Messianic Judaism is a sort of blend of Judaism and Christianity, with the biggest distinction being that Messianic Jews recognize Jesus as the messiah. Messianic Jews are often referred to as a sect of Christianity, but many consider themselves to be a sect of Judaism, particularly because many of them are ethnic Jews, born into a Jewish family. I have a Messianic friend who notes that it might be best to refer to them as Messianic believers. They believe they are saved by grace, but still practice many of the Old Testament or Jewish laws, such as maintaining a kosher diet. They recite the Shema and several other traditional Jewish prayers, but they also have their own Siddur, which contains prayers that reference Jesus as the Messiah.
