St. Thomas Aquinas claims that the air is full of angels. It is also full of demons.
Daniel 7:10 notes that there the number of angels is huge. We know that those angels which fell are traditionally, because of a line in Revelation, said to have been one-third of the number of created angels.
That makes a lot of demons.
Millions.
What is unseen is greater than what is seen.
Of course, if two-thirds of the angels stayed with God, there are more "on our side".
However, we are up against a enormous army of demons, all of whom are full of malice.
These creatures want us to be miserable like they are, and they also hate God, and all His creatures.
St. Jude in his epistle describes the fallen angels thus, 1:6:
And the angels who kept not their principality, but forsook their own habitation, he hath reserved under darkness in everlasting chains, unto the judgment of the great day. DR
Do not be foolish or imprudent.
Do not be presumptuous.
By the way, read the Epistle of Jude. It is a great read.
