On all days and seasons, indeed, dearly-beloved, some marks of the Divine goodness are set, and no part of the year is destitute of sacred mysteries, in order that, so long as proofs of our salvation meet us on all sides, we may the more eagerly accept the never-ceasing calls of God's mercy. But all that is bestowed on the restoration of human souls in the various works and gifts of grace is put before us more clearly and abundantly now, when no isolated portions of the Faith are to be celebrated, but the whole together. For as the Easter festival approaches, the greatest and most binding of fasts is kept, and its observance is imposed on all the faithful without exception; because no one is so holy that he ought not to be holier, nor so devout that he might not be devouter.
Leo the Great, Sermon XI on Lent
