This year Christmas falls on a Monday. This means that the Vigil Mass and the Night Mass will take place on Sunday, 24 December. These Masses do not fulfil the obligation of attending a Mass for the 4th Sunday of Advent. Likewise, the 4th Sunday of Advent Masses do not fulfil the obligation of attending a Christmas Mass. Basically you need to come to two Masses that weekend. Here is breakdown of the various Masses and what qualifies for each Obligaton.
Advent & Christmas Season
The season of Advent starts Sunday, 3 December. We will bless the Advent candles at during this weekend. The Gloria will not be used at the Mass, and the bells at the start of Mass will be silenced. The seasonal colour is violet, except for the third Sunday - Gaudate Sunday or Rejoicful Sunday - when the colour will be rose. We have many special things planned for the season of Advent and Christmas.
