Since its destruction in 70 AD, the desire to rebuild the Temple has represented the fulfillment of Jewish messianic hopes and expectations. Over the generations, the rabbis made many restrictions on human action to make the messianic dream alive. This paper describes the internal debate within Religious Zionist circles in Israel today over the question of Jews entering the Temple Mount and taking action to rebuild the Temple. It presents the internal religious dynamics from passive to active that permitted Jews to enter. It presents the positions of the Mercaz Harav Yeshiva, one of the most important centers of modern-day religious Zionism, whose leaders reject the idea of Jews entering the Temple Mount in the current era. The article further describes the debate on the question of entering the Temple Mount within the Israeli Chief Rabbinate, whose plenum strongly negated such a possibility, although some leading members of the Rabbinate permitted entry and prayer in an individual capacity. This is followed by a discussion of the decision by the Committee of Yesha Rabbis permitting Jews to enter the Temple Mount, under certain Halachic restrictions, and of the debate their decision evoked among Religious Zionist rabbis. The article continues to discuss how, since 2013, barriers have lifted and masses of people visit the Temple Mount, praying on the site, while a growing number of politicians call for a change in the Status Quo on the Mount. The article ends with statistics about the public opinion of Israeli Jews regarding visiting, praying, and building a Temple on the Temple Mount.
