Tendler has written and lectured widely on medical ethics. He translated various medical oriented responsa of Feinstein into English, even though Feinstein expressly forbade such translations.Tendler advocates the theory that complete and irreversible cessation of function of the entire brain renders a person “physiologically decapitated”, and is considered legally dead according to Jewish law.Tendler asserts that once organ donation has been deemed permissible under the given conditions, it is indeed mandatory, falling under the rubric of the legal obligation of Jews to preserve the lives of others. In addition, Tendler has written extensively on euthanasia, infertility, end of life issues, organ donation, and brit milah (Jewish circumcision). Tendler has been a strong advocate for the use of a tube when performing metzitzah, suction of blood during circumcision. Serving on an RCA panel on stem cell research, Tendler expressed respectful disagreement with the Bush administration's position.
Tendler is the posek for the Association of Orthodox Jewish Scientists and its past president
May the merit of the tzaddik Rabbi Moshe David Tendler, protect us all, Amen.
