When it comes to message work and readings, mediums sometimes receive information that they should think twice about before letting it out. Here is an article about a medium in the UK who didn’t do that, and does not understand why she’s been ousted from her Spiritualist church.
Mediumship is about respect, confidentiality, and integrity, and not just blurting out whatever you’ve received as “the truth”, regardless of the consequences, especially in a public setting.
Mediumship has an ethical component to it, whether you are aware of it or not, and whether you acknowledge it or not. I would say that she’s not aware of it. Let’s hope she learns, before she hurts anyone else.
