I don't want to dismiss your concern, but you have to rule that out first. Many mentally ill have religious fixations or attribute auditory or visual hallucinations to ideas they can understand.
Next, talk to a priest or the local bishop. I'm Catholic so I don't know if Protestants can handle the issue.
I wish you and your family well.
Protestants can handle the issue. As believers, we are all indwelt with the Holy Spirit, and we have been given a priesthood by Christ through Christ. Demons have no power over you. You are not theirs. Command them to go in the name of the Holy Trinity.
Sounds like reasonable advice. I would want to cover all of my bases and deal with it on both the scientific and spiritual battlefronts. Prayers for your brother and nephew.
Unless mental illness is telepathic, that's not realistic.
This guy's son described the same thing he saw. That gives it a LOT of legitimacy in my book.
I'm presuming that the father never shared with him what he saw. There's no other way for the son to know it unless he saw it too.
Just wanted to echo what IrishCatholic said about checking out mental factors. Tweens & teens go through a lot of hormonal changes and it can trigger things such as schizophrenia that have not manifested earlier. (Not saying this is schizophrenia, just using that as an example.) OTOH, I do believe there are “more thing in Heaven and earth” than we are aware of. If my child came to me with that report, I would take him to the doctor first and get him thoroughly checked out, though I’m not sure I would tell them the whole story since you don’t want to get his file tagged with prejudicial terms at such a young age. I think I would just tell the doc he thought he had seen things a time or two that weren’t there, but not go into detail.
If that did not pan out, my next stop would be with my priest or pastor. And I’d tell him/her the *whole* story.
