Dr McAll succinctly relates a series of stories of his work in prayer healing for those suffering from oppression from dead relatives who's souls have not been laid to rest.
Drawing heavily from his rich and varied experience, he dedicates each chapter to various ways in which persons can suffer not just from sin, but even mental illnesses can have, though by no means necessarily so, its origin from their ancestors who have yet to be prayed for. He relates his experiences of how through pray, the celebration of the Eucharist, or having a communion of remembrance can lay their souls to rest, and how all manners of psychological issues have been healed. He retells stories of those who suffered from relatives who were aborted, those who committed suicide, those who engaged in occult practices, who never received a proper burial nor prayers after their repose.
I would highly recommend it for those who are concerned about the current state of mental health, to understand a traditional Christian view of the crisis. I would also recommend it for those Christians who do not practice, or perhaps do not even believe, in praying for the dead.
I leave it at 4-stars (I wish it could be 4 1/2) for the sole reason that Dr McAll leaves wanting much in the way of theological or scriptural support. Whilst he does touch on these, I felt that he could have said much more about it, though I appreciate this was largely a relation of his own experiences, an empirical and practical verification of the practice of praying for the dead, rather than a theological treatise on the topic.
Overall, I would consider it to be incredibly important material in the modern day, not only considering how prevalent mental health issues have become, but also the prevalence of the occult which may be disturbing those around us in ways we cannot understand.
