1 Peter 2:4-6, 9-12

As you come to him, a living stone rejected by men but in the sight of God chosen and precious, you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ. For it stands in Scripture:

“Behold, I am laying in Zion a stone,
    a cornerstone chosen and precious,
and whoever believes in him will not be put to shame.”

But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. 10 Once you were not a people, but now you are God’s people; once you had not received mercy, but now you have received mercy.

11 Beloved, I urge you as sojourners and exiles to abstain from the passions of the flesh, which wage war against your soul. 12 Keep your conduct among the Gentiles honorable, so that when they speak against you as evildoers, they may see your good deeds and glorify God on the day of visitation.

John 13:1-20

1 Now before the Feast of the Passover, when Jesus knew that his hour had come to depart out of this world to the Father, having loved his own who were in the world, he loved them to the end. During supper, when the devil had already put it into the heart of Judas Iscariot, Simon’s son, to betray him, Jesus, knowing that the Father had given all things into his hands, and that he had come from God and was going back to God, rose from supper. He laid aside his outer garments, and taking a towel, tied it around his waist. Then he poured water into a basin and began to wash the disciples’ feet and to wipe them with the towel that was wrapped around him. He came to Simon Peter, who said to him, “Lord, do you wash my feet?” Jesus answered him, “What I am doing you do not understand now, but afterward you will understand.” Peter said to him, “You shall never wash my feet.” Jesus answered him, “If I do not wash you, you have no share with me.” Simon Peter said to him, “Lord, not my feet only but also my hands and my head!” 10 Jesus said to him, “The one who has bathed does not need to wash, except for his feet, but is completely clean. And you are clean, but not every one of you.” 11 For he knew who was to betray him; that was why he said, “Not all of you are clean.”

12 When he had washed their feet and put on his outer garments and resumed his place, he said to them, “Do you understand what I have done to you? 13 You call me Teacher and Lord, and you are right, for so I am. 14 If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. 15 For I have given you an example, that you also should do just as I have done to you. 16 Truly, truly, I say to you, a servant is not greater than his master, nor is a messenger greater than the one who sent him. 17 If you know these things, blessed are you if you do them. 18 I am not speaking of all of you; I know whom I have chosen. But the Scripture will be fulfilled, ‘He who ate my bread has lifted his heel against me.’ 19 I am telling you this now, before it takes place, that when it does take place you may believe that I am he. 20 Truly, truly, I say to you, whoever receives the one I send receives me, and whoever receives me receives the one who sent me.”
