Angels help Christians achieve salvation in countless ways, no service is beneath them. They carry the prayers to the Divine, they offer strength, and comfort to the faithful.
The Christian belief and many other religions, place the creation of Angels before mans, although there is no exact way of determining the time of their creation.
The term "Angel" is used specifically in Western religions to distinguish benevolent spirits from malevolent spirits (also called demons).
It is applied to a form of spiritual being who mediates between the realm of the Divine and the world of mortals. This description of "Angels" refers to their function rather than to their being or nature.
