Devotion to the Nine Choirs of Holy Angels

Devotion to the Holy Angels, widely regarded as the most popular work of Rev. Henri-Marie Boudon, is a powerful call to rediscover the living reality of the angelic world. With clarity, simplicity, and spiritual depth, Boudon urges the faithful to cultivate a deep devotion not only to their guardian angels but also to all nine choirs of heaven. First translated into English in 1869, this work presents a theology that is both accessible and firmly grounded in the tradition of the Church. The angels are revealed not as distant symbols but as active participants in the spiritual life—protectors, guides, and defenders appointed by God. Boudon highlights the consequences of neglecting the supernatural order, showing how a disregard for the presence of the angels leaves souls vulnerable. This work stands as both a warning and an invitation: to take seriously the unseen battle for the soul and to confidently call upon the powerful assistance God has already provided.
