EWTN Catholic Q&A
Question from J.F. on 09-08-2013:

We used to celebrate the Nativity or birth of Mary on September 8 every year, as well as Our Lady of Sorrows on September 15. I have not see this feast on the Catholic calendar and, more disappointingly, I heard nothing at Mass when it fell on a Sunday this year, 2013.

Answer by Catholic Answers on 09-09-2013:


That's because it did fall on a Sunday. Sunday takes precedence over feast days. Only a solemnity, not a feast or a memorial, takes precedence over the regular Sunday liturgy. Both the Nativity of the Blessed Virgin (September 8) and Our Lady of Sorrows (September 15) are superseded by Sunday this year.
