There would be no Savior/Messiah without Judaism.

In Abrahamic religions, a messiah or messias (Hebrew: מָשִׁיחַ, romanized: māšīyaḥ; Greek: μεσσίας, messías; Arabic: مسيح, masîḥ; lit. 'the anointed one') is a saviour or liberator of a group of people. The concepts of mashiach, messianism, and of a Messianic Age originated in Judaism, and in the Hebrew Bible, in which a mashiach is a king or High Priest traditionally anointed with holy anointing oil. Messiahs were not exclusively Jewish, however, and the concept of 'the' Messiah as a single individual is a strictly post-Biblical tradition as it is not found in the Old Testament.
