Messianic Judaism is a movement of Jews who believe that Jesus (called by them with his Hebrew name "Yeshua") is the Jewish Messiah, and who perform this belief in a Jewish way (observing the regulations of the Torah etc.). They are called "Messianic Jews". The main branches of Judaism do not consider Messianic Judaism to be Judaism, but rather a form of Christianity, because Judaism rejects Jesus/Yeshua as the Jewish Messiah.
