Reference to the archangel Gabriel occur in Judaism, Christianity, and Islam. At various stages of their histories, the intervention of the archangel Gabriel is associated with a crucial phase of the development of that religion. Emphasis will be placed on the Sacred Scriptures of those religions, as well as extra-biblical documents such as legends, lore, and iconographical representations. This data will be analysed in order to examine why it is the same angel that associated with all the three religions, leading to an examination into the origins of the root of the name Gabriel, in the apocalyptic context of a divine intervention bringing hope and reassurance, and announcing the coming battle between the forces of good and evil.
