This is for Mikey to answer but I'd like to offer the following for your consideration, David. This is an issue that has divided even those who are much persuaded by the guidance of teacher, Silver Birch. As things began to look ominous in the period before World War, 2 Silver Birch was asked in one of his regular seance Q&A sessions whether war would break out. His answer was no and we all know how wrong that answer was! It's been argued the ideas of his medium, Maurice Barbanell, had colored SB's 'channeled' communication over this point leading to a wrong 'prediction'. You have to judge for yourself whether this guide could have been wrong or whether there was coloration of his message by the medium. My personal approach is that no spiritual guide is omniscient and that we should always exercise caution when listening to guidance from any of them, accepting only what does not offend our reason. That doesn't mean we think they're wrong about certain issues but only that we're not confident they're right. That approach is one which could reasonably be applied to all mediumistic ('channeled') communication.
