Please do not engage in false accusations and misrepresentations.

Not one non-Catholic has ever denied the virgin birth. There's a world of difference between the virgin birth and the alleged perpetual virginity of Mary.

If Mary, the Blessed Mother, was such a sinner, how could Jesus Christ been the "Perfect Sacrifice"?

Because the sin nature comes through the father, not the mother.

Besides, if Jesus could not have been born sinless because Mary was a sinner, then how could Mary be born sinless if HER parents were sinners?

Seems as if you, AL, are trying to interpret FR Threads like the RCC interprets Scripture. You read BETWEEN the lines of a post, something that CLEARLY does not exist, and base your claims and accusations on the text that ISN’T EVEN THERE. Sorta like “Mary was without original sin, Mary was bodily resurrected at her death, Mary is the queen of Heaven, etc.”.
If you spent more time ACTUALLY reading what is ACTUALLY written, you might find a little peace. And security.

Simple. It's called the Immaculate Conception.
