Well the current situation at St. Anthony's does guarntee this. The Chapel is owned by the board members and only the 1962 liturgical rite are to be used at the chapel. Novus Ordo will never be allowed into the chapel, and if the diocse even thinks that its going to attempt to bring Novus Ordo in, the board members can kick the diocese out.
This basic situation played out ten years ago with Our Lady of Fatima Chapel in Pequannock. The Chapel used to be Independent, but then in 1994 the FSSP was given permission by the Diocese to staff the Chapel. In the ten years which Our Lady of Fatim has been under the diocese of Paterson, Novus Ordo has never reared its ugly head at all, and it never will as far as I'm concerned.
That's good news. A chapel I know of here in Florida is in conversations with the diocese, but the diocese is unwilling to give them any guarantees, and there have been other chapels that seem to have been absorbed by dioceses basically in order to disband them. It's a pretty frightening prospect.
I don't think Fr. Perricone would permit it, either, and hopefully the Bishop is an honorable man and is not considering it.
