Over the centuries, many Roman Catholics (as well as those in other Christian denominations and other faiths) have developed a devotion to angels, those purely spiritual beings who preceded the creation of humans and serve as our protectors and as messengers from God to us. Special devotion is given to the four angels who are spoken of in Scripture: - Saint Michael the Archangel, who is the leader of the angelic hosts against the forces of evil. - Saint Gabriel the Archangel, who brought the news of the Annunciation to Mary of Nazareth. - Saint Raphael the Archangel, who accompanied young Tobias on his trip in the Book of Tobit. - Our Guardian Angel, who protects each of us during our entire lifetime from birth to death. Here is a collection from a variety of sources of prayers, litanies, chaplets, novenas, and other devotions to each of these angels, compiled by Luis Valverde and accompanied by magnificent classical images of each of the four angels. These prayers are meant for both individuals and groups and can be used in many situations and for many purposes. Saint Michael can be invoked for his intercession with God in our fight against temptation and evil; Saint Gabriel for our struggle to understand and do the will of God; Saint Raphael for companionship and safety on our journeys; and Our Guardian Angel for protection, especially of children, and for a happy death.
