What Fr. Corapi describes is the standard inquisitional process (i.e. the court process) used by the Church for at least 1000 years. Every one of those six points accurately describes how every Catholic inquisition has always been run, except he's supposed to have the opportunity to list his enemies, so that their testimony can be discounted. Apart from that, he's pretty accurately describing his situation.
He's not leaving the Catholic Church, he's just leaving an absolutely untenable situation.
When Padre Pio was faced with a similar situation of baseless accusations, he simply accepted it: suspension for ten years.
Ten years of no public Mass, no hearing confession, no public preaching.
Fr. Corapi is obviously not Padre Pio.
