Rome invited the sspx only for discussions. They didn't invite anyone from Cmri, or PV, or anyother. I can't speak for Rome but I have notice my local novus ordo dioceses where there has been a huge push towards modernism by wanting to make Pope Paul VI a saint inorder to further promote vatican II.
Churches and schools are still closing on east coast usa, and still no one wants to admit that vatican II is a failure.
Also, power must be restored to the Pope instead of US Conference of Catholic bishops...
