I read his Only Begotten years ago and there are almost 1,000 footnotes in the book; I was impressed with the read, but that was twenty years ago. The man quotes Migne in his talks. To be honest I have the Catholic Digest but have only perused it. Much of the Digest as I recall are quotes from the saints. I always consult the traditional copies of Denzinger if I need to. Mike realized at the age of 10 that he needed to become Catholic. He must have some wits about him. He took seriously the dogma Extra Ecclesiam Nulla Salus, which is more than I can say for a great number of traditional Catholics. I remember he said in his talk that Fr. Feeney converted nearly 100 Jews and that he had personally verified all of the stories. He was either not telling the truth or embellishing, but I have no reason to disbelieve him.
