First Reading
2 JOHN 4-9

4I rejoiced greatly to find some of your children following the truth, just as we have been commanded by the Father. 5And now I beg you, lady, not as though I were writing you a new commandment, but the one we have had from the beginning, that we love one another. 6And this is love, that we follow his commandments; this is the commandment, as you have heard from the beginning, that you follow love. 7For many deceivers have gone out into the world, men who will not acknowledge the coming of Jesus Christ in the flesh; such a one is the deceiver and the antichrist. 8Look to yourselves, that you may not lose what you have worked for, but may win a full reward. 9Any one who goes ahead and does not abide in the doctrine of Christ does not have God; he who abides in the doctrine has both the Father and the Son.

Responsorial Psalm

1Blessed are those whose way is blameless, who walk in the law of the LORD! 2Blessed are those who keep his testimonies, who seek him with their whole heart, 10With my whole heart I seek thee; let me not wander from thy commandments! 11I have laid up thy word in my heart, that I might not sin against thee. 17Deal bountifully with thy servant, that I may live and observe thy word. 18Open my eyes, that I may behold wondrous things out of thy law.

Gospel
LUKE 17:26-37

26As it was in the days of Noah, so will it be in the days of the Son of man. 27They ate, they drank, they married, they were given in marriage, until the day when Noah entered the ark, and the flood came and destroyed them all. 28Likewise as it was in the days of Lot -- they ate, they drank, they bought, they sold, they planted, they built, 29but on the day when Lot went out from Sodom fire and sulphur rained from heaven and destroyed them all -- 30so will it be on the day when the Son of man is revealed. 31On that day, let him who is on the housetop, with his goods in the house, not come down to take them away; and likewise let him who is in the field not turn back. 32Remember Lot's wife. 33Whoever seeks to gain his life will lose it, but whoever loses his life will preserve it. 34I tell you, in that night there will be two in one bed; one will be taken and the other left. 35There will be two women grinding together; one will be taken and the other left." 37And they said to him, "Where, Lord?" He said to them, "Where the body is, there the eagles will be gathered together."
