Nifty little piece on how the Church weighs

…Marian apparitions.

If you want a full meal deal discussion of the fascinating problem of private revelation (of which Marian apparitions are one species), check out Chapter 3: Private Revelation, Marian Apparitions, and Sundry Tales of the Unexplained in Volume 3: Miracles, Devotion, and Motherhood from my Mary, Mother of the Son trilogy. (There’s also an Appendix which discusses the major Marian apparitions approved by the Church).

I’d order the whole trilogy if I were you since a) it’s cheaper than ordering each book and b) if you read Volume 3 without reading the other two, there’s a good chance you will miss a whole lot.
