Feast of the Immaculate Conception of the Blessed Virgin Mary

This week, on Wednesday, December 8, we celebrate the Feast of the Immaculate Conception of the Blessed Virgin Mary. Not only is this a great feast of our Lady in its own right, but it is under the title of her Immaculate Conception that the United States is dedicated to our Lady as our patroness – it is our national feast day.

Here are 7 things you need to know about the teaching and the way we celebrate it.

1.  Who does the Immaculate Conception refer to?

There’s a popular idea that it refers to Jesus’ conception by the Virgin Mary. It doesn’t. Instead, it refers to the special way in which the Virgin Mary herself was conceived. This conception was not virginal.  (That is, she had a human father as well as a human mother.)  But it was special and unique in another way.

2.  What is the Immaculate Conception?

The dogma of the Immaculate Conception, proclaimed by Pope Pius IX in 1854 says:

The most Blessed Virgin Mary was, from the first moment of her conception, by a singular grace and privilege of almighty God and by virtue of the merits of Jesus Christ, Saviour of the human race, preserved immune from all stain of original sin. 

3.  Does this mean Mary never sinned?

Yes.  Because of the way redemption was applied to Mary at the moment of her conception, she not only was protected from contracting original sin but also personal sin.

4.  Does this mean Mary didn’t need Jesus to die on the Cross for her?

No. Mary was immaculately conceived by a singular grace of God and by virtue of the merits of Jesus Christ, dying on the Cross for us.

5.  How does this make Mary a parallel of Eve?

Adam and Eve were both created immaculate–without original sin or its stain. They fell from grace, and through them mankind was bound to sin.

Christ and Mary were also conceived immaculate. They remained faithful, and through them mankind was redeemed from sin.  Christ is thus the New Adam, and Mary the New Eve.

6.  Was it necessary for God to make Mary immaculate at her conception so that she could be Jesus’ mother?

No. The Church only speaks of the Immaculate Conception as something that was “fitting,” something that made Mary a “fit habitation” (i.e., suitable dwelling) for the Son of God, not something that was necessary.

7.  How do we celebrate the Immaculate Conception today?

In the Latin rite of the Catholic Church, December 8th is the

Solemnity of the Immaculate Conception. In the United States and in a number of other countries, it is a Holy Day of Obligation.
