What are Angels?

What or who are the angels? When and why were they created? What is their nature, what is their task, what is their relationship with people?
To these question, the Church, through the teachings of the Holy Fathers but also through the timeless experience of its Saints, is providing us with some discreet answers: useful and enough for our salvation, but not completely satisfactory towards our officious curiosity. What this means is that although the Church reveals to us many sides of the lives of angels, it keeps others secret inside the mysteries of the future age.
Subsequently, guided by Holy Scripture as well as the writings of the Holy Fathers, we will attempt an approach to the world of God’s holy angels. — Introduction
