What an asinine argument.
I never claimed that Moses or the others were sinless - only Mary.
She is the ONLY one in Scripture to be described as "Kecharitomene."
Pay attention. You were using Abraham, Moses, and Isaiah, as examples of salvation like unto Mary's. Which is a false comparison because you are saying Mary was sinless. Which is a lie. But you acknowledge that Abaraham, Moses, and Isaiah were sinners...I assume. Who knows what you may believe.
