Judaism, Christianity, and Islam are recognized as the major religions of the western world, but it may be said they are not so much three separate religions as much as they are three distinct members of a single family of religious faiths. They are so related because they share the one foundation of a firm belief in monotheism. This common bond is no coincidence, since an undeniable link exists among them. Judaism, with its enduring belief in the one God of Abraham, Isaac, and Jacob, may be described as 'the mother of western religions,' as it became the parent not only of many of the ideas in Christianity but in much of Islam as well.
