Solemnity of Mary, mother of God.
This celebration is the octave of Christmas. An octave is an eight day extension of the feast. In the modern Roman Calendar, only Christmas and Easter have an octave. This holiday is a celebration of Mary’s motherhood of Jesus. It is a reminder of the role she played in the salvation of humankind. The title “Mother of God” is a western derivation from the Greek Theotokos, which means “God-bearer”.Mary being chosen by God, the Father, to bring Jesus Christ into this world, and her willingness to do so is great cause for celebration. Without her role, Jesus would not have been able to die for the sins of humans, thus giving them a second chance at redemption.
