I've looked into this apparition, and found it worthy of belief. Consonant with other approved Marian apparitions.
The only reason a bitter Trad would reject it -- Sister Sasagawa was in a Novus Ordo convent. Nevermind the fact the convent started receiving Communion on the tongue as a direct result of Sister Sasagawa and this apparition -- it bore GOOD FRUIT, as it were -- just saying -- but for some bitter Trads, anything less than fire and brimstone as punishment for attending the Novus Ordo is out of the question. No mercy, just hatred and justice.
For some bitter Trads, every single person who attends the Novus Ordo is malicious, of bad will, and in a state of Mortal sin.
In case you can't guess, I DO NOT consider myself among those bitter Trads.
Souls in the Novus Ordo, especially those of good will, have souls to save too. Jesus died for them as well, and He doesn't want to see them perish any more than the rest of humanity.
Some in the Novus Ordo have lost the Faith completely. They are there only for the heresy, and only *tolerate* the Catholic elements at best. Others are the complete reverse: they are there for the Catholic Faith, wanting to be part of the Church founded by Jesus Christ, and only *tolerate* the abuses, sentimentality, bad sermons, defects, etc. It would be completely foolishness to claim that these two groups are the same in God's eyes.
I think some Trads are so bitter and angry about being deceived (usually they spent time in the Novus Ordo themselves), that they hate the Novus Ordo and everyone in it.
Perhaps I should be grateful that I don't have such baggage -- and therefore I can take a more balanced, Catholic, and charitable position on the Novus Ordo/Conciliar Church.
