Why did Jesus wash the Disciples' feet? After washing the Disciples' feet, Jesus explained what He did and why. In church, the foot washing ceremony is an important call for all people that they too should be willing to serve others. Members of the congregation are chosen to sit and have their feet washed by the priest, who plays the role of Christ. 14 If I, then, the Lord and Master, have washed your feet, you must wash each other's feet.
