A few groups, notably the Temple Institute and the Temple Mount Faithful, have petitioned the Israeli government to rebuild a Third Temple on the Temple Mount and restore sacrificial worship. The Israeli government has not responded favorably. Most Orthodox Jews regard rebuilding a Temple as an activity for a Jewish Messiah as part of a future Jewish eschatology, and most non-Orthodox Jews do not believe in the restoration of sacrificial worship at all. The Temple Institute has been constructing ritual objects in preparation for a resumption of sacrifices.
