Which book?
I read the entirety of the (available excerpts of) "Orthodox Christianity and the English Tradition" as soon as you linked it, several days ago.
I have also been diligent to read the above-linked Article and supporting evidence on the Saint Nicholas Russian Orthodox site.
If I have otherwise missed some article of study you should like me to consider, it is not intentional on my part. But (if it is not inconvenient) please direct the matter to my specific attention in your next post. (I have read several Links, and am not sure which one your question concerns -- honestly, no offense).
best, OP
