Interesting. What would you recommend for someone who would like to get into Catholic prophecy?
What you say about going to the source material first makes a lot of sense. People can't seem to agree on what a person "really" meant by what he said. This has been my frustration with history. So much of it only serves as a tool to promote one agenda or another.
For what little it's worth, hmm, I think for a beginning you might consider for yourself some of the following books. I wouldn't choose simply one, what flaws one has, will then be balanced out by the other and the prayerful discernment necessary. This isn't an endorsement but these are some of the likely best possibilities for you to consider because of all the sources quoted and general use.
Yves Dupont, 'Catholic Prophecy'
Rev. Culleton, 'The Prophets and Our Times'
Desmond Birch, 'Trial, Tribulation & Triumph'
The last book is the newest and I think one that gets folks comfortable with prophecy who aren't to some degree, for what it's worth.
I prefer recommending books entirely by saints but in response to your question the above, may you discern which may be good and may they do you good I pray. I have read of each of them but not entirely another reason why I hesitate.
