According to this dogmatic definition, it has been revealed by God that Mary was preserved from original sin from the moment of her conception
At the General Audience of Wednesday, 12 June, 1854, the Holy Father continued his catechesis on the Immaculate Conception, this time discussing the dogmatic definition of the doctrine by Pope Pius IX. “We declare, pronounce and define that the doctrine which asserts that the Blessed Virgin Mary, from the first moment of her conception, by a singular grace and privilege of almighty God, and in view of the merits of Jesus Christ, Saviour of the human race, was preserved free from every stain of original sin is a doctrine revealed by God and, for this reason, must be firmly and constantly believed by all the faithful”, the Pope said in his Bull Ineffabilis. Here is a translation of the Holy Father’s catechesis, which was the 23rd in the series on the Blessed Virgin and was given in Italian.
- Down the centuries, the conviction that Mary was preserved from every stain of sin from her conception, so that she is to be called all holy, gradually gained ground in the liturgy and theology. At the start of the 19th century, this development led to a petition drive for a dogmatic definition of the privilege of the Immaculate Conception.
Around the middle of the century, with the intention of accepting this request, Pope Pius IX, after consulting the theologians, questioned the Bishops about the opportuneness and the possibility of such a definition, convoking as it were a “council in writing”. The result was significant: the vast majority of the 604 Bishops gave a positive response to the question.
After such an extensive consultation, which emphasized my venerable Predecessor’s concern to express the Church’s faith in the definition of the dogma, he set about preparing the document with equal care.
Blessed Virgin is free from every stain of sin
The special commission of theologians set up by Pius IX to determine the revealed doctrine assigned the essential role to ecclesial practice. And this criterion influenced the formulation of the dogma, which preferred expressions taken from the Church’s lived experience, from the faith and worship of the Christian people, to scholastic definitions.
Finally in 1854, with the Bull Ineffabilis, Pius IX solemnly proclaimed the dogma of the Immaculate Conception: “… We declare, pronounce and define that the doctrine which asserts that the Blessed Virgin Mary, from the first moment of her conception, by a singular grace and privilege of almighty God, and in view of the merits of Jesus Christ, Saviour of the human race, was preserved free from every stain of original sin is a doctrine revealed by God and, for this reason, must be firmly and constantly believed by all the faithful” (DS 2803).
