Actually, Lent begins on Ash Wednesday (which was last Wednesday), but today is the First Sunday of Lent. And for the occassion, this is what we read this morning:
No Lent is worthy of the name without a personal effort of self-reformation, of leading a life more in accordance with God's commands and an attempt by some kind of voluntary self-denial to make reparation for past negligence. But the Church, together with the personal effort which she requires of all of us, her children, sets up in the sight of God the cross of Christ, the Lamb of God who took upon Himself the sins of man and who is the price of our redemption. As Holy Week approaches the thought of the passion becomes increasingly predominant until it occupies our whole attention, but from the very beginning of Lent it is present, for it is in union with the sufferings of Christ that the whole army of Christians begins on the holy "forty days", setting out for Easter with the glad certitude of sharing in His resurrection.
"Behold, now is the acceptable time, behold, now is the day of salvation." The Church puts Lent before us in the very same terms that formerly she put it before the catechumens and public penitents who were preparing for the Easter graces of baptism and sacramental reconciliation. For us, as it was for them, Lent should be a long retreat, one in which under the guidance of the Church we are led to the practice of a more perfect Christian life. She shows us the example of Christ and by fasting and penance associates us with his sufferings that we may have a share in His redemption.
We should remember that Lent is not an isolated personal affair of our own. The Church avails herself of the whole of the mystery of redemption. We belong to an immense concourse, a great body in which we are united to the whole of humanity which has been redeemed by Christ. The liturgy of this season does not fail to remind us of it.
This, then, is the meaning of Lent for us: a season of deepening spirituality in union with the whole Church which thus prepares to celebrate the Paschal mystery. Each year, following Christ its Head, the whole Christian people takes up with renewed effort its struggle against evil, against Satan and the sinful man that each one of us bears within himself, in order at Easter to draw new life from the very springs of divine life and to continue its progress towards heaven.
