Deuteronomy 4:1, 5-9 / Matthew 5:17-19
When we make an analysis of the content of what is being preached, then we will come to the conclusion that the same themes are being preached, day in day out, week in week out.
Themes like loving God and loving others, being faithful to God and to His Commandments, turning away from sin, etc.
If there is anything new, it is not so much in what is being preached but rather how it was preached.
If such is the case, then isn't it boring to hear the same things over and over again?
Well, it may be boring, but nonetheless, it is necessary.
Necessary because we have this tendency to forget. And hence we need to be reminded.
That is why in the 1st reading, Moses urged the people to keep the commandments and to observe them.
He warned them to be on their guard and not to forget the commandments nor let it slip from their hearts.
Furthermore, they should tell it to their children and to their children's children.
As it was then, so it is now. What Moses told the people, the Church is now telling us through her teachings and preaching.
And as Jesus said in the gospel, the man who keeps the commandments and teaches others to do the same will be considered great in the kingdom of heaven.
