Heres some info, kinda more than what you wanted to know :
There are 9 celestial choir of Angels : Seraphim, Cherubim,
Thrones, Dominions, Powers, Virtues, Principalities, Archangels, and Angels.
According to Magdalen of the cross, all Angels posses the same happiness. The knowledge of God, is present to different degrees amongst diff Choirs. So a higher choir would posses more. St Gabriel, excel all other angels.
Angels dressed in red & wearing a small crown are assigned to persons who suffer. Those dressed in white with a beautiful crown, are assigned to innocent souls.
Children have very beautiful angels dressed in light blue with pearls , with a crown of roses. Angels of sinners are dressed in deep red, with their arms folded across their breasts, faces turned towards heaven in an imploring manner.
Holy souls who have a special mission on this earth have extraordinary Guardian Angels.
Padre Pio was one of those souls. So Padre Pio’s angel was special in the sense that it would have all the different attributes.
Angels can fly, guide or protect you, take messages across, be mechanics, drivers, translators etc. They will obey you and do what is asked, as long as it doesn’t oppose the will of GOD.
I have also read somewhere, that during Holy Mass the Angels pick up the minute particles of the Eucharist that have fallen and put it back in the Chalice. During elevation, every Angel present, will kneel and bow down. If only we could see this it would be so beautiful.
It’s sad that too many of us are not aware or conscious that they are besides us, ready to do pretty much anything.
Much of what I’ve written isn’t my own, its from the book “Send me your guardian angel” Padre Pio by Fr Alessio Parente. Padre Pio had a unique and deep relationship with his guardian angel. He would frequently send his angel on missions for needy souls. This book is about this relationship with his angel and encounters with others. It is very informative, beautiful stories. You will get a better understanding of what a fantastic celestial being God has given us to help us here below.
