Isaiah 6:1-8 New Revised Standard Version (NRSV)
1 In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lofty; and the hem of his robe filled the temple. 2 Seraphs were in attendance above him; each had six wings: with two they covered their faces, and with two they covered their feet, and with two they flew. 3 And one called to another and said:
“Holy, holy, holy is the Lord of hosts;
the whole earth is full of his glory.”
4 The pivots on the thresholds shook at the voices of those who called, and the house filled with smoke. 5 And I said: “Woe is me! I am lost, for I am a man of unclean lips, and I live among a people of unclean lips; yet my eyes have seen the King, the Lord of hosts!”
6 Then one of the seraphs flew to me, holding a live coal that had been taken from the altar with a pair of tongs. 7 The seraph touched my mouth with it and said: “Now that this has touched your lips, your guilt has departed and your sin is blotted out.” 8 Then I heard the voice of the Lord saying, “Whom shall I send, and who will go for us?” And I said, “Here am I; send me!”
Ephesians 6:10-11, 18-20
10 Finally, be strong in the Lord and in the strength of his power. 11 Put on the whole armor of God, so that you may be able to stand against the wiles of the devil.
18 Pray in the Spirit at all times in every prayer and supplication. To that end keep alert and always persevere in supplication for all the saints. 19 Pray also for me, so that when I speak, a message may be given to me to make known with boldness the mystery of the gospel, 20 for which I am an ambassador in chains. Pray that I may declare it boldly, as I must speak.
Gospel reading
John 21:15-17
15 When they had finished breakfast, Jesus said to Simon Peter, “Simon son of John, do you love me more than these?” He said to him, “Yes, Lord; you know that I love you.” Jesus said to him, “Feed my lambs.” 16 A second time he said to him, “Simon son of John, do you love me?” He said to him, “Yes, Lord; you know that I love you.” Jesus said to him, “Tend my sheep.” 17 He said to him the third time, “Simon son of John, do you love me?” Peter felt hurt because he said to him the third time, “Do you love me?” And he said to him, “Lord, you know everything; you know that I love you.” Jesus said to him, “Feed my sheep.”
