Belief in angels is widespread.  Would it surprise you to learn more people believe in angels than believe in global warming or climate change?  In this episode of Religion Today, host Martin Tanner explains what or who angels are, where they come from and what their purpose is.  Many people, even some who do not consider themselves to be religious, say they have seen an angel who gave them direction, help or a warning.  Belief in angels is far more common than most people imaging.  Well over half the population in the United States, for example, believe in angels.
