"With the completion of the year's cycle, the season of Lent has come, at which time I am constrained to exhort you because you owe the Lord works in harmony with the spirit of the season, works which, nevertheless, are useful not to the Lord, but to you. True, other seasons of the year ought to glow for the Christian by reason of his prayers, fasts, and almsdeeds, but this season ought to arouse even those who are sluggish at other times. In fact, those who are quick to attend to these works at other times should now perform them with even greater diligence. Life in this world is certainly the time of our humiliation as these days signify when the sufferings of the Lord Christ, who once suffered by dying for us, are renewed each year with the recurrence of this holy season."
"For what was done once and for all time so that our life might be renewed, is solemnized each year so that its memory may be kept fresh. If, therefore, we ought to be humble of heart with sentiments of most sincere piety throughout the entire period of our earthly sojourn when we live in the midst of temptations, how much more necessary is humility during these days when we not only pass the time of our humiliation by living but signalize it by special devotion? The humility of Christ has taught us to be humble because He yielded to the wicked by His death; the exaltation of Christ lifts us up because by rising again He blazed the way for His devoted followers. For, 'if we have died with him, we shall also live with him; if we endure, we shall also reign with him' (2 Tim 2:11-13). One of these conditions we now celebrate with due observance in view of His approaching Passion; the other we shall celebrate after Easter when His Resurrection is, as it were, accomplished again. Then, after the days of this humiliation will be the time of our exaltation. Although this is not yet the time to experience this [happiness], it gives us pleasure to anticipate it in our considerations. Now, therefore, let us voice our lamentations more insistently in prayers; then we shall exult more exuberantly in praise."
