Archbishop Marcel Lefebvre who claimed to be passing on what he received, and ordained four bishops without the authority of the Holy See. Apart from this act of disobedience, which he claimed was a necessity, he claimed to have denied nothing of the Catholic faith.
Fr Peter Kennedy, the parish priest of St Mary, South Brisbane, Australia who baptises, not In the Name of the Father, and of the Son and of the Holy Spirit as Our Lord told us to do, but in the name of Creator, and of the Redeemer and of the Sanctifer, hundreds of these baptism were declared invalid by the Holy See. Fr Kennedy also blesses homosexual unions, opens his Church to a Buddhist prayers, states publically his lack of belief in key scriptural doctrines such as the Virgin birth, the Resurrection of Christ and Life after death.
As Fr Sean suggests this is actually a crucial question, that is at the heart of the Benedictine papacy.
For the last forty years, in one way or another, to a greater or lesser degree, we have been following Fr Kennedy's course and decrying Archbishop Lefebvre's. The question today is, should we? This is ultimately what is behind the furore over the Williamson business, and the squeals and noise from the Catholic left at the possibility reconcilliation of the SSPX.
If you can answer this question, then the next one is: What is they way future?
