Mary is a wonderful model of faith, not only during the Advent and Christmas Seasons, but always. 

As the Solemnity of the Immaculate Conception of the Blessed Virgin Mary is a holy day of obligation, Catholics will celebrate Mass on this day.  At Mass, listen carefully to the readings for today.  Reflect especially on how Mary’s “yes” at the Annunciation reversed the “no” or disobedience of Adam and Eve when they ate of the forbidden fruit in the Garden of Eden.
