There was some sort of dispute over his book, "Exorcism and the Church Militant." First he gets removed as president of HLI, and soon after his book is discontinued, which Human Life International owns the copyright on.
It's an extraordinary book written for priests to learn about exorcisms. Also a great book for lay people to find out more about the rite (I'm currently reading it).
If you pen an excellent book regarding the removal of Satan, you're going to get some flak (from Satan!) in one way or another. Same thing happened to Michael D. O'Brien when he wrote a book asking parents to discern Harry Potter and Twilight.
So I think it has to do with the book he wrote. Could be wrong. Wouldn't be the first time, but
I'm praying for him very much.
So HLI showed him the door? I was under the impression that he resigned voluntarily.
That puts things in a slightly different perspective.
In a word, politics.............personalities, egos, policy disputes etc etc.
The usual petty stuff.
