The Torah, Quran, and Bible are all different versions of the same text. With the Torah just being the first 5 collections and the difference of the Quran and Bible being who wrote it. Largely the god they follow is considered to be the same one, different name and different chosen prophet. Christians believe in Christ, Catholics believe he was just a saint, Islam believes more in Muhammad, Jews believe in several prophets like Catholics. They’re abrahamic religions, based on the same events.
