Bernadette had 18 apparitions of the "Mother of God" which started on February 11, 1858
The Mother of God confirmed the dogma (church doctrine which is not to be disputed or doubted) of the Immaculate Conception
The Immaculate Conception is church doctrine that the Virgin Mary was born without Original Sin
Four humans were born without Original Sin: Jesus, the Virgin Mary, Adam, and Eve
Four years earlier, Pope Pius IX had raised the Immaculate Conception to the dignity of a dogma of the infallible Church
The Mother of God also promised Bernadette that she would not be happy in this world, but in the next
St. Bernadette's body was exhumed after 30 years and was found incorrupt
Saint Anthony Chapel has a second-class relic of the habit of St. Bernadette
