Lintup and his wife Slova (née Kantzapovich) had eleven children who survived childbirth. One of his sons, Tzvi Hirsch immigrated to the United States in 1905. Passing through Ellis Island, his name was changed to Harry Sebee Linfield. Upon ordination, he too became a rabbi. Lintup’s daughter Liba, married Binyomin Tzvi Movsas, who initially succeeded his father-in-law as rabbi in Birzai. Movsas later served as rabbi of the town of Krekenava until he was killed along with his family during the Holocaust. One of the Movsas’ children, Miriam, managed to escape, eventually settling in Cleveland, Ohio, where her husband, Eliezer Levi was "rosh mechina" (high school dean) at the Telshe Yeshiva. Lintup viewed the salvation of the Jewish people as inextricably linked to Torah study. He believed that knowledge of "penimiyut haTorah" (inwardness of Torah) contained the medicine for the spiritual malady of the generation. Both Lintup and Abraham Isaac Kook attempted, each in his own way, to disseminate Kabbalah to the masses and coming under criticism from their rabbinic peers for it. Philosophically, Lintup sought to synthesize the schools of Moshe Chaim Luzzatto, the Vilna Gaon and Chabad. He believed that Kabbalah in general, and "Tsimtsum" in particular, were not to be taken in a purely literal fashion, thereby placing himself at odds with other Kabbalists. Frieden has stated that his teacher was a Mitnaged (opponent of Hasidism) in spirit, though he was Rabbi of the Hasidic community in Birzai. Methodologically, Lintup was said to apply "halakha" leniently, which angered others. Yet when approached with complaints about Lintup’s methods, the Rogatchover Gaon responded "If I were not familiar with him personally, I would cut him off from the community, but I am acquainted with his honesty and his purity of heart and his great knowledge of Torah, and he has upon whom to rely if he is lenient in "halakha". Let him be." He further believed in leniency with respect to the spiritual practice of non-Jews with respect to adherance to the Noahide laws.
