The Angels by Fr. Pascale Parente
Father Pascal Parente compiles in this little book nearly everything that is known with certainty about the angels. Drawing heavily from Tradition and Doctors and Fathers of the Church, Parente explains the angels' creation, intelligence, free will, language, powers, movements, number and particular duties. He also relates the history of devotion to the holy angels and discloses the little-known fact that there are guardian angels, not only of individuals, but of churches, dioceses, and nations!
