The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2018-10-07:
Luke 1:46-55
46And Mary said, "My soul magnifies the Lord, 47and my spirit rejoices in God my Savior, 48for he has regarded the low estate of his handmaiden. For behold, henceforth all generations will call me blessed;49for he who is mighty has done great things for me, and holy is his name. 50And his mercy is on those who fear him from generation to generation. 51He has shown strength with his arm, he has scattered the proud in the imagination of their hearts, 52he has put down the mighty from their thrones, and exalted those of low degree;53he has filled the hungry with good things, and the rich he has sent empty away. 54He has helped his servant Israel, in remembrance of his mercy, 55as he spoke to our fathers, to Abraham and to his posterity for ever."
Luke 1:26-38
26In the sixth month the angel Gabriel was sent from God to a city of Galilee named Nazareth, 27to a virgin betrothed to a man whose name was Joseph, of the house of David;and the virgin's name was Mary. 28And he came to her and said, "Hail, full of grace, the Lord is with you!"29But she was greatly troubled at the saying, and considered in her mind what sort of greeting this might be. 30And the angel said to her, "Do not be afraid, Mary, for you have found favor with God. 31And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. 32He will be great, and will be called the Son of the Most High;and the Lord God will give to him the throne of his father David, 33and he will reign over the house of Jacob for ever;and of his kingdom there will be no end." 34And Mary said to the angel, "How shall this be, since I have no husband?" 35And the angel said to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you;therefore the child to be born will be called holy, the Son of God. 36And behold, your kinswoman Elizabeth in her old age has also conceived a son;and this is the sixth month with her who was called barren. 37For with God nothing will be impossible." 38And Mary said, "Behold, I am the handmaid of the Lord;let it be to me according to your word." And the angel departed from her.
Gn 2:18-24
The LORD God said: "It is not good for the man to be alone.
I will make a suitable partner for him."
So the LORD God formed out of the ground
various wild animals and various birds of the air,
and he brought them to the man to see what he would call them;
whatever the man called each of them would be its name.
The man gave names to all the cattle,
all the birds of the air, and all wild animals;
but none proved to be the suitable partner for the man.
So the LORD God cast a deep sleep on the man,
and while he was asleep,
he took out one of his ribs and closed up its place with flesh.
The LORD God then built up into a woman the rib
that he had taken from the man.
When he brought her to the man, the man said:
"This one, at last, is bone of my bones
and flesh of my flesh;
this one shall be called 'woman, '
for out of 'her man' this one has been taken."
That is why a man leaves his father and mother
and clings to his wife,
and the two of them become one flesh.
Ps 128:1-2, 3, 4-5, 6
R. (cf. 5)
May the Lord bless us all the days of our lives.
Blessed are you who fear the LORD,
who walk in his ways!
For you shall eat the fruit of your handiwork;
blessed shall you be, and favored.
R.May the Lord bless us all the days of our lives.
Your wife shall be like a fruitful vine
in the recesses of your home;
your children like olive plants
around your table.
R.May the Lord bless us all the days of our lives.
Behold, thus is the man 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.May the Lord bless us all the days of our lives.
May you see your children's children.
Peace be upon Israel!
R.May the Lord bless us all the days of our lives.
Heb 2:9-11
Brothers and sisters:
He "for a little while" was made "lower than the angels, "
that by the grace of God he might taste death for everyone.
For it was fitting that he,
for whom and through whom all things exist,
in bringing many children to glory,
should make the leader to their salvation perfect through suffering.
He who consecrates and those who are being consecrated
all have one origin.
Therefore, he is not ashamed to call them 'brothers.'
Mk 10:2-16
The Pharisees approached Jesus and asked,
"Is it lawful for a husband to divorce his wife?"
They were testing him.
He said to them in reply, "What did Moses command you?"
They replied,
"Moses permitted a husband to write a bill of divorce
and dismiss her."
But Jesus told them,
"Because of the hardness of your hearts
he wrote you this commandment.
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,
no human being must separate."
In the house the disciples again questioned Jesus about this.
He 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."
And people were bringing children to him that he might touch them,
but the disciples rebuked them.
When Jesus saw this he became indignant and said to them,
"Let the children come to me;
do not prevent them, for the kingdom of God belongs to
such as these.
Amen, I say to you,
whoever does not accept the kingdom of God like a child
will not enter it."
Then he embraced them and blessed them,
placing his hands on them.
