I think you are right. This also explains the resignation (if that is the right word) from priesthood. As a layman he gains the ability to speak out against the system. In fact, among his conferences that I heard on the radio was one where he came close to actually accusing the bishops of silencing good priests on the slightest of suspicion.
He's done that before. The sad fact is that he will no longer celebrate Mass as I see it...
I have a feeling it's a select group of bishops that are the worst offenders. Behind the scenes, they do have their own little cliques. The other thing to remember, is that at ordination, each new priest pledges fealty to the bishop and his successors. Corapi is an order priest. This was the only way they could shut him up -appeal to the order.
It's all very disturbing, but given some of the truly human issues involved (not the least of which is a certain amount of immaturity among some members of the clergy), not at all unexpected. We the laity are going to have to demand answers, I guess. And request that the clergy kindly grow up like those of us in the "real" world have had to.
