The old “you will know him by his fruits” argument. Unfortunately, Fr. Maciel also preached an extremely orthodox message and the Legionaires of Christ recruited many orthodox young men to become excellent priests. Unfortunately, Maciel turned out to be a monster who predated on young men, had mistresses who had children and then had sex with his own children. Fr. Maciel was an excellent fundraiser, and created a religious empire of sorts. But look what damage he left in his wake?
Of course, Fr. Corapi has done none of these horrible things, though the money raising is one similarity, as is the John Paul II link. But to blindly support him based on his orthodox preaching and ignore his other, current actions, is foolish.
At this point, I could care less if he had sex with women or did drugs. What I am concerned about his is cult of “fans” and the division he is creating in the church. I care about the scandal he is causing (if he hadn’t spoken publicly, none of us would ever know about the letter this woman wrote - unlike Fr. Corapi, she wrote it to the bishop and never made it public nor attempted to clear her name when Fr. Corapi accused her of being crazy, a gold-digger and an acute alcoholic.
As others have mentioned, his rants are disjointed, contradictory and sound very strange. He speaks badly about the bishops and allows his “fan base” to call the bishops devils.
