The reading is from St. Paul's First Letter to Timothy 1:8-14

Timothy, my son, we know that the law is good, if any one uses it lawfully, understanding this, that the law is not laid down for the just but for the lawless and disobedient, for the ungodly and sinners, for the unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, immoral persons, sodomites, kidnapers, liars, perjurers, and whatever else is contrary to sound doctrine, in accordance with the glorious gospel of the blessed God with which I have been entrusted. I thank him who has given me strength for this, Christ Jesus our Lord, because he judged me faithful by appointing me to his service, though I formerly blasphemed and persecuted and insulted him; but I received mercy because I had acted ignorantly in unbelief, and the grace of our Lord overflowed for me with the faith and love that are in Christ Jesus.
