Spirits Unveiled is an in-depth study of angelic beings, ghosts, and demonic entities and the deliverance from such spirits. The book engages angelology and demonology to examine the mysterious realm of the spirit world.

In Spirits Unveiled, Manning calls attention to the harmful tactics used in the deliverance ministry, such as binding and loosing, generational curses, and false doctrines concerning sickness, while shedding light on demons and deliverance. Spirits Unveiled investigates Hellenism, Greek thought, and the exile to Babylon that affected ancient Judaism concerning angelic spirits and demons. Read the entire series Unmasking the Unseen to examine doctrines that have evolved.
