First Reading 1 Thessalonians 1:1-5, 8b-10

1Paul and Sylvanus and Timothy, to the church of the Thessalonians, in God the Father and the Lord Jesus Christ.
2Grace and peace to you. We give thanks to God always for all of you, keeping the memory of you in our prayers without ceasing,
3remembering your work of faith, and hardship, and charity, and enduring hope, in our Lord Jesus Christ, before God our Father.
4For we know, brothers, beloved of God, of your election.
5For our Gospel has not been among you in word alone, but also in virtue, and in the Holy Spirit, and with a great fullness, in the same manner as you know we have acted among you for your sake.
Some verses are not read.
8For from you, the Word of the Lord was spread, not only in Macedonia and in Achaia, but also in every place. Your faith, which is toward God, has advanced so much so that we do not need to speak to you about anything.
9For others are reporting among us of the kind of acceptance we had among you, and how you were converted from idols to God, to the service of the living and true God,
10and to the expectation of his Son from heaven (whom he raised up from the dead), Jesus, who has rescued us from the approaching wrath.

Gospel Matthew 23:13-22

13So then: Woe to you, scribes and Pharisees, you hypocrites! For you close the kingdom of heaven before men. For you yourselves do not enter, and those who are entering, you would not permit to enter.
Some verses are not read.
15Woe to you, scribes and Pharisees, you hypocrites! For you travel around by sea and by land, in order to make one convert. And when he has been converted, you make him twice the son of Hell that you are yourselves.
16Woe to you, blind guides, who say: ‘Whoever will have sworn by the temple, it is nothing. But whoever will have sworn by the gold of the temple is obligated.’
17You are foolish and blind! For which is greater: the gold, or the temple that sanctifies the gold?
18And you say: ‘Whoever will have sworn by the altar, it is nothing. But whoever will have sworn by the gift that is on the altar is obligated.’
19How blind you are! For which is greater: the gift, or the altar that sanctifies the gift?
20Therefore, whoever swears by the altar, swears by it, and by all that is on it.
21And whoever will have sworn by the temple, swears by it, and by him who dwells in it.
22And whoever swears by heaven, swears by the throne of God, and by him who sits upon it.

Computed by Bless from the US Lectionary cycle — confirm with your parish.

In US parishes the readings are proclaimed from the NABRE; the text shown here is the Catholic Public Domain Version.

Old Testament readings and the psalm are listed with a link to their chapter: the US Lectionary numbers some of their verses differently from the CPDV, so their text is not printed here. Psalm citations keep the Lectionary’s Hebrew numbering; the CPDV numbers the Psalms as the Vulgate does.
