In today’s reading from the book of Deuteronomy, Moses, when speaking about the law, says,

“However, take care and be earnestly on your guard not to forget the things which your own eyes have seen, nor let them slip from your memory as long as you live, but teach them to your children and to your children’s children.”

Then in Matthew we have the words of Jesus,

“Do not think that I have come to abolish the law or the prophets.
I have come not to abolish but to fulfill.
Amen, I say to you, until heaven and earth pass away,
not the smallest letter or the smallest part of a letter
will pass from the law,
until all things have taken place.
Therefore, whoever breaks one of the least of these commandments
and teaches others to do so
will be called least in the Kingdom of heaven.
But whoever obeys and teaches these commandments
will be called greatest in the Kingdom of heaven.”

Here is a reflection on the law by Father Chidi Osondu from the Diocese of Savannah presented by the USCCB,
