Office Of Readings | Week 22, Thursday, Ordinary Time | The Beginning Of The Sermon Of Pope Saint Leo The Great On The Beatitudes | I Will Put My Law Within Them
‘I will put my law within them.’
Pope Saint Leo the Great situates the Sermon on the Mount within the wider pattern of salvation history. Christ’s ministry begins with acts of physical healing that attract crowds, but these serve as a preparation for his deeper teaching. The miracles are signs intended to draw attention to the doctrine that heals the soul. Thus, Leo highlights the shift from outward cures to inward remedies, presenting Christ as both healer of the body and physician of the heart.
The setting of the sermon is also given symbolic weight. By ascending a mountain, Christ evokes the figure of Moses who once received the law at Sinai. Yet Leo draws a deliberate contrast. Whereas the old covenant was given in thunder, lightning, and fear, the new covenant is communicated in tranquility and accessibility. This shift illustrates the transformation promised in Jeremiah 31:31–33: God’s law is no longer external but written within the heart, not on stone but in the inward being of believers.
Leo then turns to the Beatitudes as the clearest expression of this new law of grace. He begins with the first: ‘Blessed are the poor in spirit, for theirs is the kingdom of heaven.’ Poverty, understood in the sense of material deprivation alone, is not what Christ blesses. Instead, it is the poverty of spirit, which denotes humility and detachment, that marks those who belong to the kingdom. The teaching thus interiorises the law: rather than prescribing external obligations, it shapes inward dispositions.
Leo teaches continuity and transformation. The same God who spoke at Sinai now speaks through Christ, but the manner and purpose are renewed. Fear gives way to adoption, law to grace, outward observance to inward formation. In this way, the Sermon on the Mount embodies the fulfilment of prophecy and reveals the nature of the new covenant.
The Beginning Of The Sermon Of Pope Saint Leo The Great On The Beatitudes | I Will Put My Law Within Them
Dearly beloved, when our Lord Jesus Christ was preaching the Gospel of the kingdom and healing various illnesses throughout the whole of Galilee, the fame of his mighty works spread into all of Syria, and great crowds from all parts of Judaea flocked to the heavenly physician. Because human ignorance is slow to believe what it does not see, and equally slow to hope for what it does not know, those who were to be instructed in the divine teaching had first to be aroused by bodily benefits and visible miracles so that, once they had experienced his gracious power, they would no longer doubt the wholesome effect of his doctrine. In order, therefore, to transform outward healings into inward remedies, and to cure men’s souls now that he had healed their bodies, our Lord separated himself from the surrounding crowds, climbed to the solitude of a neighbouring mountain, and called the apostles to himself. From the height of this mystical site he then instructed them in the most lofty doctrines, suggesting both by the very nature of the place and by what he was doing that it was he who long ago had honoured Moses by speaking to him. At that time, his words showed a terrifying justice, but now they reveal a sacred compassion, in order to fulfil what was promised in the words of the prophet Jeremiah: Behold the days are coming, says the Lord, when I shall establish a new covenant with the house of Israel and with the house of Judah. After those days, says the Lord, I shall put my laws within them and write them on their hearts.
And so it was that he who had spoken to Moses spoke also to the apostles. Writing in the hearts of his disciples, the swift hand of the Word composed the ordinances of the new covenant. And this was not done as formerly, in the midst of dense clouds, amid terrifying sounds and lightning, so that the people were frightened away from approaching the mountain. Instead, there was a tranquil discourse which clearly reached the ears of all who stood nearby so that the harshness of the law might be softened by the gentleness of grace, and the spirit of adoption might dispel the terror of slavery.
Concerning the content of Christ’s teaching, his own sacred words bear witness; thus whoever longs to attain eternal blessedness can now recognise the steps that lead to that high happiness. Blessed, he says, are the poor in spirit, for theirs is the kingdom of heaven. It might have been unclear to which poor he was referring, if after the words Blessed are the poor, he had not added anything about the kind of poor he had in mind. For then the poverty that many suffer because of grave and harsh necessity might seem sufficient to merit the kingdom of heaven.
But when he says: Blessed are the poor in spirit, he shows that the kingdom of heaven is to be given to those who are distinguished by their humility of soul rather than by their lack of worldly goods.
Christian Prayer With Jesus Christ
Lord Jesus Christ, teacher and healer,
you revealed the new law of grace from the mountain,
writing it not on stone but within our hearts.
Grant us poverty of spirit,
that we may be freed from pride and possess your kingdom.
May your word shape our thoughts and actions,
so that, living as children of adoption,
we walk the path of the Beatitudes
and find our joy in you,
who live and reign with the Father and the Holy Spirit,
one God, for ever and ever. Amen.

Christian Art | George Herbert | The Temple | The Church | The Sinner George Herbert | The Temple | The Church | The Sinner Lord, how I am all ague, when I seek What I have treasur’d in my memorie! Since, if my soul make even with the week, Each seventh note by right is due to thee. I finde there quarries of pil’d vanities, But shreds of holinesse, that dare not venture To shew their face, since crosse to thy decrees. There the circumference earth is, heav’n the centre. In so much dregs the quintessence is small: The spirit and good extract of my heart Comes to about the many hundredth part. Yet Lord restore thine image, heare my call: And though my hard heart scarce to thee can grone, Remember that thou once didst write in stone. George Herbert | The Temple | The Church | The Sinner The poet reflects on his spiritual state, describing a struggle with weakness, sin, and the desire for divine alignment. The poem opens with the poet addressing God, expressing discomfort, likened to an ‘ague’ (fever or chill), when he searches his memory for spiritual treasures. This ‘ague’ suggests both a physical and spiritual unease, revealing the tension the poet feels in self-examination. The second line conveys a sense of regret as the poet searches for ‘treasur’d’ holiness in his memory. He recognizes that, although he might strive to keep his soul ‘even with the week’, dedicating every seventh day to God, he falls short. This phrase reflects the expectation to honour the Sabbath, but the poet’s efforts are met with disappointment in their perceived spiritual emptiness. The poet goes on to examine his inner self, describing ‘quarries of pil’d vanities’ that dominate his mind. Here, ‘quarries’ implies an overwhelming quantity of earthly or superficial concerns, while ‘vanities’ suggests that these concerns are meaningless in the context of divine expectation. In contrast, he finds only ‘shreds of holinesse’, fragmented attempts at righteousness, which he hesitates to bring forward as these elements are ‘crosse to thy decrees’, or in opposition to God’s laws. This imagery underscores the poet’s internal conflict and recognition of shortcomings. Further, the poet contrasts earth and heaven, saying that ‘the circumference earth is, heav’n the centre.’ This phrase symbolizes the poet’s focus on worldly concerns (the circumference) that orbit around a neglected spiritual core (the heavenly center). The poet reflects that his life is filled with ‘dregs’, the lesser, unrefined aspects of his being, while ‘quintessence’, or the purest part of himself, is scarce. This ‘quintessence’ is described as the ‘spirit and good extract’ of the poet’s heart, amounting to a ‘many hundredth part’ — a small fraction of life’s essence. The poet realizes that, despite attempts to cultivate holiness, his internal state largely lacks spiritual substance. The final lines shift to a plea for restoration. The poet calls on God to ‘restore thine image’, asking for renewal and transformation. This restoration request implies a yearning to reflect God’s nature more fully, as humanity is believed to be made in God’s image. The poet acknowledges that his heart ‘scarce… can grone’ to God, reflecting the difficulty he feels in truly connecting with or petitioning the divine. The poem ends with reference to the biblical account of the Ten Commandments, when God ‘didst write in stone’. This allusion serves as both a reminder of God’s past willingness to communicate directly and a plea for a similar intervention to etch divine law into the poet’s heart. The poem examines themes of introspection, human fallibility, and a longing for divine transformation. The poet’s self-examination reveals struggle to balance earthly concerns with spiritual commitments, culminating in a plea for God’s direct action to restore spiritual integrity.
Jesus does not change his message in order to please people, even when that message proves unpalatable. He has not come to be all things to all men, but instead to tell us the truth. It is up to us, through faith, to hear and to understand and to accept Jesus’ teachings, and to know that our salvation is through him [ … ]
