Pope Sixtus IV establishe
Pope Sixtus IV established this concept's feast and this concept was established as dogma by Pius IX. In Ineffabilis Deus, Pius IX claimed scriptural evidence for this concept in the Book of Luke 1:28, where Gabriel offers a greeting, and in Genesis 3:15, in a warning made by God towards the serpent. Protestants reject this doctrine, since Jesus is the only figure stated in the Bible to have no sin but Catholics accept it for that very reason. Arguing that Mary was in complete faith throughout her entire life, for 10 points, name this doctrine which states that the Virgin was protected by God from Original Sin at the birth of Christ.
