Modernist Bishops, including the Pope, seem to forget the entire point of the foot washing was the first Bishops learning that they should lead by example, amongst each other. The ceremony is supposed to be done between Bishops, because every single man present at the last supper betting his feet washed was a Bishop. Its not supposed to be a pharisaic self-aggrandizing through false humility ritual, its supposed to remind the Shepherds that their duty is to get their hands dirty instead of sitting back and letting the faithful be devoured by (((wolves))). Having the faithful wash each other's feet or washing the feet of random non-Christians is completely missing the point of the Ritual.
