The Holy Guardian Angels

 The concept of an angel assigned to guide and nurture each human being is a development of Catholic doctrine and piety based on Scripture but not directly drawn from it. Jesus’ words in Matthew 18:10 best support the belief: “See that you do not despise one of these little ones, for I say to you that their angels in heaven always look upon the face of my heavenly Father”

Devotion to the angels began to develop with the birth of the monastic tradition. Saint Benedict (July 11) gave it impetus and Saint Bernard of Clairvaux (August 20), the great 12th-century reformer, was such an eloquent spokesman for the guardian angels that angelic devotion assumed its current form in his day.
