Perhaps no action by Pope Francis has generated as much astonishment as his washing the feet of prisoners—men, women, Christian, Muslim. It is a return to what Jesus intended: As I have done, so you must do. The Holy Thursday liturgy is marked by the ritual gesture of the washing of the feet. The central action of service reminds us that our communion is more than a meal, more than nourishment for our bodies and souls. It’s the act of taking on the mission, the ministry, the very body of Christ. And it is a challenge to us to remain in communion with one another.
