Father Amorth tells us how to invoke and pray to the Angels

Who are the Angels? Father Amorth replies ...
They are our great allies, we owe them a lot and it is a mistake that we talk so little about it.
Each of us has his own guardian angel, a faithful friend 24 hours a day, from conception to death. It unceasingly protects us in soul and body; and we mostly don't even think about it.
We know that nations also have their own particular angel and this probably also happens for each community, perhaps for the same family, even if we are not sure of this.
However, we know that angels are very numerous and eager to do us a lot more good than demons try to ruin us. Scripture often speaks to us about angels for the various missions that the Lord entrusts to them.
We know the prince of angels, St. Michael: even among the angels there is a hierarchy based on love and governed by that divine influence "in whose voluntate is our peace", as Dante would say.

We also know the names of two other archangels: Gabriele and Raffaele. An apocryphal adds a fourth name: Uriel.
Also from Scripture we derive the subdivision of the angels into nine choirs: Dominations, Powers, Thrones, Principalities, Virtues, Angels, Archangels, Cherubim, Seraphim.
The believer who knows that he lives in the presence of the Holy Trinity, or rather, has it inside him; he knows that he is continually assisted by a Mother who is the same Mother of God; he knows he can count on the help of angels and saints; how can he feel alone, or abandoned, or oppressed by evil?

Invocation to the Three Archangels

Glorious Archangel Michael, prince of celestial militias, defend us against all our visible and invisible enemies and never allow us to fall under their cruel tyranny.

St. Archangel Gabriel, you who rightly are called the power of God, since you have been chosen to announce to Mary the mystery in which the Almighty was to wonderfully manifest the strength of his arm, let us know the treasures enclosed in the person of the Son of God, and be our messenger to his holy Mother!

San Raffaele Arcangelo, charitable guide of travelers, you who, with divine power, perform miraculous healings, deign to guide us during our earthly pilgrimage and suggest the true remedies that can heal our souls and our bodies. Amen.

"O God, who calls angels and men to cooperate in your plan of salvation, grant us pilgrims on earth the protection of the blessed spirits, who stand before you in heaven to serve you and contemplate the glory of your face".

ejaculation:
"Holy Guardian Angels preserve us from all the dangers of the evil one"
