I believe Feeney+ was absolutely correct in his interpretation of EENS. I don't claim that his opinion was or is the ONLY correct one, I just don't believe he was wrong over against a more nuanced METHOD of presenting the doctrine. Fr. Feeney lived during a time when strident, confrontational 'preaching' was in vogue among the Prot heretics like Billy Graham and others. Fr. Feeney probably realized the effectiveness of unambiguous and bold statement-making during a time when sensationalism was becoming more common among influential public figures.
Fr. Feeney was, however, regrettably disobedient to his lawful superiors and to the Holy Father. There is no way that a faithful Catholic can accept Fr. Feeney's example of disregard for the Holy Office as reasonable or proper.
It's a shame that the irregularities and blatant defiance that were typical of Fr. Feeney's efforts will likely continue to cause people to ignore the true importance of EENS, all because the media-mad spin doctors have thrown around the word "excommunicated" without knowing or presenting all the facts.
Immaculate Heart of Mary, triumph soon!
Most Sacred Heart of Jesus, have mercy on us.
