Last Thursday Raymond Arroyo of EWTN had an interview with Cardinal Burke, one of the Four Cardinals, in which the Cardinal explains what is at stake. Here is the ending of the interview:
Cardinal Burke: Of course it does, that [is the] standard instrument in the Church for addressing such a situation. Yes, there are other cardinals. I don’t want to get into this business of the numbers. We have to remember, the criterion here is the truth. There have been cases, for instance, take for example the case of Henry VIII and his desire to be able to enter a second marriage without having his first marriage declared null—all of the bishops of England except St. John Fisher went along with the error, but St. John Fisher is the saint because he defended the truth. And all of us in the Church who are cardinals, bishops, we have the responsibility to defend the truth; whether we seem to be numerous or we seem to be very few doesn’t make any difference. It’s the truth of Christ which has to be taught.
