Almost there! Really?
I Have observed many persons rejoicing, and saying one to another, "We have conquered; we have prevailed; the half of the fast is spent." But I exhort such persons not to rejoice on this account, that the half of the fast is gone, but to consider whether the half of their sins be gone; and if so, then to exult. For this is a fit subject of gratification. This is what is to be sought after, and for which all things are done, that we may correct our defects; and that we may not quit the fast the same persons as we entered upon it, but in a cleansed state; and that having laid aside all that belongs to evil habits, we may thus keep the sacred feast, since if the case be otherwise, we shall be so far from obtaining any advantage, that the completion of the fast will be the greatest injury to us.
What can be more feeble-minded than this? I ask; and what is the cause of this? It is, that when the fast is arrived, we do not take pains that the concerns of the soul may be well ordered, but we limit the fast solely to an abstinence from food.
from Homily XVIII.
