Mary wasn't conceived immaculately.
That is an unscriptural fantasy.
Furthermore,
the Romish doctrine of the "immaculate conception",
pertaining to how Mary herself was conceived,
does not describe,
and is not meant to be referring to,
how Christ Jesus was conceived in Mary's womb.
The reference to Mary's conception in her mother's womb,
is that the sin nature from her father's seed was not applied to her.
Christ Jesus was not conceived with an earthly father's seed.
He was conceived ONLY with Mary's own seed,
her egg.
There is therefore no need for Mary having any special category relative to her own nature,
since the sin nature,
by legal curse,
can only pass from father to children,
having passed down from Adam.
Mary, therefore,
was also born in sin,
having inherited that nature from her father,
but being a woman,
could not legally pass any inheritance,
keeping Christ Jesus sanctified.
The doctrine of the "immaculate conception" is not only false,
but it is totally unnecessary,
born out of ignorance and conveniently used by the Dragon to deceive.
