Modern Jewish couples increasingly turn to rabbis for marriage guidance, yet these religious leaders find themselves caught between ancient traditions and contemporary relationship dynamics. As marriage evolves from a communal institution into a matter of personal choice, rabbis occupy a distinctive position at this cultural intersection. Drawing on frameworks contrasting traditional institutional marriage with modern pluralistic approaches, this research analyzes how the deinstitutionalization of marriage affects Jewish communal continuity and the rabbi's counseling role. The methodology examines marriage both as a social institution rooted in Jewish tradition and as a relationship shaped by individual choice. Through analysis of three primary counseling approaches—psychoanalytic dynamic theory, rational therapy, and conjoint therapy—the research reveals that rabbis' unique position in consecrating marriages is compromised by inadequate formal training, time constraints, and potential value conflicts. Six problematic marriage motivations emerge as critical warning signs for rabbinical counselors to identify. While rabbis can serve as vital pre-marital and marital counselors, effective guidance requires specialized training, clear referral protocols for professional therapy, and the ability to harmonize traditional Jewish values with contemporary relationship approaches. Enhanced educational preparation and ongoing professional development prove essential for rabbis to effectively support couples navigating modern marital challenges.
