So after he had washed their feet, and had taken his garments, and was set down again, he said unto them, Know ye what I have done to you? Ye call me Master and Lord: and ye say well; for so I am. If I then, your Lord and Master, have washed your feet; ye also ought to wash one another’s feet. For I have given you an example, that ye should do as I have done to you. Verily, verily, I say unto you, The servant is not greater than his lord; neither he that is sent greater than he that sent him. If ye know these things, happy are ye if ye do them. (John 13:12-17, KJV)
“Whenever this ordinance is rightly celebrated, the children of God are brought into a holy relation-ship, to help and bless each other. They covenant that the life shall be given to unselfish ministry. And this, not only for one another. Their field of labor is as wide as their Master’s was. The world is full of those who need our ministry.” (Counsels for the Church, p. 301.1)
