Ruth Langer is a Professor of Theology at Boston College, and a noted expert on Jewish Liturgy and on Christian Jewish Relations. She is married to Jonathan Sarna.
Langer takes the position that the liturgy developed gradually and over many centuries and that during that period of development, when rabbinic authority differed from popular custom on questions of liturgy, the liturgy always followed popular custom. Langer’s analysis of the development of the Torah service is particularly widely noted.
Jewish-Christian Relations
In criticizing some parts of the Christian liturgy seen as anti-Jewish, Langer has explained that the Jewish liturgy does not include anti-Christian prayers.
