The Center for Jewish Christian Understanding

“People in the West, even those who may imagine that they have emancipated themselves from Christian belief, in fact, are shot through with Christian assumptions about almost everything. . . All of us in the West are a goldfish, and the water that we swim in is Christianity, by which I don’t necessarily mean the confessional form of the faith, but, rather, considered as an entire civilization.”

-Tom Holland, award-winning historian and broadcaster,
author of 
Dominion: How the Christian Revolution Changed the World 

The Center for Jewish Christian Understanding is a think tank and research project grounded in original research on the theological roots of modern antisemitism. Its vision is a world in which antisemitism is impossible, because its causes have been understood and acknowledged, and are widely known, informing academics, journalists, and the public.

Vision

 

Our vision is to bring about a radically new understanding of the Jewish Christian relationship which creates the foundations of a world where antisemitism is impossible, because it is understood.

 

Mission  

 

Our mission is to act as an educational hub between a variety of organizations and scholars studying the profound and complex history of Jewish Christian relations.

 

Through education, scholarship, and dialogue, we are bringing to light the historical complexities of the Jewish Christian relationship and aim to expose the root cause of modern antisemitism—a strain of Christian theology that has distorted its own history and created a cultural theology of violence and hatred, and is rising again.

 

Why Us

Marginalia has over 100,000 readers and our publications are assigned in universities and classrooms around the world, have been read at Google, assigned to White House Staffers and members of European Parliament, and have been featured in The Browser, Arts & Letters, and the Max Planck Institute for the History of Science.

 

The Center for Jewish Christian Understanding will bring over 8 years of publications and new material to a wide audience seeking the intellectual, religious, and ethical resources they need to facilitate Jewish-Christian understanding. We’ve published the leading scholars in this area, including Daniel Boyarin, Paula Fredriksen, Rowan Williams, Susannah Heschel, Paul Franks, and others. 

 

In this season of liberation where Jews around the world will celebrate the exodus from Egypt
during Pesach, we are raising $50,000 to launch the Center and make it operational,
and thus begin to liberate the world from the shackles of antisemitism.

“Imagine a Christianity without Judaism: A bible with no Israel, no Torah, no law and prophets, and finally a Jesus without a history, revealing a god separate from and unknown to the world prior to Jesus’ appearance in history. In such an imagined act, one comes close to imagining the under-studied truth of modern Christian theology: that such a form of Christianity, a Christianity without Judaism, lies at the foundation of Protestant liberalism.”
