 The core of supersessionism, in which the Mosaic Covenant is canceled, is less agreed upon.Though the mitzvot may or may not be seen as necessary, most are still followed, especially the keeping of Shabbat and other holy days.All Messianic Jews hold to certain eschatological beliefs such as the End of Days, the Second Coming of Jesus as the conquering Messiah, the re-gathering of Israel, a rebuilt Third Temple, a resurrection of the dead, and many believe in the Millennial Sabbath, although some are Amillenialist.
