I believe you are incorrect. Mary was assumed into heaven, after she died. This is celebrated in the Catholic Church as the Feast Of The Assumption.
It wasn't dust who appeared to the three children at Fatima, I might point out.
Now where in Scripture is that found?
And which book and verse is that?
Don’t you realize that many of these anti-Catholics believe it was a UFO that caused “the miracle of the sun”, and that the “angel of light” that appeared to the children at Fatima was actually a demon? (Seriously. No sarcasm here.)
I doubt it was a real angel that appeared to Joseph Smith or
Mohammed, either. Satan can appear as an angel of light, only testing the spirits by the word of God can reveal truth or error.
