Whereupon, O king Agrippa, I was not incredulous to the heavenly vision: But to them first that are at Damascus, and at Jerusalem, and unto all the country of Judea, and to the Gentiles did I preach, that they should do penance, and turn to God, doing works worthy of penance. For this cause the Jews, when I was in the temple, having apprehended me, went about to kill me. But being aided by the help of God, I stand unto this day, witnessing both to small and great, saying no other thing than those which the prophets, and Moses did say should come to pass: That Christ should suffer, and that he should be the first that should rise from the dead, and should shew light to the people, and to the Gentiles.

Gospel Reading: John 10:11-16
I am the good shepherd. The good shepherd giveth his life for his sheep. But the hireling, and he that is not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and flieth: and the wolf catcheth, and scattereth the sheep: And the hireling flieth, because he is a hireling: and he hath no care for the sheep. I am the good shepherd; and I know mine, and mine know me. As the Father knoweth me, and I know the Father: and I lay down my life for my sheep. And other sheep I have, that are not of this fold: them also I must bring, and they shall hear my voice, and there shall be one fold and one shepherd.
