The Bereans 

I did some research and I have to agree with you that it is only this Bereans website that is openly labelling Soriano's group as a cult. Who are these Bereans anyway? They are completely unnotable and I am yet to encounter anyone who actually belongs to this anti-cult group? Chances are they are also a cult group, or even a ghost religion (one that exists only in the Internet). I don't think that articles from the Bereans website qualify as reliable third-party published source as per WP:RS. If you remove all the Bereans references in the Ang Dating Daan article and replace them all with citation needed tags, we can probably remove all of those unsourced statements within a month's time. It is unfair to use critical quotes from websites of other religious organizations because of the obvious bias. Quotes should be either from notable newspapers, magazines and books (self-published books not included). As I will never use articles from Soriano's website(s) to criticize, say for example, the Baptist sect, I would also not use articles from a Baptist website to criticize Soriano's sect. The rules must be applied to all for the interest of fairness and equality. –
