And Maria Valtorta has strong sponsorship;
His Holiness Pope Pius XlI, February 26 1948:
"Publish this work as it is. there is no need to give an opinion about its origin, whether it be extraordinary or not. Who reads it, will understand."

Multiple Bishops and Archbishops (one of whom is a Major Archbishop, Padiyara of Ernakulam, head of the Syro-Malabar rite) have written letters of approval for the Malayalam translation of the Poem. Among them include; Archbishop Gregorous of Trivandrum, Bishop Benjamin of Darjeeling, Bishop D'souza of Pune, Bishop Kundukulam, Bishop Kureethara, and Bishop Soosa of Trivandrum. Bishop Soosa is later promoted to Archbishop by pope John Paul II
In general I think I can agree about charity running cold among Catholics. We sometimes go too far in trying to correct others and not far enough in building up the good things. But that's really cheap to bring up the moment such a controversial set of topics isn't instantly applauded.
What you are doing here is attempting to make Valtorta into something she is not, namely a formally approved visionary by the proper Church authorities in any way shape or form. I know, I know you'll say that the Vatican condemnation hardly holds weight against the supposed approval of Pius XII. I suppose it wouldn't, but what Pope would neglect to put in writing what he thought was important enough to approve? It doesn't matter really because hearsay has no weight. It might give you hope for some future recognition, but it doesn't give you the right to say it's good enough right now. It isn't, it really isn't.
Couple that with a desire to force all of us to agree with you lest we come across as "uncharitable" is a power play as much as any might pull around here. Precisely one of the reasons abortion is so abominable is because it robs those souls of the beatific vision. To all of the sudden reverse that church teaching because of one "mystic" is incredibly irresponsible. Not to mention, relying on an ill-advised conversation with a demoniac in the process!
You can do a lot better. If you're so concerned about unity among Catholics, then try to stay clear of the fringe topics. No one needs to believe Valtorta, a demon's ravings about anything, or the idea that all of the aborted go to Heaven. Is it really that difficult to stick to the tried and true? Do we have to constantly test each other's limits when we don't have to?
Prudence is a virtue!
