First Reading: First Thessalonians 4: 1-8
1 For the rest therefore, brethren, we pray and beseech you in the Lord Jesus, that as you have received from us, how you ought to walk, and to please God, so also you would walk, that you may abound the more.
2 For you know what precepts I have given to you by the Lord Jesus.
3 For this is the will of God, your sanctification; that you should abstain from fornication;
4 That every one of you should know how to possess his vessel in sanctification and honour:
5 Not in the passion of lust, like the Gentiles that know not God:
6 And that no man overreach, nor circumvent his brother in business: because the Lord is the avenger of all these things, as we have told you before, and have testified.
7 For God hath not called us unto uncleanness, but unto sanctification.
8 Therefore, he that despiseth these things, despiseth not man, but God, who also hath given his holy Spirit in us.
Responsorial Psalm: Psalms 97: 1 and 2b, 5-6, 10, 11-12
1 For the same David, when his land was restored again to him. The Lord hath reigned, let the earth rejoice: let many islands be glad.
2 Clouds and darkness are round about him: justice and judgment are the establishment of his throne.
5 The mountains melted like wax, at the presence of the Lord: at the presence of the Lord of all the earth.
6 The heavens declared his justice: and all people saw his glory.
10 You that love the Lord, hate evil: the Lord preserveth the souls of his saints, he will deliver them out of the hand of the sinner.
11 Light is risen to the just, and joy to the right of heart.
12 Rejoice, ye just, in the Lord: and give praise to the remembrance of his holiness.
Gospel: Matthew 25: 1-13
1 Then shall the kingdom of heaven be like to ten virgins, who taking their lamps went out to meet the bridegroom and the bride.
2 And five of them were foolish, and five wise.
3 But the five foolish, having taken their lamps, did not take oil with them:
4 But the wise took oil in their vessels with the lamps.
5 And the bridegroom tarrying, they all slumbered and slept.
6 And at midnight there was a cry made: Behold the bridegroom cometh, go ye forth to meet him.
7 Then all those virgins arose and trimmed their lamps.
8 And the foolish said to the wise: Give us of your oil, for our lamps are gone out.
9 The wise answered, saying: Lest perhaps there be not enough for us and for you, go ye rather to them that sell, and buy for yourselves.
10 Now whilst they went to buy, the bridegroom came: and they that were ready, went in with him to the marriage, and the door was shut.
11 But at last come also the other virgins, saying: Lord, Lord, open to us.
12 But he answering said: Amen I say to you, I know you not.
13 Watch ye therefore, because you know not the day nor the hour.
