First Reading Genesis 2.7ab, 15, 18-24
The Lord God formed man from the dust of the ground, and breathed into his nostrils the breath of life, and put him in the garden of Eden to till it and keep it.
Then the Lord God said, “It is not good that the man should be alone; I will make him a helper as his partner.” So out of the ground the Lord God formed every animal of the field and every bird of the air, and brought them to the man to see what he would call them; and whatever the man called every living creature, that was its name. The man gave names to all cattle, and to the birds of the air, and to every animal of the field; but for the man there was not found a helper as his partner.
So the Lord God caused a deep sleep to fall upon the man, and he slept; then he took one of his ribs and closed up its place with flesh. And the rib that the Lord God had taken from the man he made into a woman and brought her to the man.
Then the man said, “This at last is bone of my bones and flesh of my flesh; this one shall be called Woman, for out of Man this one was taken.”
Therefore a man leaves his father and his mother and clings to his wife, and they become one flesh.
Psalm 128
R. May the Lord bless us all the days of our lives.
Blessed is everyone who fears the Lord, who walks in his ways. You shall eat the fruit of the labour of your hands; you shall be happy, and it shall go well with you. R.
Your wife will be like a fruitful vine within your house; your children will be like olive shoots around your table. R.
Thus shall the man be blessed who fears the Lord. The Lord bless you from Zion. May you see the prosperity of Jerusalem all the days of your life. R.
Second Reading Hebrews 2.9-11
We do indeed see Jesus, who for a little while was made lower than the Angels, now crowned with glory and honour because of the suffering of death, so that by the grace of God he might taste death for everyone.
It was fitting that God, for whom and through whom all things exist, in bringing many sons and daughters to glory should make the pioneer of their salvation perfect through sufferings. For the one who sanctifies and those who are sanctified are all from one. For this reason he is not ashamed to call them brothers and sisters.
Gospel Mark 10.2-12
Some Pharisees came, and to test Jesus they asked, “Is it lawful for a man to divorce his wife?” Jesus answered them, “What did Moses command you?” They said, “Moses allowed a man to write a certificate of dismissal and to divorce her.”
But Jesus said to them, “Because of your hardness of heart he wrote this commandment for you. But from the beginning of creation, ‘God made them male and female.’ ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.’ So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.”
Then in the house the disciples asked him again about this matter. Jesus said to them, “Whoever divorces his wife and marries another commits adultery against her; and if she divorces her husband and marries another, she commits adultery.”
