Why Did Jesus Wash His Disciples’ Feet?

Why did Jesus wash his disciples’ feet? In his homily for the Mass of the Lord’s Supper, Year B,  Father Hanly shows us how, by kneeling to wash the feet of his disciples, Jesus is saying, “I want you to know how important you are, how good you are, how you gleam with the wonder of God who creates you and loves you and cares for you and sends His only Son to kneel before you and tell you, no matter what you feel, no matter what others feel, you are a child of God, an heir of heaven, a beautiful person.”
