Yes, this is a good move. Isn’t one of the key speakers there going to be McCarrick’s longtime roommate? And the Jesuit priest James Martin is it - time to reevaluate the Church’s position on homosexuality, etc. I read these no-shows by US bishops as kind of a message to the Vatican, ‘slow the progress train, please, just for a bit’. US and Europe at different places on the journey, going on different tracks.
I wonder if this crisis is not a very good thing indeed. It could lead to an organic distancing between the US Catholic Church and the Vatican. Elements of the US hierarchy gain the power necessary to take the steps to clean up the structural corruption, really clean it up - this would mean a major restructuring, reduction, exposure of institutions, individuals, etc. A nightmare for the press and Catholics, cleansing of the temple. The Bishop of Rome is increasingly sidelined in terms of policy, legal issues - adherence is a formality, much like the African Anglicans and the Anglican Church in England, America. Other regions follow the lead of the US in the next 50, 100 years.
Ironically it was Pope Francis who wanted this kind of openness, decentralization, shift of power to local bishops, a leveling of the Bishop of Rome, more like the Eastern model. He just may get it. This would organically break up a lot of the corruption at the top, the cliques. Save the Church when you get right down to it. I think a lot of the European Church, which is in much worse shape than the Church in the US, would love to see the back of the US Church.
