This communication examines the religious legacy and influence of Lily Montagu, founder of the West Central Liberal Synagogue in England, through the reflective analysis of Rabbi Roger Pavey, who served the synagogue for six years following his ordination at Leo Baeck College. The study employs participant observation methodology and retrospective analysis to assess Montagu's dual impact on Jewish religious life. The investigation reveals two primary findings: a negative assessment of Montagu's contribution to Jewish tradition, characterized by limited Hebrew knowledge and adherence to Classical Reform Judaism under Rabbi Israel Mattuck's influence, which resulted in a form of Judaism described as "Unitarianism derived from Jewish sources" lacking halakhic framework; and a positive evaluation of her profound personal religious faith and charismatic spiritual influence on young Jewish women through the West Central Jewish Club and synagogue activities. The analysis concludes that while Montagu's specifically Jewish contributions were minimal due to her radical Reform orientation, her integration of deep personal faith with Jewish communal expression created a transformative religious model. The study suggests that contemporary Judaism risks undervaluing the importance of personal religious faith and could benefit from understanding Montagu's synthesis of individual spirituality and collective Jewish identity.
