How do YOU know?
God told you, did He?
You presume to know everything that God wills?
Your arrogance is astounding.
Anyway - I've already proven that "Kecharitomene" means "sinless".
NOBODY on earth is completely, perfectly and enduringly endowed with Grace - except for Mary. The rest of us have to wait until we get to Heaven to reach this status.
How do I know Mary was not required to be sinless? Because there is nothing in Scripture to say she was. You want to say she was. But your use of 'kecharitomene' to do it is laughable.
And if Mary was required to be sinless due to protecting the birth of Jesus Christ, then why isn't Mary's mother required to be sinless to protect Mary from being sinless? See how ridiculous you have made it.
