DZ,
I don't get you.
I said it is the actual case that the BVM did not sin due to extraordinary graces received from God.
I'm not at odds with you man. She was just the biggest example to hand. Disregard that bit if it confuses.
Another rephrase, which would normally be bad because it is more technical and "Churchy"
By what causes may a man never sin?
Does this invariably apply to
each, every, and all men at all times in all circuмstances, no matter other causes? It seems to be assumed that some lone bushman of the atlantic out scratching himself, by himself, going nuts from cocoanuts, can "somehow" just avoid sinning. "Salvation in a bubble"
