Washing of the Feet

The Last Supper is the final meal that Jesus shared with his apostles in Jerusalem before his crucifixion and provides the scriptural basis for the Eucharist.
Later this became a retelling of the events of the last meal, and a ritual which recounted that meal. What is forgotten is that after the meal......
He rose from Supper, laid aside his garments, took a towel and girded himself. He then poured water in a basin and began to wash his disciples feet 

Jesus then instructs his disciples,"If I then your Lord and Teacher have washed your Feet, you also have to wash one another's feet. (John 13: 14-17)

After that he wore his garment and was seated, as he said unto them," Know ye what I have done to you.Ye call me Master and Lord: and yes 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.
The entire emphasis that night was on serving one another as commanded: "Love one another, as I have Loved you."

The Mass today dwells only on the Supper and the bigger question posed before us is, have we relegated washing of the feet to a once a year ritual.
