Titles in the 14-volume Early Christianity Collection -- Classic Studies and Documents are:

The Church in Rome in the First Century, by George Edmundson

Eight lectures (Bampton Lectures, 1913) on the subject, by an Anglican cleric/scholar who takes a more positive view of the tradition(s) regarding Peter and the founding of the Church in Rome than most critical scholars at the time (and since). [general academic, with fairly extensive footnotes], [c.1913]

History of Dogma, by Adolf von Harnack

Harnack's influential Dogmengeschichte (History of Dogma, 6 vol. English ed.), a landmark work that is still regularly consulted and cited by historians and theologians. Harnack was almost universally regarded as the leading expert on early Church History and Doctrine, especially for the ante-Nicene period. His ground-breaking work helped establish more serious critical study of the early Christianity and the Fathers. [Scholarly, with extensive documentation], [1894 Engl. Ed., transl. from the German]

Mission and Expansion of Christianity in the First Three Centuries, by Adolf von Harnack   

This work on early Christian history is somewhat more approachable and easier to follow than Harnack's great work on Dogma, though it still is quite scholarly, especially in the footnotes. It focuses on the social, intellectual and ethical contours of the early church, largely in regard to the Greco-Roman cultural environment [Scholarly, with extensive documentation], [c. 1902; 1908 Engl. Ed., transl. from the German]

What Is Christianity?, by Adolf von Harnack

A series of lectures given extempore at the University of Berlin, Winter 1899-1900, covering the history and development of doctrine, as well as the social and intellectual structure of Christianity. The bulk of the lectures focus on the Apostolic and Early Church period, but the last few extend in to the Medieval and Reformation periods. Before plunging into the author's History of Dogma. These lectures provide a good introduction to the framework and approach used in analyzing and organizing the material used in von Harnack's History of Dogma volumes. [General academic, minimal documentation], [1900; 1908 Engl. Ed., transl. from the German]

Two Lectures: On Monasticism and the Confessions of Augustine, by Adolf von Harnack

Two short works - lectures, or treatises, less academic in approach than many of Harnack's more famous works. His treatment of 'Monasticism: It's Ideals and History' provides a useful survey; of course, coming out of the rational Protestantanism of the 18th & 19th centuries, he has little sympathy for the ascetic ideals of monasticism, but his objective knowledge of the material is sound. The Augustine lecture, much shorter and is a helpful introduction or supplement to the reading of Augustine and his famous autobiography. [General academic, minimal documentation], [c. 1900; 1911 Engl. Ed., transl. from the German]

On the Apostles' Creed, by Adolf von Harnack

This is an article on the Apostles' Creed (from Herzog's Realencyclopädie), and is one of the bits of scholarly analysis for which Harnack is justly famous. It also provides a good example as to how critical analytic tools began to be applied in earnest to the field of Patristics and Early Church tradition. He provides a detailed examination: early references to the Creed, its original provenance, how it came to take the shape it now has, etc. Clearly, contrary to tradition, he maintains the famous Creed is not a product of the Apostles per se -- on this, virtually all modern scholars are agreed. However, it is also clear that such a rigorous application of critical analysis was highly controversial with traditionalists of the time. [Scholarly], [1890s; 1901 Engl. Ed., transl. from the German]

The Christian Ecclesia, by F. J. A. Hort

A series of lectures given at Cambridge in the autumn of 1888 and 1889. It is effectively a detailed word study on the term "Ecclesia" (Gk.  )Ekklhsi/a), along with how the term came to be understood conceptually in the Early Church. As such, the lectures touch on a variety of theological and ecclesiologial issues, and a number of key NT passages are examined closely. The work ends with a sermon (1890) on the occasion of the consecration of his colleague Bishop Westcott, key text Eph. 6:12-13. [Academic/scholarly, but with limited documentation and footnotes], [1897, published posthumously]

Church and the Ministry in the Early Centuries, by Thomas M. Lindsay

A series of in-depth lectures (Cunningham Lectures) on a difficult topic. The author, a scholar in the Free Church tradition in Scotland, juxtaposes two models of authority and government in the Church: (Spiritual) Gifts (esp. the prophetic) and fixed Church Offices, showing the interplay and dynamic of both throughout history. Overall a careful, thorough treatment, which modern-day Protestants should find interesting. [General academic, but with extensive documentation in the footnotes], [1903]

Christian Hymns of the First Three Centuries, by Ruth Ellis Messenger

A short tract from the series "Papers of the Hymn Society", written by a professor of hymnology/musicology. It provides a good introduction/overview of the subject with several dozen early hymns (or extracts) provided in translation. [1930-40]

Short Papers on Church History, by Andrew Miller

The author is a Baptist/Brethren pastor and revivalist preacher who is chiefly known today for his writings on Church History, of which these "Short Papers" are representative. Most notable is the historicist framework he uses, where each of the Seven Churches of Rev. 2-3 represents a period of church history. This sort of interpretive approach was once quite popular among earlier Protestants reaching back into the Reformation, though it is not much in favor today. The overall message is one of a steady decline from Apostolic times to the present, with a decided anti-Roman-Catholic polemic (though more nuanced than that of the typical firebrand preacher) [Traditional-conservative; General academic, pastoral. [1873]

Early Years of Christianity, by Edmund de Pressensé

An oft-cited History by the distinguished French Protestant preacher and statesman (and student of the great Church historian Neander), this volume covers the Apostolic Period, including a survey of some key NT critical issues [General academic, with fairly extensive footnotes], [1968, transl. from the French]

History of the Origins of Christianity, by Joseph Ernest Renan

Renan's famous 7-volume history, like his earlier "Life of Jesus" provides no shortage of controversial points, but is also a learned, eloquent work, altogether typical of the liberal-theological critical scholarship in Europe at the time. Renan was a gifted scholar (in the fields of theology, Semitics, and Biblical criticism), and a full-blooded critical skeptic. This shows most vividly in his view on miracles and the supernatural; note also the space he devotes to the learned pagan opponents of Christianity (Lucian, Celsus, M. Aurelius). These issues notwithstanding, there is much of interest to read along the way. [General academic with liberal-critical viewpoint, scholarly details, limited documentation], [1868-1881, transl. from the French]

Early Christian Fathers, by Cyril C. Richardson

This standard set of translations covers most of the so-called Apostolic Fathers (except for Hermas and the epistle of 'Barnabas'), works of two of the Apologists (Justin Martyr's 1st Apol. and Athenagoras' 'Plea'), and selections from Irenaeus' Against Heresies. As such the material parallels vol. 1 of the Ante-Nicene Fathers, but with more recent translations, and better, up-to-date introductions. There is also a useful introduction to the historical background of the writings. Any seminary/theology student will likely have owned, or at least used, a copy of this book. [General academic, with some scholarly detail], [1953]

Sketches of Church History, by James Craigie Robertson

A well-known work by the distinguished professor of Church History and canon of Canterbury. Part I covers the Early Church period (up to c. A.D. 600), and Part II up to the time of the Reformation. [General academic], [1878]

The Beginnings of Christianity, by Paul Wernle

A two volume work, based on lectures in NT Theology given in 1900, by the professor at the University of Basel. Overall, it is a vivid and engaging work. [General academic, minimal documentation], [1903-4, transl. from the German]

 Titles in the Classic New Testament Studies 31-volume Collection are:

 Introduction to the New Testament, by Louis Berkhof  —  An investigation of the history and purpose of the Gospels and Epistles in the New Testament. Berkhof's sections begin with a brief outline followed by a comprehensive look at the characteristics, authorship, composition, and canonical significance of each New Testament book. Introduction relies on the findings of a wide range of New Testament scholars including the early Church Fathers. Berkhof's references are easy to navigate making this a prime text for student study, which it was during Berkhof's tenure at Calvin Theological Seminary where he taught for nearly 30 years.

The Miracles of Jesus, by Karl Beth —  A historical-critical and history-of-religion analysis written in response the the more radical-skeptical 19th cent. treatments of the 'historical Jesus'. The author is firmly in the line of German scholarship stemming from Harnack's historical research and writings on the transmission of scripture through the early church fathers.

Causes of the Corruption of the Traditional Text of the Gospels, by John W. Burgon — A valuable treatment of New Testament textual criticism, especially the issue of textual 'corruption' resulting from the rise of variant readings from a late 19th cent. perspective. The chapters provide a still-useful overview of the types and causes of these variant readings, with many examples from the Gospels. The author is also a strong adherent of the 'Majority Text', and a pronounced opponent of the approach taken by Tischendorf, Westcott & Hort, etc., in their critical editions of the New Testament.

The Last Twelve Verses of the Gospel of Mark, by John W. Burgon — A vigorous and learned defense of the originality of the 'long ending' of Mark (16:9-20). In Burgon's day, following the discovery of Codex Sinaiticus [a] and Vaticanus [B], critical scholars were already doubting the originality of these verses; despite Burgon's work of reviewing and refuting all supposed evidence produced against these verses. He proves some false, misconstrued, and none of any force in proving the verses anything but genuine. No one has ever dared to answer Burgon point by point. Burgon poses stubborn fact to which critics offer subjective opinions, circular reasoning, but no facts. The tide of opinion today is even further against him; evangelical scholars are split on the question, tending toward the critical view.

The Gospel According to St. Mark, by J. A. Chadwick — A popular devotional/expository commentary (from The Expositor's Bible). 

Lectures on the Acts of the Apostles, by John Dick —  A Scottish preacher and professor of Theology, Dick's fame rests primarily on these Lectures on Acts, which were and still are popular in published form. Expository, with some historical background and detail provided.

The Origin of the New Testament, by Adolf von Harnack — Though titled "Origin of the New Testament", this is really a study on the use of the New Testament text in the Early Church, with the purpose of demonstrating that the New Testament writings were already known and in use in the 2nd century A.D. Harnack and Tischendorf perceived the need to refute the critical scholars of the 19th and early 20th century who claimed that many of the NT books weren't written until the 2nd century (or later). Harnack is foremost known as a Patristics scholar, with pioneering work in the critical study of Church History and the History of Dogma.

Commentary on Ephesians, by Charles Hodge — Best known for his Systematic Theology, Hodge's New Testament commentaries are still highly regarded in Reformed circles. This work on Ephesians is extremely thorough and deals extensively with the Greek text.

The Epistle of James, by F. J. A. Hort — A commentary based exclusively on the Greek text by one of the foremost NT textual scholars (half of the team that produced the famous 1881 critical edition). Very detailed, with a thorough introduction; but the commentary itself was unfinished due to the author's death.

Johnson, Barton Warren — Commentary on John Written by a distinguished American minister, probably best known for his People's New Testament, this Commentary on the gospel of John is quite a thorough work. It is subtitled Volume 3 apparently of a larger NT commentary ("A Commentary for the People").

Dissertations on Theological Subjects Connected with the Study of St. Paul's Epistles, by Benjamin Jowett — A collection of interesting essays touching on key theological points from Paul's epistles and theology. Written largely from the standpoint of the History of Religions and Philosophy, his scriptural interpretations were rather controversial at the time from his perspective as a (somewhat unorthodox) Greek scholar who specialized in the works of Plato.

The Epistles of Peter An Expository Commentary on Both Epistles, by J. H. Jowett — In this classic study, distinguished British/American pastor J.H. Jowett deals with passages which are at the same time full of meaning and difficult in terms of interpretation. Jowett's skills of interpretation are blended and expressed through the vehicle of a unique literary style in a commentary that is both scholarly and devotional.  

The Friend on the Road and Other Studies in the Gospels, by J. H. Jowett — A series of approx. 60 short homilies or sermon illustrations, very much in the simple devotional style.

From the Talmud and Hebraica, by John Lightfoot — From a landmark 6-vol. work, this is an exegetical commentary on Gospel passages citing relevant background or supplementary information from the Talmud and other Rabbinic sources (as they were known and understood at the time). In addition to the verse-by-verse commentary, there are supplemental geographical and cultural notes. 

Commentary on the Acts of the Apostles, by J.W. McGarvey —  An expository commentary by the distinguished American pastor and scholar.

The Four-fold Gospel, by J. W. McGarvey and Philip Pendleton — A work chronicling the life of Christ, which was intended especially for use by Sunday School teachers. The detailed format is handled effectively, and each parallel section/event has a numerical index number (1-145). Theologically conservative, though not polemical, it has all of the expected harmonizing tendencies and explanations.

Moffat New Testament Commentary, by James Moffat — (General Epistles: James, Peter, Jude) A commentator and professor of church history, Moffat is no doubt best known for his popular (and occasionally controversial) Moffat Bible translation. The Moffat New Testament Commentary series was written 1928-49; this is the volume on the General Epistles. His commentaries are thorough and exegetical, but do tend to be theologically critical of the standard theories regarding biblical authorship.

Messages from the Epistle to the Hebrews, by H.C.G. Moule — Traditional and conservative, this is an exegetical and devotional commentary, from the Anglican bishop better known for his poems and hymns.

Expositions of the Epistles, by Augustus Neander — (Philippians, James, 1 John) From the famous Church historian, these expositions, intended to be part of a larger series of commentaries, cover three of the Epistles. They are generally exegetical, but the work on Philippians is presented more in summary fashion.

The Life of Christ, by Augustus Neander — Neander's famous Life of Christ, written as a direct response to D. F. Strauss' Life of Jesus. Like many critical German scholars of the time, he felt the need to answer the more radical critical theories of Strauss, F. C. Baur, et al. This work is important for its historical context of grappling with ideas and theories —  of German scholarship which modern American evangelicals tend to dismiss.

Romans Verse by Verse, by William R. Newell — An exegetical commentary on Romans, typical of Newell's work, which remains highly regarded in evangelical circles.

Pink, Arthur W. — Why Four Gospels? An introductory study of the Gospels, focusing on aspects and elements unique to each, with certain passages examined in more detail.

Was Christ Born in Bethlehem?, by W. M. Ramsay — A famous study on the Lukan birth narrative, especially with regard to the historical problem and the historicity of the Gospel in general. As such, it has proven quite popular over the years as an aid to New Testament apologetics.

St. Paul the Traveler and Roman Citizen, by W. M. Ramsay — Ramsay, a classics scholar and well-traveled geographer, made important contributions to the study of Early Christianity and the historical-cultural background of Christianity in relation to the Roman Empire. This life of Paul has been extremely popular for its detailed historical chronology which integrates information from the Epistles and Acts.

Letters to the Seven Churches of Asia, by W. M. Ramsay —  A thorough treatment of the historical background of Revelation 2-3.

The Johannine Writings, by Paul W. Schmiedel — An introduction and survey of the Johannine Writings (the Gospels, Epistles and Revelation), but the vast majority of the book is devoted to the Gospel, especially its historicity and relation to the Synoptics. Schmiedel, a professor of theology and NT exegesis typifies German critical scholarship (from an evangelical point of view) - penetrating analysis, with a more liberal-critical viewpoint.  

Origin of the Four Gospels by Constantine Tischendorf — One of the most famous and influential of all New Testament scholars, Tischendorf's discovery of the Codex Sinaiticus is legendary, and his numerous critical editions of the NT mark him as a pioneering text-critical scholar. This work demonstrates the historical witness of the four gospels in the early church; namely, that they were attested and in use, rather than being written by the second century A.D.

When Were Our Gospels Written?, by ConstantineTischendorf — A bit more detailed and organized work covering much of the same subject matter as above; it also includes a narrative of the discovery of Codex Sinaiticus.

Commentary on the Epistles to the Seven Churches, by R.C. Trench — (Rev. 2-3) A thorough exegetical treatment of Rev. 2-3, written by the distinguished NT scholar and Anglican archbishop.

The Sinlessness of Jesus, by Carl Ullmann — Written by a distinguished German professor of church history and dogmatics, this work (subtitled "An Evidence for Christianity"), is, like Neander's “Life of Christ”, an answer to D. F. Strauss' Life of Jesus, and the more radical-liberal historical criticism it represents.
