Q: The anniversary of the dedication of our parish church is March 21, which falls on the Fifth Sunday of Lent this year. Which Mass do we celebrate?
==
A: Your Mass on March 21 will be the Fifth Sunday of Lent. That ranks at #2 on the Table of Liturgical Days, right below the Paschal Triduum.
The anniversary of the dedication of the church is #4b on the Table.
Because your church’s anniversary falls on a Sunday in Lent this year, the parish’s proper solemnity for the anniversary of the dedication of the church moves to March 22. It replaces the Lent weekday (#9 on the Table).
