I just finished reading a book with the actual documents, interviews and investigations on Fatima.
Even in the book it states that the reader will end up with some concerns.
According to Lucia, the Blessed Mother told her that their friend, Amelia, would be in Purgatory until the end of time. if that’s the fate of a child, what hope is there for the rest of us?
The “end of time,” was not said by the Blessed Mother according to the interviews the children gave to the various investigators.
The “end of time,” clause wasn’t mentioned until Lucia’s fourth manuscript, when she was a nun.
Another is that most people go to hell. The Blessed Mother did not tell the children this. Again, Lucia doesn’t mention it until later in life.
It’s also stated that Lucia suffered extreme scrupulosity as an adult and some of her statements must be taken in that context.
