"Having loved his own who were in the world, he loved them to the end... then he poured water into a basin and began to wash the disciples’ feet... I give you a new commandment, that you love one another. Just as I have loved you, you also should love one another. By this everyone will know that you are my disciples, if you have love for one another.”
John 13:1b, 5, 34-35 NRSV
