SOLEMNITY OF THE IMMACULATE CONCEPTION OF THE BLESSED VIRGIN MARY
While this very important celebration is usually on December 8, since that is a Sunday this year, all the Masses for December 7/8 will be for the Second Sunday of Advent. The Solemnity of the Immaculate Conception is transferred to Monday, December 9. Although the Paulist Press Ordo says it is not a holy day of obligation this year, since the Diocese of Honolulu only celebrates two holy days of obligation throughout the year (Immaculate Conception and Christmas), the Solemnity of the Immaculate Conception WILL be celebrated on Monday, December 9, 2019, as a HOLY DAY OF OBLIGATION in the Diocese of Honolulu.
Pastors are asked to schedule Masses so that all may observe this holy day of obligation and to publicize that it is a holy day of obligation well in advance of December 9.
