Divinations: Rereading Late Ancient Religion

Border Lines: The Partition of Judaeo-Christianity

Rate this book
The historical separation between Judaism and Christianity is often figured as a clearly defined break of a single entity into two separate religions. Following this model, there would have been one religion known as Judaism before the birth of Christ, which then took on a hybrid identity. Even before its subsequent division, certain beliefs and practices of this composite would have been identifiable as Christian or Jewish.In Border Lines , however, Daniel Boyarin makes a striking case for a very different way of thinking about the historical development that is the partition of Judaeo-Christianity. There were no characteristics or features that could be described as uniquely Jewish or Christian in late antiquity, Boyarin argues. Rather, Jesus-following Jews and Jews who did not follow Jesus lived on a cultural map in which beliefs, such as that in a second divine being, and practices, such as keeping kosher or maintaining the Sabbath, were widely and variably distributed. The ultimate distinctions between Judaism and Christianity were imposed from above by "border-makers," heresiologists anxious to construct a discrete identity for Christianity. By defining some beliefs and practices as Christian and others as Jewish or heretical, they moved ideas, behaviors, and people to one side or another of an artificial border—and, Boyarin significantly contends, invented the very notion of religion.

Don't read this review if your faith depends on believing your scriptures and related writings are historical documents.

Well, of course they are historical documents. What I mean is don't read this if you take them literally as history, meaning that for you their truth claims are established by their being the historical events and perspectives on which your faith is founded.


I used to have a dim view of Daniel Boyarin based on what I thought he was saying in some very short vignettes. Looking back at something I wrote nearly nine years ago, I wasn't impressed by him, based on some short vignettes. This book changed my mind, which I shouldn't have made up based on such limited information -- but that's what so often happens, doesn't it?

Thanks to my husband Dennis for bringing this book to my attention.

As to when Christianity and Judaism became separate, people think, if they bother to think of it at all, that some groups remained Jewish while others followed Jesus and became Christian. Meanwhile, or so they think, there were some Jewish Christian groups who were not looked on kindly by either Jews or Christians and ultimately were not allowed to exist. The "Ebionites," for example.

Boyarin argues that the changes and incursions that occurred were not geographical divisions among various groups of people, but were theological. The differentiation that occurred was theological.

Makes sense, since back then they didn't have the internet. They didn't have television. Or radio. Or telegrams. Or even the printing press. They could get letters, sometimes. Even though travel was arduous, they could receive visitors. The divisions of which we're speaking didn't occur in 34 or 70 CE, or when the Gospels were written down (at which time there was not yet an official Christian canon). How could the word have been gotten out to every hill and valley?

According to Boyarin, the theological distinctions we now accept did not exist. Instead beliefs were mixed and variously distributed. How did they settle out into theological claims that separated Christians and Jews?

He begins with the story of a metaphorical border line and a bicycle-mounted smuggler whom the border guards can't catch. They know he's a smuggler, but where is he hiding the contraband? Each time he crosses the border line, the guards search him for it, but they find nothing. What is he smuggling?

The answer: bicycles.

That is to say, the bicycles are the theological concepts being smuggled back and forth across that border line. And those inadvertent exchanges between groups led in time to the settling out of the theological particulate that came to define Rabbinic Judaism and Christianity.

Views we think originated with Christianity had long been prevalent in the landscape of Judaism. During the formation of Rabbinic Judaism and Christianity, views we now think of as "Christian" were "exported" from Judaism and "imported" into Christianity, and vice versa, via this "smuggling" process. Boyarin particularly focuses on Logos as a mediating figure between Heaven and earth -- God and humanity -- and how that concept became an earmark of Christianity while rejected by Jews as the "two powers in Heaven" view.

The way Boyarin shows this is by meticulous focus on scripture and other ancient writings in the context of reference to the ideas of other scholars in the field. He progresses little by little to make his various cases, with much citing of prior theories and books. And with many footnotes.

I find this exciting.

The settling out did not occur in short order as we tend to think, but over centuries, fourth for Christianity and late fifth/sixth for Judaism. This is because the powers-that-be weren't so in the beginning, but had to establish their respective hegemonies. That took time.

The way things would be seen needed to be nailed down, and the chain of tradition/apostolic succession established -- not from the beginning, as we like to think, but working backward, to create the edifice to support the approved conclusions.

Until this enterprise began, there was no "heresy" in our sense. There was the Greek word "hairesis," referring to a school of thought. Only after Christianity -- and, for a few centuries, Judaism as well -- established an orthodoxy, a right way of understanding, did heresy in our sense make its appearance. In a fascinating move, Boyarin refers to such an orthodoxy as a "church," whether Christian or Jewish: a right way of thinking and believing.

Boyarin asserts that Christians invented the concept of religion as we know it.

You'll probably find that odd, for surely the Romans and others, and beyond the known world, Asians (Hindus, Buddhists and the like) had religion. Well, we think they did because we're reading our current understanding of the concept back into their times. They did have practices and a way of life, but what they did not have was a free-standing attribute of a person that could be accepted, rejected or replaced. That's what was new. What other groups had were undistinguishable from their ways of life, that is, from their ways.

It's sometimes said that during the several generation-long Exile in Babylonia, after the destruction of the first Temple, that God became "portable," i.e., no longer tied to the land. Well, yes, but Jews/Judeans were still Jews/Judeans. Their Hebrew way went right long with them. In those years of the sixth century BCE, it remained their way of life, not an attribute or "faith" in the modern sense.

Why did the new concept, religion, emerge?

It was needed because Christianity had an identity crisis. They were not a historical people with a traditional way of life -- or, rather, they began as Jews but had moved toward absorbing others from beyond the group traditionally viewed as Jews -- and were now possessed of a new faith they wanted to spread to all and sundry.

Perhaps our present tendency to retroject our current understanding of religion back into the past is causing a confusion some find useful. The Establishment Clause of the First Amendment does not permit the insertion of the dominant faith into the public sphere. But the Free Exercise Clause, by broadening religion from the tenets of the dominant faith to ways or practices that cannot be suppressed, leads to the insertion of those ways and possibly to the dismantling of the Establishment Clause by those so inclined.

At any rate: new stuff, convincingly presented.

I did think his support for the assertion that Judaism quit being a religion (in his sense) and reverted to being a way was more limited than I expected and was anticlimactic. But this book was published in 2004. Maybe he's since had more to say.

Recommended for those with curiosity about these things. And fortitude: it's not that long -- 228 pages -- but then there are those end notes, amounting to another 146 pages.

I personally don't think learning about these things undermines religion. I think I'm inclined toward the Spinozan variety, though. (I say that humbly, considering my limited understanding of Spinoza and my variations on the theme.)

Anyone interested in the origins of Christianity and its development into the Patristic era will, at some point, have to account for the parting of ways between Christianity and Judaism. It is this popular notion of "parting ways" that Daniel Boyarin contests in his book, Border Lines: The Partition of Judaeo-Christianity. As the subtitle makes clear enough, Boyarin detects, not a peaceful, inevitable split between these two "religions", but a partition - an enforced dissolution.

Readers be warned, this is a rather complex work. Boyarin approaches the phenomena as a post-colonial historian. Which, if I were to summarize, means that he walks into the past holding everyone suspect. Any historical event is an opportunity to dig up an underlying conspiracy. And not the kind of conspiracy that consists of bizarre, extraordinary events. But the kind that lurks within seemingly mundane actions. No one is innocent - all are participating within the power structures of the day and often unknowingly marginalizing the weak and uneducated. The sociological theories that contribute to the post-colonial project are quite sophisticated. The terminology will likely be new for those who are unfamiliar with PC thought; it certainly was for me.

In an attempt to present clearly and briefly Boyarin's central thesis, I will have to limit the comprehensiveness of this review. Many of the smaller arguments and sub-points will regretfully be unstated.

Boyarin's reconstruction of the interaction between Christianity and Judaism is as follows. Christianity began as a sect within Judaism - and continued so throughout the New Testament period. It was not until the time of Justin Martyr, the mid 2nd century, that Christianity began to truly become "other" than Judaism. This "parting of ways" was not a natural process determined by the difference of theology between the two entities. Rather, it was an imposed partition rendered by the heresiologists (i.e., Justin Martyr). On Boyarin's account, the heresiologists were not only defending orthodoxy, they were constructing it. They were not simply identifying heresies and heretics, they were producing them.

In doing so, they were constructing their own identity. Because Christianity had no specific geographic or ethnic qualities, she had to find here identity within beliefs. It was theology which unified, not common ancestry. This detachment of religion from ethnic and cultural ties is what Boyarin terms the "disembedding" of religion. Essential to Boyarin's account of Christianity's identity-formation-through-orthodoxy, is the role it plays for Judaism of the late antiquity. Prior to the ante-Nicene heresiologists, Judaism was a conglomerate of Judaisms - a coalition of sects, all under the umbrella of Judaism. However, upon the (dubious?) work of Justin Martyr, Judaism was rendered a "religion" like Christianity. It became an orthodoxy to which one must subscribe if he wishes to maintain his Jewish identity. According to Boyarin, this construction of Jewish orthodoxy was in large part due to Justin's production of Christian orthodoxy. Christianity set itself over against Judaism. To be a Christian was to be a not-Jew. Thus, Justin needed to determine what it was to be a Jew - strictly so a Christian could not be that.

Thus, the pluralism that was allegedly present prior to Justin, was dissolved under his labor. The border lines were drawn and their was now Christianity, and there was Judaism. Hybrids were deemed heretics.

Boyarin demonstrates his scheme through charting out the history of Logos theology. Logos theology being the belief in "two powers in heaven"; God Himself, and a second power, variously known as Wisdom, Memra, Sophia, etc. This was the portion I was especially looking forward to. According to Boyaring, this Logos theology, which has often been considered the doctrine which demanded Christianity's split away from Judaism, was not actually a Christian innovation. Rather, it was a notion deeply embedded within the Judaism of the 2nd Temple period. Complexity within the Godhead was not a novelty within the New Testament. On the contrary, Boyarin thinks it was likely predominant. Thus, the accounts which implement Logos theology as the key to the "parting of ways" are mistaken. However, it is clear within the 2nd century that this became a major contention between Jews and Christians. For Justin, a Christian was one who held to Logos theology and a Jew was one who rejected it. So how did this come to be?

Boyarin argues that Justin is not portraying Jewish orthodoxy when he records their rejection of Logos, rather, he is constructing it. Justin, or at least those like him, is responsible for the removal of Logos theology from Judaism. What once had a lasting heritage in Judaism became a strictly Christian doctrine.

Yet the story does not end there. Boyarin goes on to draw up the story of Judaism in the 6th century. Namely, the point in which it rejects the Christian innovation of orthodoxy. The game that the Christians had lured the Jews into playing, the game of "religion", would ultimately be rejected by the Jewish community. In his reading of the Babylonian Talmud, the pluralism recorded is not historical to the Talmud's references, but rather to the Talmud's redactors. The pluralism of late Judaism has been "remembered into" the history of the Rabbis. Judaism rejected its status as an orthodoxy, and became a reembedded religion. To be a Jew was no longer to hold to certain doctrine, rather it was to be a certain ethnicity. In the end, Judaism became something wholly other than Christianity, not simply in content, but in category. Judaism ceased to be a "religion" like Christianity. Thus, as it was in the days of the Apostles, one could again be a Jew and a Christian, or a Christian and a Jew.

I close with a few thoughts of my own. I think Boyarin has published an incredibly erudite and creative work. His reading of the Talmud was impressive and rather persuasive, and he certainly made imaginative connections while maintaing credibility. However, I am surprised he did not give any time to drawing up a history of the 1st century interaction between Judaism and Christianity. That lack seemed to be a major lacuna in this volume. Likewise, his suspicion toward all the actors of antiquity is a bit exhausting. But that goes more at his ideology than his history (Ah, I'm a fool - as if they can be separated). I also think that he has overplayed the presence of Logos theology. I don't doubt its presence within the 1st century theological milieu, however, I do doubt its dominance.

In truth, it was quite a bit of work to get through this one. I can't say I particularly enjoyed it, however, it was definitely provocative and served as a good wake up to the importance of the 2nd century for Christian theological development. Proper motivation to once more take a long look at the Church Fathers' role in the theological process. A decent book, no doubt, yet not likely one to which I will return often.

Note: This book was received free of charge in exchange for an honest review.

This book has excellent analytical methods and close readings of texts showing the mutual emergence of categories of Judaism and Christianity within the context of the Roman and Middle Eastern / Babylonian worlds. It is lucidly argued and densely supported.

"Earlier Christian groups (including, or even especially, the Johannine one) distinguished themselves from non-Christian Jews not theologically, but only in their association of various Jewish theologoumena and mythologoumena with this particular Jew, Jesus of Nazarth. The characteristic move that constructs what will become orthodox Christianity is, I think, the combination of Jewish messianic soteriology with equally Jewish Logos theology in the figure of Jesus."

"The vanquishing of real religious dissent in Israel and the safe haven of power and privilege which the Rabbis had achieved by the fifth century enabled a portrayal of themselves as the ultimate democrats and meritocrats. All who would once have produced real dissension were now firmly out of the community, so within: Let pluralism ring!"

Boyarin locates two key moments in the development of what we now call Christianity and Judaism: the second century, when thinkers in both camps developed the notion of heresy, and the late antique development of the Babylonian Talmud, which cemented the Rabbinical character of "Judaism," which, in contradistinction to Christianity, cherished endless disputation and dissensus, and disdained miracles and revelation; at the same time, Christians developed the notion of religion, a belief system disembedded from cultural practice (and, on this point, his diachronic philological analysis of "superstitio" vs. "religio" in the antique world works perfectly) and founded on revelation and miracles and on the unity of the "Fathers" (invented in the fifth century). Notably, there is no record of the disputations of Nicea.

The worst heretics for each camp were those who occupied the middle; each camp created itself as such, in fact, by defining itself against a pure conception of the other. This process of self-definition through othering is of course very familiar to anyone cognizant with postmodern philosophy; so too are the continual exclusions through which identity establishes itself. This is as true for the newly born Christians as Nicea as it is for the newly born Jews in the Babylonian Talmud: neither side is innocent, neither side is pure.

Along the way, Boyarin demonstrates the first- and second-century muddling of "Jew" and "Christian" through analysis of Logos theology, the notion of a second, distinct hypostasis of God (ditheism, more or less). This was a belief many "Jews" and "Christians" shared; and, as well, one that many did NOT share. The lines can be drawn, then, between those who believed in some form of the Logos (some of whom believed in the particular form of the Logos known as Jesus) and those that did not. Boyarin thus manages to save Logos Jews from accusations of being Hellenized: there is a non-Hellenic tradition of the incarnate Logos (Memra, Sophia, Metatron, Yahoel) that's picked up by Philo and as well by the opening to the Gospel of John, which Boyarin reads as a Midrash on the opening of Genesis. He also demonstrates that "both" "sides" ultimately do away with the Logos, the Rabbis by dissolving revelation in favor of disputation, and the Bishops by firming up the mysterious singularity of the Trinity, swallowing up the distinct Logos within a triune but still fundamentally singular God.

I'd give this 5 stars if it were more efficiently written. Boyarin repeats himself frequently; his paragraphs tend to be muddled, with key points buried in the middle and then raised again several pages later; he often engages with secondary sources in the body text rather than in the footnotes, where such disputes rightly belong. My dream version of this book would be about 50 pages shorter, with footnotes (not endnotes) about 50 percent longer. This would reduce the body text to about 100 pages, which would save the book from reading like a crazy quilt looks.

Although it has serious problems of readability if you do not know enough about the period, Boyarin's work is easily the most revolutionary thesis about the 'parting of the ways'--between Judaism and Christianity--to come out in recent memory. He argues that, in fact, neither Judaism nor Christianity existed before they constructed each other. See also Judith Lieu's Neither Jew Nor Greek?: Constructing Early Christianity (2004).

Boyarin is always an interesting read, but having read through Le Boulluec's treatment of Heresiology, it became clear that Boyarin is really just riffin/ripping off of Le Boulluec's Foucauldian treatment of heresiology. The innovation is in the denial of a "parting of the ways" beforehand, but this too is not tied to Boyarin's analysis.

On a personal note, I think the notion of Logos Theology as present in earlier writings (and certainly in Philo) is incorrect.

Deeply theoretical exploration of how “Judaism” and “Christianity” became distinct religions—after centuries of overlap. But fair warning: this is not a casual read. Boyarin writes like the Talmudic scholar and cultural theorist he is, engaging heavily with late antique texts, postcolonial theory, and religious taxonomy. The result is a work that is dense, academic, and at times punishingly intricate—but also illuminating.

The broad outline of the argument of this book is convincing. Early Jews having a Logos/divine mediator theology: less so.

This book should be required reading to any historian of religions and to anyone interested in Judaism and Christianity. Boyarin, in this book, shows how the Judaism (or better, Judaisms) of the Second Temple period are different from rabbinic judaism and with many variations and sects. Some of the judaisms in the period were binitarian. They believed that Logos/Sophia were a second entity, a "second God". This was later known by the rabbis as "Two Powers in Heaven". Boyarin shows that "Christianity" was basically another judaism sect, one that believed that the Logos incarnated as man. So Christianity was not so radical or different in terms of concepts from other judaisms of the period.

Another important analysis in the book is about how christianity "orthodox" leaders and rabbinic judaism leaders beginning in the second century started to develop a discourse on heresies/minim to create borders and boundaries between their own views versus others. Really an amazing book that explains the fantastic and variated world os Second Temple Judaism.

This was academic and thus a slow read, but I can see why it is highly recommended. Boyarin is a top scholar in Judeo-Christian studies, and his insights into the ancient vs. modern worldivew a incredibly helpful, specifically as related to the creation of the religious systems of Christianity and Judaism in the 2nd - 5th centuries. Boyarin's obvious insinuation, although left out of this book, is that the 1st century functioned in the ancient worldview.
