Pope Leo the Great: Lent is More Than Just a Diet

Pope Leo the Great on Lent:

Relying, therefore, dearly-beloved, on these arms, let us enter actively and fearlessly on the contest set before us: so that in this fasting struggle we may not rest satisfied with only this end, that we should think abstinence from food alone desirable. For it is not enough that the substance of our flesh should be reduced, if the strength of the soul be not also developed. When the outer man is somewhat subdued, let the inner man be somewhat refreshed; and when bodily excess is denied to our flesh, let our mind be invigorated by spiritual delights. Let every Christian scrutinise himself, and earth severely into his inmost heart: let him see that no discord cling there, no wrong desire be harboured. Let chasteness drive incontinence far away; let the light of truth dispel the shades of deception; let the swellings of pride subside; let wrath yield to reason; let the darts of ill-treatment be shattered, and the chidings of the tongue be bridled; let thoughts of revenge fall through, and injuries be given over to oblivion. In fine, let “every plant which the heavenly Father hath not planted be removed by the roots.” For then only are the seeds of virtue well nourished in us, when every foreign germ is uprooted from the field of wheat. If any one, therefore, has been fired by the desire for vengeance against another, so that he has given him up to prison or bound him with chains, let him make haste to forgive not only the innocent, but also one who seems worthy of punishment, that he may with confidence make use of the clause in the Lord’s prayer and say, “Forgive us our debts, as we also forgive our debtors.” Which petition the Lord marks with peculiar emphasis, as if the efficacy of the whole rested on this condition, by saying, “For if ye forgive men their sins, your Father which is in heaven also will forgive you: but if ye forgive not men, neither will your Father forgive you your Sins.”
