Immaculate Conception, of the Blessed Virgin Mary

The Immaculate Conception of the Blessed Virgin Mary is a foundational dogma of the Catholic Church, affirming that Mary was preserved free from original sin from the first moment of her existence. This unique privilege was granted in preparation for her role as the mother of Jesus Christ, the Savior. Venerated by Catholics worldwide, her sinless conception underscores her special place in salvation history. The doctrine was solemnly defined by Pope Pius IX in 1854.
