Today is Saturday before Septuagesima, and Roseanne Sullivan has an article on Dappled Things about the custom of bidding farewell to the Alleluia on this day:
In 1969, the Septuagesima season was removed from the liturgical calendar and its three Sundays and two week days were absorbed into Ordinary time. Even though I was raised a Catholic and attended Mass for years before the liturgical calendar was changed, I only heard about Septuagesima maybe six years ago, and I’m still finding out what it means. For me, as I’m sure is true for others, writing about a subject is the best way to learn about it. It’s a rich topic, and I can just barely scratch the surface, but here goes with a little introduction to Septuagesima, for those who live in an ordinary time world or those who, like me, worship according to the traditional calendar, but just haven’t been paying attention.
