First Reading Galatians 1:13-24

13For you have heard of my former life in Judaism, how I persecuted the church of God violently and tried to destroy it; 14and I advanced in Judaism beyond many of my own age among my people, so extremely zealous was I for the traditions of my fathers. 15But when he who had set me apart before I was born, and had called me through his grace, 16was pleased to reveal his Son to me, in order that I might preach him among the Gentiles, I did not confer with flesh and blood, 17nor did I go up to Jerusalem to those who were apostles before me, but I went away into Arabia; and again I returned to Damascus. 18Then after three years I went up to Jerusalem to visit Cephas, and remained with him fifteen days. 19But I saw none of the other apostles except James the Lord's brother. 20(In what I am writing to you, before God, I do not lie!) 21Then I went into the regions of Syria and Cili'cia. 22And I was still not known by sight to the churches of Christ in Judea; 23they only heard it said, "He who once persecuted us is now preaching the faith he once tried to destroy." 24And they glorified God because of me.

Responsorial Psalm Psalms 139:1-3, 13-15

1O LORD, thou hast searched me and known me! 2Thou knowest when I sit down and when I rise up; thou discernest my thoughts from afar. 3Thou searchest out my path and my lying down, and art acquainted with all my ways. 13For thou didst form my inward parts, thou didst knit me together in my mother's womb. 14I praise thee, for thou art fearful and wonderful. Wonderful are thy works! Thou knowest me right well; 15my frame was not hidden from thee, when I was being made in secret, intricately wrought in the depths of the earth.

Gospel Luke 10:38-42

38Now as they went on their way, he entered a village; and a woman named Martha received him into her house. 39And she had a sister called Mary, who sat at the Lord's feet and listened to his teaching. 40But Martha was distracted with much serving; and she went to him and said, "Lord, do you not care that my sister has left me to serve alone? Tell her then to help me." 41But the Lord answered her, "Martha, Martha, you are anxious and troubled about many things; 42one thing is needful. Mary has chosen the good portion, which shall not be taken away from her."
