I think that is the longest sentence that I have ever seen!!!
He did a good job though. : )
Yes, it is long, but only one, and not complex, which could easily be split up (next time maybe). And as you might know, i usually write with many short paragraphs.
But as a RC you should be used to long sentences. Just one of the many examples of the plethora of papal prolixity, is an encyclical (QUADRAGESIMO ANNO, POPE PIUS Xl ,MAY 15, 1931) of over 20,000 words, with more than one paragraph of over 400 words, and at least one sentence of over 90 words!
Still, WP says, "Jonathan Coe's The Rotters' Club appears to hold the record at 13,955 words."
