Repost - not uncivil 

None. What proof do you have that it IS true? I can find absolutely NO reference to any such comment anywhere but her claim.
Sometimes stories are embellished to make a point supporting a particular agenda. Anecdotal stories get bigger and bigger...and Donna Quinn has quite an agenda to support. One sure way would be to diminish John Paul II.

Donna Quinn was (not sure if still) a Sinsinawa Dominican nun. She has certainly had run-ins with Cardinal George, then Pope John Paul II, and even her own rather liberal Congregation - which publicly chastised her on 11/2/2009 "After investigating the allegation, congregation leaders have informed Sister Donna that her actions are in violation of her profession as a Dominican religious...."

Not even sure she accepts Pope Francis - she has said his election was invalid.
Even CNN calls her "a radical leftist nun" -

I would like to see some validation that the claim is true....because I don't believe it is given her history
