Rabbi Mordechai Fischer is addressed in correspondence from the Lubavitcher Rebbe as a rabbi serving a Jewish community, approached for guidance regarding participation in interfaith events.
The Rebbe responded to Rabbi Fischer's inquiry about whether he should participate, as the community rabbi, in a Brotherhood Week event alongside a Christian clergyman, with the gathering taking place in a room within the church building. The Rebbe firmly advised against participation, citing both halachic prohibition and the issue of mar'is ayin (appearance), emphasizing that observers might misconstrue the rabbi's involvement as an endorsement of equivalence between Judaism and Christianity.
The Rebbe provided Rabbi Fischer with guidance on how to explain this position to his lay leaders. He suggested emphasizing the value of religious freedom and liberty in their country, noting that such freedom means each faith should be able to maintain its distinctiveness without pressure or confusion. The Rebbe illustrated the importance of unwavering commitment to Jewish faith and practice, even in seemingly minor matters, drawing on examples from Torah and Midrash to stress the potential spiritual harm of blurring religious boundaries, especially in public settings.
The tone of the letter is respectful and supportive, offering practical advice and encouragement for Rabbi Fischer's leadership of his congregation in accordance with Torah values and yiras Shamayim (fear of Heaven).
