There is lot out there to read about angels. ‘Send me your Guardian Angel’ by Fr Alessio Parente (I hope I have got the authors name right) is a good book to read. It’s a small book with beautiful stories, including some info on the choir of angels.
Fr Alessio assisted Padre Pio in his old age. The stories are beautiful, some to do with Padre Pio and his Guardian angel. This book explains what a beautiful celestial being we have besides us to help and guide us daily.
One of the nice things I read was, when you cannot go to mass lets say because you are ill, send your Guardian angel to take your place. Another is, if you fall asleep while saying the rosary, your guardian angel finishes it for you.
I have often ‘lost’ my copy of this book, by lending it to others, where they have kept it for years, then when I find my book missing and can’t remember who I’ve given it to, I ask my guardian angel to bring it back. The book, has always returned ! My guardian angel has been a great help.
