First Reading Genesis 18.1-10a
The Lord appeared to Abraham by the oaks of Mamre, as Abraham sat at the entrance of his tent in the heat of the day. Abraham looked up and saw three men standing near him. When he saw them, he ran from the tent entrance to meet them, and bowed down to the ground.
He said, “My lord, if I find favour with you, do not pass by your servant. Let a little water be brought, and wash your feet, and rest yourselves under the tree. Let me bring a little bread, that you may refresh yourselves, and after that you may pass on — since you have come to your servant.” So they said, “Do as you have said.”
And Abraham hastened into the tent to Sarah, and said, “Make ready quickly three measures of choice flour, knead it, and make cakes.” Abraham ran to the herd, and took a calf, tender and good, and gave it to the servant, who hastened to prepare it. Then he took curds and milk and the calf that he had prepared, and set it before them; and he stood by them under the tree while they ate.
They said to Abraham, “Where is your wife Sarah?” And he said, “There, in the tent.”
Then one said, “I will surely return to you in due season, and your wife Sarah shall have a son.”
Psalm 15
R. O Lord, who may abide in your tent?
Whoever walks blamelessly, and does what is right, and speaks the truth from their heart; whoever does not slander with their tongue. R.
Whoever does no evil to a friend, nor takes up a reproach against a neighbour; in whose eyes the wicked one is despised, but who honours those who fear the Lord. R.
Whoever stands by their oath even to their hurt; who does not lend money at interest, and does not take a bribe against the innocent. One who does these things shall never be moved. R.
Second Reading Colossians 1.24-28
Brothers and sisters: I am now rejoicing in my sufferings for your sake, and in my flesh I am completing what is lacking in Christ’s afflictions for the sake of his body, that is, the Church.
I became its servant according to God’s commission that was given to me for you, to make the word of God fully known, the mystery that has been hidden throughout the ages and generations but has now been revealed to his saints.
To them God chose to make known how great among the Gentiles are the riches of the glory of this mystery, which is Christ in you, the hope of glory. It is Christ whom we proclaim, warning every person and teaching every person in all wisdom, so that we may present every person mature in Christ.
Gospel Luke 10.38-42
Now as Jesus and his disciples went on their way, he entered a certain village, where a woman named Martha welcomed him into her home. She had a sister named Mary, who sat at the Lord’s feet and listened to what he was saying.
But Martha was distracted by her many tasks; so she came to Jesus and asked, “Lord, do you not care that my sister has left me to do all the work by myself? Tell her then to help me.”
But the Lord answered her, “Martha, Martha, you are worried and distracted by many things; there is need of only one thing. Mary has chosen the better part, which will not be taken away from her.”
