One thing I point out to those Orthodox Christians who do have a problem with the title (Immaculate Conception) is the focus of the liturgical texts for today (December 8, the feast of the Immaculate Conception of Mary)…the texts focus on Mary’s purity and sinlessness, from the first moment of her conception, as a perfect model and type of the Church. All these scholastic arguments about original sin are quite peripheral to the Church’s actual celebration of this mystery. The average Catholic today, who loves our Blessed Mother, is simply praising her purity and striving to be pure him/herself.
Collect for today’s mass:
O God, who by the Immaculate Conception of the Blessed Virgin Mary 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, forever and ever. Amen.
