Lenten Wisdom from the saints
Pope St Leo the Great (c. 400-461AD) Lenten sermon (Sermon 49)
“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. For who, that is set in the uncertainty of this life, can be found either exempt from temptation, or free from fault? Who is there who would not wish for additions to his virtue, or removal of his vice? Seeing that adversity does us harm, and prosperity spoils us, and it is equally dangerous not to have what we want at all, and to have it in the fullest measure. There is a trap in the fullness of riches, a trap in the straits of poverty. The one lifts us up in pride, the other incites us to complaint. Health tries us, sickness tries us, so long as the one fosters carelessness and the other sadness. There is a snare in security, a snare in fear; and it matters not whether the mind which is given over to earthly thoughts, is taken up with pleasures or with cares; for it is equally unhealthy to languish under empty delights, or to labour under racking anxiety.
And thus is perfectly fulfilled that assurance of the Truth, by which we learn that narrow and steep is the way that leads to life (Matt 7:14); and while the breadth of the way that leads to death is crowded with a large company, the steps are few of those that tread the path of safety. And wherefore is the left road more thronged than the right, save that the multitude is prone to worldly joys and carnal goods? And although that which it desires is short-lived and uncertain, yet men endure toil more willingly for the lust of pleasure than for love of virtue. Thus while those who crave things visible are unnumbered, those who prefer the eternal to the temporal are hardly to be found. And, therefore, seeing that the blessed Apostle Paul says, the things which are seen are temporal, but the things which are not seen are eternal (2Cor 4:18), the path of virtue lies hid and in concealment, to a certain extent, since by hope we were saved (Rom 8:24), and true faith loves that above all things, which it attains to without any intervention of the flesh. A great work and toil it is then to keep our wayward heart from all sin, and, with the numberless allurements of pleasure to ensnare it on all sides, not to let the vigour of the mind give way to any attack. Who touches pitch, and is not defiled thereby (Sirach 13:1)? who is not weakened by the flesh? Who is not begrimed by the dust? Who, lastly, is of such purity as not to be polluted by those things without which one cannot live? For the Divine teaching commands by the Apostle's mouth that they who have wives should be as though they had none: and those that weep as though they wept not; and those that rejoice as though they rejoiced not; and those that buy as though they possessed not; and those that use this world as though they used it not; for the fashion of this world passes away. Blessed, therefore, is the mind that passes the time of its pilgrimage in chaste sobriety, and loiters not in the things through which it has to walk, so that, as a stranger rather than the possessor of its earthly abode, it may not be wanting in human affections, and yet rest on the Divine promises.
Which of the faithful does not know what virtues he ought to cultivate, and what vices to fight against? Who is so partial or so unskilled a judge of his own conscience as not to know what ought to be removed, and what ought to be developed? Surely no one is so devoid of reason as not to understand the character of his mode of life, or not to know the secrets of his heart. Let him not then please himself in everything, nor judge himself according to the delights of the flesh, but place his every habit in the scale of the Divine commands, where, some things being ordered to be done and others forbidden, he can examine himself in a true balance by weighing the actions of his life according to this standard. For the designing mercy of God has set up the brightest mirror in His commandments, wherein a man may see his mind's face and realize its conformity or dissimilarity to God's image: with the specific purpose that, at least, during the days of our Redemption and Restoration, we may throw off awhile our carnal cares and restless occupations, and betake ourselves from earthly matters to heavenly.”
