Joshua 24:1-13 / Matthew 19:3-12
In education, “The three Rs” are three basic skills taught in schools: reading, writing and arithmetic (usually said as "reading, 'riting, and 'rithmetic").
With those three basic skills one would be able to get along.
And there are also another “Three Rs” in life.
They are Recall, Remember and Reflect.
These three Rs in life bring us back to our origins, and also to the basics of life.
In the 1st reading, that was what Joshua did for the people.
He recalled for them where they came from, he made them remember the wonders that God had done for them, and he also brought them to reflect on the promises that God had fulfilled for them.
In all this, Joshua hoped that the people will revere the Lord and be faithful to Him.
In the gospel, Jesus also made the Pharisees recall, remember and to reflect about what marriage was about.
Jesus brought them back to the beginning of creation, how God made male and female and the two became one.
And what God has united, no man must ever divide.
As for us, let us always recall, remember and reflect on who God is and what He has done for us.
As we recall, remember and reflect, let us revere the Lord and be faithful to Him.
God has called us to be His own; let us not separate ourselves from Him.
