I used to watch Beroean Pickets quite regularly, and generally found Eric Wilson calm, reasonable and honest. I've not looked at his material for quite a while though, and I don't particularly intend to dive into this row either. But again, it does show the danger of putting too much trust in "mortal man in whom there is no salvation".
It's always instructive to see how someone reacts to an accusation. Recently in the UK, we've had a well-known TV personality accused of making sexual advances and offensive comments to female guests on his programme. His response was, in part, to say that his critics were all "middle-class women of a certain age" - hardly the statement of someone who is contrite or is humble in defending himself. Again, it was a dispute I hadn't followed closely and I had no personal view of the celebrity concerned either way, but hearing his choice of words in defence instantly made me suspect the accusations were fully justified.
As regards jumping from one "cult" to another, I think these words are apt:
Jesus answered: Watch out that no one deceives you. For many will come in my name, claiming, 'I am the Messiah,' and will deceive many [...] and many false prophets will appear and deceive many people. [...]
At that time if anyone says to you 'Look, here is the Messiah!' or 'There he is!' do not believe it. For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect."
