Monthly Programs

Most months a member will give a presentation, discussing a current work in progress, the research and writing process, or an area of personal interest and expertise. A collegial Q&A ensues, and the speaker can, if they wish, ask for suggestions for improvement in case they will be giving the talk at other venues. These programs are usually held at 2:00 PM on the third Sunday of the month, except for December; exceptions can be made as necessary. A digital projector and screen are available. Another member volunteers to take notes and write a report for the newsletter, or the speaker may provide a synopsis instead.

We try to have a speaker each month, though this is not always possible. Ideally, we schedule the programs as far in advance as possible. Members who are interested in giving a talk or other program (such as a film or exhibit tour) should email

Videos of some presentations can be viewed on our YouTube Channel.

Judaism, Christianity, and War
A presentation by Dan Kohanski
At almost any moment in recorded history, someone, somewhere, is at war. While wars are fought for many different reasons, when religion gets involved, it can change everything. In this presentation, Dan Kohanski explores how Judaism developed its theology of war from the experiences of the early Israelites and their descendants down to Roman times. Then he shows how Christians built on that history, and added their own experiences and beliefs, to fashion an approach to war that continues to impact the world today. Dan Kohanski has spent a lifetime studying the history and development of Judaism and Christianity. His current book, A God of Our Invention: How Religion Shaped the Western World, was published in 2023 by Apocryphile Press. This presentation is based in large part on chapter 6 in that book: "When God Goes Off to War." You are welcome to invite friends and colleagues to attend.
The presentation will be recorded, and the question-and-answer part will be posted on YouTube for IHS members only. If you don’t want to be on the recording, just make sure your video is off. And please remember to mute your microphone!
