i am not interested in it being a command - but if a person is so closed mind about it, they can miss out on a blessing . but this day and age foot washing is pretty much out the door
One of the reason that it may not be popular is that the Roman Catholic Church on Maundy Thursday of Holy Week. The Protestant church does not want to be seen doing anything that the Catholic church does.
Another thought is that washing feet in those days was an act of hospitality or personal hygiene.
When the Scriptures are studied that is the pattern seen in each of of those Scriptures. This makes sense in that land where people often traveled by foot, wearing sandals, walking in hot, dusty sand. Washing the feet was done to comfort guests, meet their needs, and welcome them. When one person did it for others, it was considered a menial task of service.
It was not a ritual done as an act of worship. People had a physical need, just like they might need food or a place to spend the night. Hospitality involved providing whatever would meet that need.
It also follows that there was no purpose in washing the feet of those whose feet were clean. Such people would not need their feet washed.
Personally I think it would be helpful to remember that in none of the Bible cases was washing of feet a worship ritual done in the context of worship meetings.
It was an individual act done as an act of hospitality to visitors.
Just a thought!
