The first Sunday in Lent being called Quadragesima, being the fortieth day before Easter; the three preceding Sundays were denominated, from the next round numbers, Quinquagesima, fiftieth; Sexagesima, sixtieth; and Quinquagesima, seventieth day before Easter.
The design of the Church in these Sundays is to call us from the feasting and joy of Christmas, to prepare for the fasting and humiliation proper for the approaching season of Lent; to bring us from thinking on the manner of CHRIST’S coming into the world, to reflecting on the cause of it, our own sins and miseries; that so, being convinced of the reasonableness of punishing and mortifying ourselves for our sins, we may the more strictly and religiously apply ourselves to the duties of humiliation, mortification, and repentance, during the season of Lent.
The Epistles for each of these three days are taken out of St. Paul’s Epistles to the Corinthians. The first two persuade us to acts of mortification and penance, by proposing to us St. Paul’s example. And because all acts of self-denial, unless founded upon charity, or in a principle of love to GOD and submission to his institutions, profit nothing; the Church, in the Epistle for Quinquagesima Sunday, sets before us this exalted virtue of Christian love and unity. The design of the Gospels is the same with that of the Epistles.
