Rabinovitch was a religious Zionist, a supporter of the settlement movement, and a vocal opponent of the Oslo Accords and the Disengagement. He was, however, often more liberal in social and religious matters than many in the religious Zionist movement. In an interview, Rabinovitch said that he backed religious studies for women, and did not see a problem in Halakhic decisions taken by women. Nonetheless, he signed a letter in 2019 agreeing with the Chief Rabbinate's opposition to religious Jewish women serving in the IDF. He also ruled that it is incumbent on Israeli combat medics and doctors to treat and save the lives of Palestinian combatants, even if wounded in the course of attacking Israelis. Rabinovitch characterized Christianity and Islam positively as movements that spread monotheism, morality, and messianic hope. In addition, Rabinovitch differed from many other religious Zionist leaders in that he did not view the State of Israel as a harbinger of the Messiah and argued for greater seperation between religion and state in Israel. Often his iconoclastic positions were deeply influenced not only by Jewish tradition, but by the core ideas of political liberalism as well.
