I think “prophecy” is really just a snazzy term for “divination,” as the latter sounds a bit too “magickal” to religious JCI individuals. It’s possible for anyone to have visionary glimpses into the future with magick, and in-fact there are some spirits that specialize in giving you these.
One thing that a lot of the visions in texts such as the book of Revelations, the Book of Enoch, and Dee & Kelly’s spirit diaries, the visions commonly termed “prophecies,” have in common though is that they all predict events to occur relatively far into the future, and they do so in rather abstracted ways.
I’ve had a good number of visionary experiences in ritual, and most of the more divinatory ones show me in some place doing something at some point in the future, and these are often accompanied by how I would feel about that future, and intuitions/advice on how I may go about getting there. If you look at these prophecies, however, they are often much heavier in symbolism, and tend to have a much broader scope than just the individuals involved.
I think one thing to keep in mind when contemplating these visions though is that just like any other form of divination, nothing is set in-stone, and that the individuals who received the prophecies had them filtered through their own worldview.
For example, there’s one in the Book of Enoch telling of a time when Raphael would come to the earth and bind Azazel. To my interpretation, Raphael was not binding him, but coming to work with him, in harmony. The binding interpretation stinks of religious “angel good demon bad” thinking, in my opinion. Makes more sense that way anyways - Azazel brings the war, and Michael protects the ones who shouldn’t be hurt (and likely does his fair bit of warring as well, Four Horseman anyone?), while Raphael heals up any unwanted collateral damage.
To answer your question then, if we define “prophecy” as being synonymous with “divination,” then yeah prophets should be able to help with anything that a tarot reader could, assuming that they are skilled enough. If we want to say that prophecies are a more specific kind of divination, then it seems like prophetic visions are given to individuals who work very deeply with the angels.
Speaking of, this reminds me of a cool vision Tzadkiel gave to me over the summer. I was on a yacht with a bunch of occultist friends, and we went out to a private island and did a bunch of rituals together. I don’t know why we had to go to an island for that, but I’m not gonna complain about a free yacht ride (well, unless it was my yacht, in which case hell yeah for wealth magick).
