Bishop Athanasius Schneider accepts invitations to dioceses only when the local bishop gives a written permission.
He says this in his interview book “Christus Vincit” which was recently translated from English into German, Spanish, French, Portuguese, Polish and Italian.
Schneider was rejected several times: in the USA, Germany and Austria. Once he was denied a permission with the claim that "he was against Pope Francis."
The rector of a shrine in Germany asked Schneider to celebrate a Pontifical Mass and to give a lecture, but the local vicar general refused permission saying that, “the diocese cannot give Bishop Schneider permission to celebrate a Pontifical Mass because his presence causes division and tension”. He added that the rector should “in future only invite bishops who are strong in the faith”.
Schneider asks back: “Strong in what faith? Perhaps in the Protestant faith of this vicar general?"
