GUARDIAN ANGEL ICONS
The Church, both east and west through God's revelations in both the Old and New Testament, teaches that each of us has Guardian Angel. One who stands for us before the face of God. Our Guardian Angel is our companion in life, our spiritual "kin" - alerting us of evil and directing our thoughts and actions to the will of God. Our Guardian Angel will stand with us on judgment day.
In the Slavic Eastern Christian traditions, your birthday is called your "Angel Day." That is the day you received your "guardian angel" who is with you everyday and will defend you on the last day.
In the Western church the Feast of the Guardian Angels is Oct 2nd.
