1 CORINTHIANS 1:26-31

26For consider your call, brethren; not many of you were wise according to worldly standards, not many were powerful, not many were of noble birth; 27but God chose what is foolish in the world to shame the wise, God chose what is weak in the world to shame the strong, 28God chose what is low and despised in the world, even things that are not, to bring to nothing things that are, 29so that no human being might boast in the presence of God. 30He is the source of your life in Christ Jesus, whom God made our wisdom, our righteousness and sanctification and redemption; 31therefore, as it is written, "Let him who boasts, boast of the Lord."

Responsorial Psalm
PSALMS 31:3-4, 6, 8, 16, 17

2Incline thy ear to me, rescue me speedily! Be thou a rock of refuge for me, a strong fortress to save me! 3Yea, thou art my rock and my fortress; for thy name's sake lead me and guide me, 5Into thy hand I commit my spirit; thou hast redeemed me, O LORD, faithful God. 7I will rejoice and be glad for thy steadfast love, because thou hast seen my affliction, thou hast taken heed of my adversities, 15My times are in thy hand; deliver me from the hand of my enemies and persecutors! 16Let thy face shine on thy servant; save me in thy steadfast love!

Gospel
LUKE 9:23-26

23And he said to all, "If any man would come after me, let him deny himself and take up his cross daily and follow me. 24For whoever would save his life will lose it; and whoever loses his life for my sake, he will save it. 25For what does it profit a man if he gains the whole world and loses or forfeits himself? 26For whoever is ashamed of me and of my words, of him will the Son of man be ashamed when he comes in his glory and the glory of the Father and of the holy angels.
