This statement needs correction:
Prior to his death, Father Feeney was presented with an offer to get out of his invalid excommunication by the schismatic Novus ordo Church.
He was required to recite the "Apostles Creed" which he already prayed on a regular basis.
The excommunication and lifting of the excommunication were both fraudulent, newChurch events.
No, the excommunication happened in 1953 under Pope Pius XII so regardless of the validity (or injustice) it was certainly not a “newChurch” event. Also regardless of whether the lifting of the excommunication was a “newChurch” event or not, it was valid because Fr Feeney believed they were legitimate authorities of the Church and he showed his sorrow for having been disobedient to Church authority which is what he was specifically excommunicated for. So he certainly died in the Church and he was never excommunicated for his theology. In cases where there is common error regarding jurisdiction the Church supplies. The lifting of the excommunication is a perfect example of that.
