According to The Bible two things are clear. One is that all humans are sinners. Secondly, the Bible does not indicate anything to contradict this for any individual, no matter how holy or blessed, and Mary is indeed blessed for being the mother of Jesus.
Thus the doctrines of the immaculate conception, perpetual virginity and anything else which contradicts the clear word of God does not have scriptural authority.
Roman Catholic AnswerThrough the merits of her son, Jesus Christ, and His passion, Mary was conceived without the stain of original sin. When Adam and Eve were created by God, they were created without sin, they fell, and in doing so lost original justice. As our first parents they did not have it to pass on. It's like they lost the gene and so all of the rest of us did not receive it, as they no longer had it to pass on. When Mary was conceived, God granted her the effects of that salvation that would come from Jesus' passion, from the first moment of her conception, and did not allow the shadow of that first fault to affect her. This we call the Immaculate Conception and it was done so that no sin or its effects would touch the body of Our Blessed Savior.Carmelites of Mary Immaculate was created in 1831.
