A Blessed Feast of the Immaculate Conception to All!

Beginning this evening and throughout all of tomorrow, the Catholic Church celebrates the Feast of the Immaculate Conception of the Blessed Virgin Mary. This teaching is one of the four Marian Dogmas, to be held by all of the faithful. Formally defined by Pope Piux IX in the Apostolic Constitution Ineffabilis Deus,the dogma is formulated as follows:

"... the most Blessed Virgin Mary, in the first instance of her conception, by a singular grace and privilege granted by Almighty God, in view of the merits of Jesus Christ, the Savior of the human race, was preserved free from all stain of original sin..."

So great would be the Child of the Blessed Virgin Mary, that she had to be absolutely pure and spotless. So perfect was our Lord Jesus' love for His mother that He saved her in anticipation. What a glorious gift He had given to His mother! And what a glorious gift He has given us by putting us under her care! On this day, brothers and sisters, let us praise and thank God for giving us the Blessed Virgin Mary, this most holy and powerful intercessor!

From Vespers I:
O God, Who by the Immaculate Conception of the Blessed Virgin prepared a worthy dwelling for your Son, grant, we pray, that, as You preserved her from every stain by virtue of the Death of Your Son, which You foresaw, so through her intercession, we, too, may be cleansed and admitted to Your Presence. Through our Lord Jesus Christ, Your Son, Who lives and reigns with You in the unity of the Holy Spirit, one God, for ever and ever. Amen
