No wonder that the third Gospel has been pronounced, from a purely literary and humanitarian standpoint, to be the most beautiful book ever written. [1009]
The Style.
Luke is the best Greek writer among the Evangelists. [1010] His style shows his general culture. It is free from solecisms, rich in vocabulary, rhythmical in construction. But as a careful and conscientious historian he varies considerably with the subject and according to the nature of his documents.
Matthew begins characteristically with "Book of generation" or "Genealogy" (biblos geneseos), which looks back to the Hebrew Sepher toledoth (comp. Gen. 5:1; 2:4); Mark with "Beginning of the gospel" (arche tou euangeliou), which introduces the reader at once to the scene of present action; Luke with a historiographic prologue of classical ring, and unsurpassed for brevity, modesty, and dignity. But when he enters upon the history of the infancy, which he derived no doubt from Aramaic traditions or documents, his language has a stronger Hebrew coloring than any other portion of the New Testament. The songs of Zacharias, Elizabeth, Mary, and Simeon, and the anthem of the angelic host, are the last of Hebrew psalms as well as the first of Christian hymns. They can be literally translated back into the Hebrew, without losing their beauty. [1011] The same variation in style characterizes the Acts; the first part is Hebrew Greek, the second genuine Greek.
His vocabulary considerably exceeds that of the other Evangelists: he has about 180 terms which occur in his Gospel alone and nowhere else in the New Testament; while Matthew has only about 70, Mark 44, and John 50 peculiar words. Luke's Gospel has 55, the Acts 135 hapax legomena, and among them many verbal compounds and rare technical terms.
The medical training and practice of Luke, "the beloved physician," familiarized him with medical terms, which appear quite naturally, without any ostentation of professional knowledge, in his descriptions of diseases and miracles of healing, and they agree with the vocabulary of ancient medical writers. Thus he speaks of the "great fever" of Peter's mother-in-law, with reference to the distinction made between great and small fevers (according to Galen); [1012] and of "fevers and dysentery," of which the father of Publius at Melita was healed (as Hippocrates uses fever in the plural). [1013]
He was equally familiar with navigation, not indeed as a professional seaman, but as an experienced traveller and accurate observer. He uses no less than seventeen nautical terms with perfect accuracy. [1014] His description of the Voyage and Shipwreck of Paul in Acts 27-28, as explained and confirmed by a scholarly seaman, furnishes an irrefragable argument for the ability and credibility of the author of that book. [1015]
Luke is fond of words of joy and gladness. [1016] He often mentions the Holy Spirit, and he is the only writer who gives us an account of the pentecostal miracle. [1017] Minor peculiarities are the use of the more correct limneof the lake of Galilee for thalassa, nomikosand nomodidaskalosfor grammateus, to eiremenonin quotations for rethen, nun phor arti, hesperafor opsia, the frequency of attraction of the relative pronoun and participial construction.
There is a striking resemblance between the style of Luke and Paul, which corresponds to their spiritual sympathy and long intimacy. [1018] They agree in the report of the institution of the Lord's Supper, which is the oldest we have (from a.d. 57); both substitute: "This cup is the new covenant in My blood," for "This is My blood of the (new) covenant," and add: "This do in remembrance of Me" (Luke 22:19, 20; 1 Cor. 11:24, 25). They are equally fond of words which characterize the freedom and universal destination of the gospel salvation. [1019] They have many terms in common which occur nowhere else in the New Testament. [1020] And they often meet in thought and expression in a way that shows both the close intimacy and the mutual independence of the two writers. [1021]
Genuineness [1022]
The genuineness of Luke is above reasonable doubt. The character of the Gospel agrees perfectly with what we might expect from the author as far as we know him from the Acts and the Epistles. No other writer answers the description.
The external evidence is not so old and clear as that in favor of Matthew and Mark. Papias makes no mention of Luke. Perhaps he thought it unnecessary, because Luke himself in the preface gives an account of the origin and aim of his book. The allusions in Barnabas, Clement of Rome, and Hermas are vague and uncertain. But other testimonies are sufficient for the purpose. Irenaeus in Gaul says: "Luke, the companion of Paul, committed to writing the gospel preached by the latter." The Muratori fragment which contains the Italian traditions of the canon, mentions the Gospel of "Luke, the physician, whom Paul had associated with himself as one zealous for righteousness, to be his companion, who had not seen the Lord in the flesh, but having carried his inquiries as far back as possible, began his history with the birth of John." Justin Martyr makes several quotations from Luke, though he does not name him. [1023] This brings us up to the year 140 or 130. The Gospel is found in all ancient manuscripts and translations.
The heretical testimony of Marcion from the year 140 is likewise conclusive. It was always supposed that his Gospel, the only one he recognized, was a mutilation of Luke, and this view is now confirmed and finally established by the investigations and concessions of the very school which for a short time had endeavored to reverse the order by making Marcion's caricature the original of Luke. [1024] The pseudo-Clementine Homilies and Recognitions quote from Luke. Basilides and Valentinus and their followers used all the four Gospels, and are reported to have quoted Luke 1:35 for their purpose.
Celsus must have had Luke in view when he referred to the genealogy of Christ as being traced to Adam.
Credibility.
The credibility of Luke has been assailed on the ground that he shaped the history by his motive and aim to harmonize the Petrine and Pauline, or the Jewish-Christian and the Gentile-Christian parties of the church. But the same critics contradict themselves by discovering, on the other hand, strongly Judaizing and even Ebionitic elements in Luke, and thus make it an incoherent mosaic or clumsy patchwork of moderate Paulinism and Ebionism, or they arbitrarily assume different revisions through which it passed without being unified in plan.
Against this misrepresentation we have to say: (1) An irenic spirit, such as we may freely admit in the writings of Luke, does not imply an alteration or invention of facts. On the contrary, it is simply an unsectarian, catholic spirit which aims at the truth and nothing but the truth, and which is the first duty and virtue of an historian. (2) Luke certainly did not invent those marvellous parables and discourses which have been twisted into subserviency to the tendency hypothesis; else Luke would have had a creative genius of the highest order, equal to that of Jesus himself, while he modestly professes to be simply a faithful collector of actual facts. (3) Paul himself did not invent his type of doctrine, but received it, according to his own solemn asseveration, by revelation from Jesus Christ, who called him to the apostleship of the Gentiles. (4) It is now generally admitted that the Tübingen hypothesis of the difference between the two types and parties in the apostolic church is greatly overstrained and set aside by Paul's own testimony in the Galatians, which is as irenic and conciliatory to the pillar-apostles as it is uncompromisingly polemic against the "false" brethren or the heretical Judaizers. (5) Some of the strongest anti-Jewish and pro-Gentile testimonies of Christ are found in Matthew and omitted by Luke. [1025]
The accuracy of Luke has already been spoken of, and has been well vindicated by Godet against Renan in several minor details. "While remaining quite independent of the other three, the Gospel of Luke is confirmed and supported by them all."
Time of Composition.
There are strong indications that the third Gospel was composed (not published) between 58 and 63, before the close of Paul's Roman captivity. No doubt it took several years to collect and digest the material; and the book was probably not published, i.e., copied and distributed, till after the death of Paul, at the same time with the Acts, which forms the second part and is dedicated to the same patron. In this way the conflicting accounts of Clement of Alexandria and Irenaeus may be harmonized. [1026]
1. Luke had the best leisure for literary composition during the four years of Paul's imprisonment at Caesarea and Rome. In Caesarea he was within easy reach of the surviving eyewitnesses and classical spots of the gospel history, and we cannot suppose that he neglected the opportunity.
2. The Gospel was written before the book of Acts, which expressly refers to it as the first treatise inscribed to the same Theophilus (Acts 1:1). As the Acts come down to the second year of Paul's captivity in Rome, they cannot have been finished before a.d. 63; but as they abruptly break off without any mention of Paul's release or martyrdom, it seems quite probable that they were concluded before the fate of the apostle was decided one way or the other, unless the writer was, like Mark, prevented by some event, perhaps the Neronian persecution, from giving his book the natural conclusion. In its present shape it excites in the reader the greatest curiosity which could have been gratified with a few words, either that the apostle sealed his testimony with his blood, or that he entered upon new missionary tours East and West until at last he finished his course after a second captivity in Rome. I may add that the entire absence of any allusion in the Acts to any of Paul's Epistles can be easily explained by the assumption of a nearly contemporaneous composition, while it seems almost unaccountable if we assume an interval of ten or twenty years.
3. Luke's ignorance of Matthew and probably also of Mark points likewise to an early date of composition. A careful investigator, like Luke, writing after the year 70, could hardly have overlooked, among his many written sources, such an important document as Matthew which the best critics put before a.d. 70.
4. Clement of Alexandria has preserved a tradition that the Gospels containing the genealogies, i.e., Matthew and Luke, were written first. Irenaeus, it is true, puts the third Gospel after. Matthew and Mark and after the death of Peter and Paul, that is, after 64 (though certainly not after 70). If the Synoptic Gospels were written nearly simultaneously, we can easily account for these differences in the tradition. Irenaeus was no better informed on dates than Clement, and was evidently mistaken about the age of Christ and the date of the Apocalypse. But he may have had in view the time of publication, which must not be confounded with the date of composition. Many books nowadays are withheld from the market for some reason months or years after they have passed through the hands of the printer.
The objections raised against such an early date are not well founded. [1027]
The prior existence of a number of fragmentary Gospels implied in Luke 1:1 need not surprise us; for such a story as that of Jesus of Nazareth must have set many pens in motion at a very early time. "Though the art of writing had not existed," says Lange, "it would have been invented for such a theme."
Of more weight is the objection that Luke seems to have shaped the eschatological prophecies of Christ so as to suit the fulfilment by bringing in the besieging (Roman) army, and by interposing "the times of the Gentiles" between the destruction of Jerusalem and the end of the world (Luke 19:43, 44; 21:20-24). This would put the composition after the destruction of Jerusalem, say between 70 and 80, if not later. [1028] But such an intentional change of the words of our Lord is inconsistent with the unquestionable honesty of the historian and his reverence for the words of the Divine teacher. [1029] Moreover, it is not borne out by the facts. For the other Synoptists likewise speak of wars and the abomination of desolation in the holy place, which refers to the Jewish wars and the Roman eagles (Matt. 24:15; Mark 13:14). Luke makes the Lord say:, Jerusalem shall be trodden down by the Gentiles till the times of the Gentiles be fulfilled" (Luke 21:24). But Matthew does the same when he reports that Christ predicted and commanded the preaching of the gospel of the kingdom in all parts of the world before the end can come (Matt. 24:14; 28:19; comp. Mark 16:15). And even Paul said, almost in the same words as Luke, twelve years before the destruction of Jerusalem: "Blindness is happened to Israel until the fulness of the Gentiles be come in" (Rom. 11:25). Must we therefore put the composition of Romans after a.d. 70? On the other hand, Luke reports as clearly as Matthew and Mark the words of Christ, that "this generation shall not pass away till all things" (the preceding prophecies) "shall be fulfilled" (Luke 21:32). Why did he not omit this passage if he intended to interpose a larger space of time between the destruction of Jerusalem and the end of the world?
