Quinquagesima Sunday is the last of the three Sundays of the short transitional season of Septuagesima. Ash Wednesday is this week and so begins the penitential season of Lent.
During Lent, we will sing the commons of Mass XVII (seventeen), which is for Advent and Lent. Recall our rule of thumb: If the priest is wearing green, we usually sing Mass XI (eleven), and if the priest is wearing violet, we usually sing Mass XVII. Of course, Septuagesima is the exception to this general rule because the priest is wearing violet but the Liber Usualis prescribes Mass XI (generally, without the Gloria).
The use of the organ is suppressed during Lent, so this Sunday is also noteworthy because it is the last time we will hear the organ (apart from a few exceptions that we will cover when the time comes).
On the first Sunday of every month, the men of our Holy Name Society pay special honor to the Holy Names of God and Jesus by entering the church in procession with the priest and servers, sitting together in the front of the church, and by receiving communion together as a body. To further honor the Holy Names, we will sing Jesu Dulcis Memoria, the 12th century vespers hymn for the Feast of the Holy Name.Each month of the calendar year has its dedication, and this month is the month of St. Joseph, whose feast day falls on the 19th. We will honor St. Joseph today with two hymns.
