First Reading Exodus 22.21-27
Thus says the Lord: “You shall not wrong or oppress a resident alien, for you were aliens in the land of Egypt. You shall not abuse any widow or orphan. If you do abuse them, when they cry out to me, I will surely heed their cry; my wrath will burn, and I will kill you with the sword, and your wives shall become widows and your children orphans.
“If you lend money to my people, to the poor one among you, you shall not deal with them as a creditor; you shall not exact interest from them. If you take your neighbour’s cloak in pawn, you shall restore it to that person before the sun goes down; for it may be their only clothing to use as cover; in what else shall that person sleep? And if that person cries out to me, I will listen, for I am compassionate.”
Psalm 18
R. I love you, O Lord, my strength.
I love you, O Lord, my strength. The Lord is my rock, my fortress, and my deliverer. My God, my rock in whom I take refuge, my shield, and the source of my salvation, my stronghold. R.
I call upon the Lord, who is worthy to be praised, so I shall be saved from my enemies. From his temple he heard my voice, and my cry to him reached his ears. R.
The Lord lives! Blessed be my rock, and exalted be the God of my salvation, Great triumphs he gives to his king, and shows steadfast love to his anointed. R.
Second Reading 1 Thessalonians 1.5c-10
Brothers and sisters: You know what kind of persons we proved to be among you for your sake. And you became imitators of us and of the Lord, for in spite of persecution you received the word with joy inspired by the Holy Spirit, so that you became an example to all the believers in Macedonia and in Achaia. For the word of the Lord has sounded forth from you not only in Macedonia and Achaia, but in every place your faith in God has become known, so that we have no need to speak about it. For the people of those regions report about us what kind of welcome we had among you, and how you turned to God from idols, to serve a living and true God, and to wait for his Son from heaven, whom he raised from the dead — Jesus, who rescues us from the wrath that is coming.
Gospel Matthew 22.34-40
When the Pharisees heard that Jesus had silenced the Sadducees, they gathered together, and one of them, a lawyer, asked him a question to test him. “Teacher, which commandment in the Law is the greatest?”
Jesus said to him, “‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ This is the greatest and first commandment.
“And a second is like it: ‘You shall love your neighbour as yourself.’ On these two commandments hang all the Law and the Prophets.”
