.
1.The earliest ms., a papyrus from c. AD 200 (×§75), states at the end of the Gospel that it is the āGospel according to Luke.ā This is the title that is consistently found either at the beginning or end of Luke in nearly all uncial mss. (even at the top of each codex page in abbreviated form in Vaticanus and Sinaiticus, Edwards 4). Thus, it is unlikely to have been an anonymous text (M. Hengel, The Four Gospels and the One Gospel of Jesus Christ and J. Bowden Harrisburg: [Trinity Press International, 2000], 37).
2.The widespread testimony of the early church is that the author was āLukeā and that this Luke was a traveling companion of Paulās. Some of this external evidence includes references to Luke as author and companion of Paul in the Muratorian Canon, Irenaeus (Against Heresies 3.1.1; 3.14.1ā4), the āantiāMarcionite prologueā to Lukeās Gospel, Clement of Alexandria (Stromata 5.12), Tertullian (Against Marcion 4.2.2), Origen (On First Principles 2.6.7), and Eusebius (Ecclesiastical History 3.4.6; 3.24.15). Justin Martyr (Dialogue 103; c. AD 160) cites the text of Luke 22:44 as written by one of those who followed the apostles.
3.This connection between the author as āLukeā and a companion of Paul finds confirmation (a) within Luke and Acts, and (b) in three allusions in Paulās letters. First, on the basis of the prologue to Acts (referring to his ĻĻįæ¶Ļον λόγον and repeating the addressee as āTheophilusā), it is likely that Acts is written by the same author as Lukeās Gospel (this is confirmed with a number of parallels and repeated patterns across Luke-Acts). Within Acts, the āweā passages (where the author uses the first person plural: 16:10ā17 [Troas to Philippi]; 20:5ā21:18 [PhilippiāTroasāMiletus to Jerusalem]; 27:1ā28:16 [Caesarea to Rome]) imply that the author of these two works joins the journeys of Paul at these points (noted by Irenaeus, Against Heresies 3.14.1). Second, an individual called Luke is also identified in the Pauline literature as a companion of Paulās (Col 4:14; Phlm 24; 2 Tim 4:11). When one considers all the companions of Paul mentioned in the letters, these few refs. to someone named Luke who is with Paul (in Rome) do not make Luke an obvious choice if late-second-century writers were looking for a name to attach to this Gospel and that would result in unanimity across the mss. and early church tradition (pace Bovon 1.10).
DATE
Estimating a precise date for Lukeās Gospel is more difficult given the fact that (unlike the name) a date is not given in the title. The previous discussion of authorship does, however, have a bearing on this. If the author is a companion of Paulās, as the internal and external evidence indicates, then the date cannot extend too much later than toward the end of the first century (the citation from Justin Martyr [above] means the latest possible date is c. AD 160). The prologue itself indicates that any date in the second half of the first century would be possible (i.e., based on the reports of original eyewitnesses). The decision about a more precise date, however, depends on how one evaluates the following:
1.Given the likelihood that Acts was written after Lukeās Gospel (Acts 1:1), the date of Lukeās Gospel depends in part on when one dates Acts. This in turn depends on whether the end of Acts indicates the time when Acts was written (i.e., soon after the ātwo whole yearsā of Paulās imprisonment [Acts 28:30; thus, soon after approx. AD 62]; internally, the narrative of Acts does not show an interest in later debates such as Gnosticism, etc.). Although Acts is not primarily about Paul so that Luke must tell of all the events that transpired in Paulās life (i.e., the outcome of his trial and his [later] execution), nevertheless, it is the arrival of Paul (and companions) in Rome that Luke describes rather than the arrival of the gospel in Rome (note Acts 28:14ā15).
2.Given the similarities among the Synoptic Gospels, the date of Lukeās Gospel also depends in part on whether one thinks there is literary dependence among these Gospels and, if so, whether that literary dependence requires Markan priority. Obviously if Luke used Mark, then the date of Luke depends on the date of Mark. Even so, 30ā40 years after the death and resurrection of Jesus is plenty of time for Gospels to be written and circulated. There does not appear to be a consensus on the answer to this complex question, and it seems unwise to base too much on proposed reconstructions of literary dependence. The prologue does not require Lukeās Gospel to depend on late written Gospels (see the comments on 1:1ā2).
3.The date of Lukeās Gospel may also depend on whether one requires Jesusā descriptions of the destruction of Jerusalem to have been written after that destruction (i.e., after AD 70). This may relate to how one views Jesusā other predictions in Lukeās Gospel, but, as many have noted, the language is sim. to OT prophetic judgments (see comments on 19:43ā44; 21:20ā24) and need not require a postāAD 70 date. Other opportunities for pointing out the destruction of the temple do not seem to be taken up by Luke (e.g., 24:53; Acts 3ā7).
As indicated above, although not essential for the purposes of this guide, my own preference is for a date somewhere between the mid-50s and early-60s (in addition to the introductions to the commentaries and the sources cited there, see also the often overlooked discussion [for an early date] in J. Wenham, Redating Matthew, Mark and Luke [London: Hodder and Stoughton, 1991], 223ā38; Keener [392ā93] argues for a date soon after AD 70 for Lukeās Gospel).
AUDIENCE
The name of the addressee, Theophilus, mentioned in the prefaces of Luke and Acts, does not provide any decisive evidence for the audience of these books (the following brief discussion summarizes Thompson, 23ā25; see the exegetical comments on 1:1ā4 for more details). A common Greek name, it was used by both Jews and Greeks. Theophilus may well have been an official (ĪŗĻį½±ĻιĻĻε) and patron of Lukeās writing project. Even so, a wider audience is assumed even when a patron is named. Lukeās repeated use of the plural pronoun āusā in his preface to the Gospel indicates that he identifies with the readership of his work. As Marguerat notes, āThe narrative which follows (the Gospel and Acts) takes place within a readership composed of a common faith in the saving events (the āevents . . . fulfilled among usā) and a common adherence to a tradition (āhanded on to us by those who from the beginning were eyewitnessesā)ā (D. Marguerat, The First Christian Historian [Cambridge: Cambridge University Press, 2002], 23ā24). Thus, a Christian readership is most likely implied by the preface to Lukeās Gospel (see the exegetical comments on 1:1ā4...
