This week, we are proud to bring you our interview with Eliana and Rabbi Doctor Professor Ruth Langer. Professor Langer is a liturgy scholar and director of graduate studies at Boston College's Theology Department. We explore how liturgical change gets squashed, how the Talmud set the course for future liturgical halacha, and how prayers emerged throughout history.  What is the value of knowing liturgical history to the pray-er?
