"The Season of Septuagesima comprises the three weeks immediately preceding Lent. It forms one of the principal divisions of the Liturgical Year, and is itself divided into three parts, each part corresponding to a week: the first is called Septuagesima; the second, Sexagesima; the third, Quinquagesima.
All three are named from their numerical reference to Lent, which, in the language of the Church, is called Quadragesima, — that is, Forty, — because the great Feast of Easter is prepared for by the holy exercises of Forty Days. The words Quinquagesima, Sexagesima, and Septuagesima, tell us of the same great Solemnity as looming in the distance, and as being the great object towards which the Church would have us now begin to turn all our thoughts, and desires, and devotion.
Now, the Feast of Easter must be prepared for by a forty-days’ recollectedness and penance. Those forty-days are one of the principal Seasons of the Liturgical Year, and one of the most powerful means employed by the Church for exciting in the hearts of her children the spirit of their Christian Vocation. It is of the utmost importance, that such a Season of grace should produce its work in our souls, — the renovation of the whole spiritual life. The Church, therefore, has instituted a preparation for the holy time of Lent. She gives us the three weeks of Septuagesima, during which she withdraws us, as much as may be, from the noisy distractions of the world, in order that our hearts may be the more readily impressed by the solemn warning she is to give us, at the commencement of Lent, by marking our foreheads with ashes.
The grave maternal voice of the Church will soon be heard, inviting us to the Lenten penance; but she wishes us to prepare for this laborious baptism, by employing these three weeks in considering the deep wounds caused in our souls by sin.
Our Jesus is the Victim of the divine justice, and he has now attained the fulness of his age; the altar, on which he is to be slain, is ready: and since it is for us that he is to be sacrificed, we should at once set ourselves to consider, what are the debts we have contracted towards that infinite Justice, which is about to punish the Innocent One instead of us the guilty."
- Dom Prosper Gueranger on Septuagesima
