It is a dogma of the Church of Rome that the Virgin Mary was miraculously born without a taint of sin, that original sin, the sinful nature common to all of Adam's race, was entirely wanting in her by an act of Divine grace, that her humanity was as pure and sinless as that of her Divine Son.
For centuries this idea was debated but not till the 19th century was it officially promulgated. On 8th December, 1853, Pope Pius IX promulgated a bull, declaring this dogma to be an article of faith, and charging with heresy those who should doubt or speak against it. If it were true when the Virgin was born, why did it take over eighteen hundred years to find it out?
But one verse of Scripture settles the point, and that the inspired record of what the Virgin Mary herself said in the joy of her heart, when the news of the high honor of becoming the mother of our Lord according to the flesh was brought to her. She exclaimed in great exultation: "My spirit hath rejoiced in God MY Savior" (Luke 1:47).
Now if the Virgin, "blessed among women," had a Savior, she must have needed a Savior. And if she needed a Savior, she must have been a sinner, like every member of the fallen human race.
