“Ash Wednesday is for people who know that it means for their soul to be logged with these icy waters: all of us are such people, if only we can realize it.
There is confidence everywhere in Ash Wednesday, yet that does not mean unmixed and untroubled security. The confidence of the Christian is always a confidence in spite of darkness and risk, in the presence of peril, with every evidence of possible disaster…
Once again, Lent is not just a time for squaring conscious accounts: but for realizing what we had perhaps not seen before. The light of Lent is given us to help us with this realization.
Nevertheless, the liturgy of Ash Wednesday is not focussed on the sinfulness of the penitent but on the mercy of God. The question of sinfulness is raised precisely because this is a day of mercy, and the just do not need a savior.”
– Thomas Merton, quoted here.
