History and Significance of Dogma of Immaculate Conception

The dogma of the Immaculate Conception, proclaimed 150 years ago, rediscovers in its profundity the expression "full of grace," says a consultor of the Congregation for the Doctrine of the Faith.

Discalced Carmelite Father Jesus Castellano Cervera, a specialist in Marian studies, reflects in this interview with ZENIT on the origin and significance of this dogma. Next month John Paul II will make a pilgrimage to Lourdes, the place in France where the Blessed Virgin appeared in 1858 and confirmed the truth of her immaculate conception.
