The RC Church is who declared it to be a credible apparition, so you go first. What’s the proof that it WAS Mary? Because it said so?
Mary’s dead, friend. And if she trusted in Jesus Christ alone for her salvation, she is in heaven with him now.
That wasn't the question I asked you, T minus four. I didn't ask about what the Catholic Church thought about the events at Fatima, or what evidence they used to confirm them as genuine (unlike other "Marian apparitions" that have occurred since that time; i.e., early 20th century).
I was asking about your view of the matter, which I suspect has been informed on grounds other than direct evidence, logic, or reason. And from "outside" the Catholic Church and its historical traditions. [Probably meaning that you would hold any evidence produced by the Church as "suspect," prima facie, a priori.]
You wrote: "Mary’s dead, friend. And if she trusted in Jesus Christ alone for her salvation, she is in heaven with him now."
That's a pretty drear and dread statement, my friend, though it is not false. But where is the Holy Spirit to help such a person, who could say such a spiritually attenuated, deadly thing? Mary doesn't "reduce" to a "select" doctrine. And neither do we; for like Mary, we are flesh and blood — and Spirit.
