Of course you would accuse me of doubting Our Lady. Sedevacantists are mean and spiteful that way, and can't seem to keep from saying things like that.
Of course Our Lady didn't say anything about a "flat earth" to St. Catherine. We know that.
I didn't mean to be spiteful, however, why do you keep insisting or looking for other words that she must have said or meant instead of what she did say. It is very clear!
Anyway, it is you who has a mean outlook on anyone who claims to explain the Roman Catholic Church as being in the state of Sedevacantism. This topic has nothing to do with sedevacantism and yet you insist that Sedevacantist are mean and spiteful. You are mistaken, most don't even care what you or your ilk think about the shape of the earth.
For myself the answer is right there especially for Catholics no matter how you want to slice it, Blessed Mother talks about the earth being a globe-like shape. Forget the science! She should know for she has traveled from earth to heaven during her Assumption into heaven and her many apparitions back and forth, as the children have seen her coming and going, up into the heavens.
