<<(The Aruch Laner.)>> Binyan Zion [responsa].

An important work of responsa. One responsum of particular interest is #63, to R. Abraham Ash of New York, dated 1858, regarding whether it would be halachically acceptable for the Beth Medrash of New York to utilize a former church rectory as the synagogue's sanctuary. Another groundbreaking position in this work is the identification of non-religious Jews with the Talmudic label ‘Tinok SheNishba’ (see Responsum #23). This is the first time in history such a parallel was drawn, and R. Ettlinger’s position would become widely accepted across much of the Orthodox world.
