The reading is from St. Paul's Letter to the Romans 2:28-29; 3:1-18

Brethren, he is not a real Jew who is one outwardly, nor is true circumcision something external and physical. He is a Jew who is one inwardly, and real circumcision is a matter of the heart, spiritual and not literal. His praise is not from men but from God. Then what advantage has the Jew? Or what is the value of circumcision? Much in every way. To begin with, the Jews are entrusted with the oracles of God. What if some were unfaithful? Does their faithlessness nullify the faithfulness of God? By no means! Let God be true though every man be false, as it is written, "That thou mayest be justified in thy words, and prevail when thou art judged." But if our wickedness serves to show the justice of God, what shall we say? That God is unjust to inflict wrath on us? (I speak in a human way.) By no means! For then how could God judge the world? But if through my falsehood God's truthfulness abounds to his glory, why am I still being condemned as a sinner? And why not do evil that good may come? - as some people slanderously charge us with saying. Their condemnation is just. What then? Are we Jews any better off? No, not at all; for we have already charged that all men, both Jews and Greeks, are under the power of sin, as it is written:

"None is righteous, no, not one; no one understands, no one seeks for God. All have turned aside, together they have gone wrong; no one does good, not even one."

"Their throat is an open grave, they use their tongues to deceive."

"The venom of asps is under their lips."

"Their mouth is full of curses and bitterness."

"Their feet are swift to shed blood, in their paths are ruin and misery, and the way of peace they do not know." 

"There is no fear of God before their eyes."
