When Fr. Gruner attended the SSPX Winona Ordinations around 2009, afterwards, he spoke to an informal group on the grounds of the seminary.
The "Two Sister Lucy's" topic came up and Fr. Gruner was overheard to say, that he refused to publish anything on the theory because it would scandalize his Novus ordo benefactors.
This was the first time I started to doubt the credibility of the self-proclaimed "Fatima Priest".
It would be interesting to know if the SSPX has taken over Fr. Gruner's CFN newspaper and the Fatima Center?.
Many SSPX associates (Fr. Albert, Fr. Philipson, etc) have been seen "on stage" at the latter recently.
Of course, if it's true, why would Bp, Fellay want to keep it secret? I think we know the answer.
