In general, it can be said that no contemplative life is possible without ascetic self-discipline. One must learn to survive without the habit-forming luxuries which get such a hold on men today. I do not say that to be a contemplative one absolutely has to go without smoking or without alcohol, but certainly one must be able to use these things without being dominated by an uncontrolled need for them.
Thomas MertonNevertheless, 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.
