The Occult Among Us by Charles De Fraune

"Those in a state of mortal sin, who have refused or have broken from the easy yoke of the Gospel, are in a state of spiritual bondage to Satan at the moment of death. As a result of this, they are led captive into perdition and eternal suffering in Hell. This is how we are damned; by leaving the passing realm of this mortal life without the fortification of sanctifying grace."

(pg. 91)
