What the author maintains accounts as well as any explanation for what are -- in the main -- observable facts. When you say "the Faithful," do you mean what some would call "the little ones" -- those Catholics of whatever age who have a simple faith and perhaps not too much sophistication about history, philosophy, etc.?
Frankly, I wouldn't worry too much. They're unlikely to read this or hear about it, and if they did, they wouldn't get too worked up about it -- IMHO.
In other words, I really think those who hear the hypothesis and grasp the implications will have the inner resources to deal with it. Those who don't have the resources will likely never know.
