Should bishops refrain from criticizing each other in public?
Dolan's courtesy to a sitting president on the call was not an issue. That the call got Zoom Bombed by other bishops was. Opinions on legal abortion demand public airing. The USCCB Pro-Life Activities staff is captured by GOP partisans, as are some of the bishops. Debate on this needs to be public in both Catholic and political circles. How bishops are selected is also part of the problem. Bishops elected by pastors and deacon administrators (lay ones, no clergy) could not get away with such non-sense. We are beyond the point when theological dispute by elected pastors is blood sport (like it was in the 4th Century). Episcopal opinion is just that, opinion. Truth stands on its own in argument, not by authority.
