The Liberal Jewish community of Luxembourg as you see it today is only possible thanks to the constant strength, unwavering support, and the vision of some of the many people who have dedicated so much time into helping us grow and guiding us.
Rabbi Dr. Alexander Grodensky
Rabbi Alexander Grodensky was born in Dushanbe, Tajikistan, and grew up in northern Russia. He received rabbinical ordination from Abraham Geiger College (Berlin/Potsdam) in 2015 and an M.A. in Jewish Studies from the University of Potsdam. Before attending Abraham Geiger College, he studied in yeshivot in Russia and Israel and was a fellow at Paideia – The European Institute for Jewish Studies in Stockholm. During his rabbinical training he served as a student rabbi in Hamburg, Vienna, and Ridgewood, New Jersey.
In 2025 he completed doctoral studies at Hebrew Union College. His dissertation, “Divine Revelation and Human Knowledge from a Process Theological Perspective,” reframes revelation as an evolving, relational process shaped by divine persuasion and human perception. Engaging figures such as Moses Maimonides, Benedict Spinoza, Mordecai Kaplan, and Charles Hartshorne, the study explores the epistemological and theological implications of process thought for contemporary Jewish life and practice.
In addition to his training in Jewish theology, Rabbi Grodensky holds graduate degrees in Public Administration (Russian Academy of National Economy and Public Administration, St. Petersburg) and in Management (Lauder Business School, Vienna).
Rabbi Grodensky is a member of the Central Conference of American Rabbis (CCAR) and the General Rabbinical Conference of Germany (Allgemeine Rabbinerkonferenz, ARK). He chairs the Liberal Rabbinical Association (Liberale Rabbinervereinigung) and serves as Vice Chair of the European Union for Progressive Judaism (EUPJ), supporting emerging liberal Jewish communities across Europe.
He is actively involved in interreligious dialogue in Luxembourg and across Europe and serves as an advisor to the board of the Lutheran European Commission on Church and Judaism.
He is married to Isak Schneider.
