City Congregation, the Humanistic Jewish congregation in NYC, has posted this interview with Rabbi Miriam Jerris, who leads the Society for Humanistic Judaism, explaining how Yom Kippur “works” for those of us who are Humanistic Jews. The SHJ has a video from Rabbi Jeffrey Falick, who is Rabbi at The Birmingham Temple, the first SHJ congregation, that also discusses it.
If you fast, I wish you an easy fast. And, in any event, I wish you a meaningful, constructive Yom Kippur.
They are short videos; give them a watch.
