6th Sunday in Ordinary Time — Gospel: Matthew 5:17-37
In his Sermon on the Mount, Jesus fulfills the Law by intensifying its moral standards.
He “insists on conversion of heart” (Catechism paragraph 2608), showing us that we are accountable not only for our actions, but for our thoughts and words as well. In this way Jesus raises the bar, so to speak, on the sin of anger (2262), on purity of thought (2336), sanctity of marriage (2382), reverence for God’s name (2153), and being truthful (2466).
“The Lord’s Sermon on the Mount, far from abolishing or devaluing the moral prescriptions of the Old Law, releases their hidden potential and has new demands arise from them: it reveals their entire divine and human truth. It does not add new external precepts, but proceeds to reform the heart, the root of human acts, where man chooses between the pure and the impure” (1968).
Hence the New Law, the Law of the Gospel, “becomes the interior law of charity” (1965), teaching us what we ought to do (1966).
As St. Augustine wrote, the Sermon on the Mount is “the perfect way of the Christian life,” containing “all the precepts needed to shape one’s life” (quoted in 1966).
For this reason, the Sermon on the Mount is one guide to an examination of conscience, especially to prepare for the sacrament of Reconciliation (1454).
Question for reflection: How carefully do I guard my thoughts and my words?
