On December 8, the Church celebrates one of the most important feasts of Our Lady, the Feast of the Immaculate Conception of the Blessed Virgin Mary. This is the day when we remember and celebrate that God chose Mary to be the Mother of Jesus from the very first moment of her being; the moment of her conception.
History of Immaculate Conception
It is a day that celebrates the belief that Mary, mother of Jesus, was preserved from original sin all of her life.
For Roman Catholics, it is observed as a day of obligation with required church attendance.
The Immaculate Conception is a day whose meaning is often confused. By the sounds of it, one would think we would celebrate the day Jesus was conceived*. On the contrary, it is the day that the Blessed Mother Mary was conceived.
Mary's mother was St. Anne and her father was Joachim. While they are not mentioned in the bible, their names appear in some very early Christian texts. Anne and Joachim had been a childless couple until an angel appeared telling Anne that she would give birth to a child that the world would honour. Anne became a saint as she offered her child to god's service.
This day has been celebrated since at least the eighth century, but the idea that the word immaculate means that Mary was born without original sin divided many theological scholars over the centuries. It wasn't until 1854 that the argument was decided when Pope Pious IX proclaimed this belief to be an essential dogma of the Roman Catholic Church.
*If you think about it, December 8th is unlikely to be the date that Jesus was "conceived". It is the Feast of the Annunciation that celebrates the visit of the Archangel Gabriel to the Virgin Mary to announce to her that she would become the mother of Jesus. The date of the Feast of the Annunciation is March 25th - nine months before Christmas Day. Once the date of Christmas was finally accepted, then the March 25th was a no-brainer to be the date of the annunciation.
Special Non-Working Holiday
In accordance to Presidential Proclamation No. 845, December 8 or Feast of the Immaculate Conception of Mary is a special non-working Holiday in the Philippines.
On 29 December 2017 President Duterte signed Republic Act 10966, declaring 8 December of every year a special non-working holiday in the entire country "to commemorate the Feast of the Immaculate Conception of Mary, the principal patroness of the Philippines."
The Philippines has the third largest Catholic population in the world.
