Second paragraph -- "The grapevine has it that ... "

'Grapevine' seems to connote rumor. But what follows those words about what "many Catholics" have done, and continue to do, are far removed from rumors -- they are facts. 

Given the Catholic hierarchy's inability and/or unwillingness to adequately address the issues stated in that paragraph, I expect the exodus to continue unabated.

The "two-man show" is seemingly headed to a "two-person congregation", also.
