He was girded. For I have given you an example, that ye should do as I have done to you. Baptism is a ceremony. The Lord's Supper is a ceremony. The Washing of the Saints' Feet is a ceremony.
Baptism makes use of water, enough water in which to be buried.
The Lord's Supper makes use of bread and wine. The washing of the Saints' Feet makes use of the basin of water and the towel. These elements all represent spiritual truths, as we shall see. The Washing of the Saints' Feet represents the willing humiliation of Christ. Our Lord left the glory of Heaven to come to earth and live among men as a man.
