Last year we examined the Collects for Mass during Lent. This year let’s look at the Super Oblata. There is a page for Lenten prayers. Also, you can right click the calendar image to "View" and see a larger version.
Sacrificium quadragesimalis initii sollemniter immolamus,
te, Domine, deprecantes,
ut per paenitentiae caritatis labores
a noxiis voluptatibus temperemus,
et, a peccatis mundati,
ad celebrandam Filii tui passionem
mereamur esse devoti.
This prayer has roots in the ancient Gelasian and the Gregorian Sacramentary.
REALLY LITERAL VERSION:
Praying to You, O Lord,
we solemnly raise up the Sacrifice of the beginning of Lent,
so that through the exertions of the charity of penitence
we may abstain from harmful pleasures,
and, cleansed from sins,
we may be worthy to be dedicated
to celebrating the Passion of Your Son.
Some of the Fathers would to the time of the Lenten fast as a sacramentum, preparing us for the mysterium of the dying and rising of the Lord. For example, St. Leo the Great in his magnificent Lenten sermons refers often to the season as sacramentum.
Here at the threshold of Lent, let us make our "Lenten start". In the sacrament of Penance, Christ will cleanse your slate and you may make a renewed beginning.
