I don't know Fr. Clifton but this letter indeed is very good and true.
A few more letters in the same spirit (opposing any Betrayal) from more European SSPX priests have been to Menzingen, some to Stuttgart. The answers from the high commands always were nonsensical.
Still these letters act as a retrieval of Archbishop Lefebvre's honour.
So, thank you dear truthful priests for writing them!
Indeed the SSPX is now being purged. And obviously it was high time.
The good ones go into the pot, the bad ones go into your crop!
