In this chapter we have a little analogy that is kinda like the blind men and the elephant. There are different bees looking into a church through a stain glass window. The bees then argue and form groups and say that their perception of the inside is right, and this is why there are different religions. That are all looking into the same building, their perspective is just a little off and the poor bees are unable to truly know what the inside is really like.
This is pretty much pluralism. It negates what is core about religions and does a bad job at even affirming common ground between the religions. Pluralism itself assumes that it's perspective is the right one based off some special knowledge that no one else has access to. It then logically has to assumes that all religions are wrong.
Also I already quoted page 29-30 of this book which has the old man agreeing that you can't have all religions looking into the same room as at the core they are different.
I agree with the idea that the bees (us) are unable to sit around and speculate who God is. To assume we are right about our own speculation shows a lack of discernment in our own thinking and would result in nothing (to paraphrase Isaiah). We need to be told who God is, we can't just invent him.
