Reformed Baptist, you are correct, my question about your name has no relevance, I am just curious and wished to understand you better on the need to be "reformed". I've heard the phrase before concerning various churches, just never really understood. Thank you for answering me. If you would care to expand more on this, I would gladly listen.
As far as the "need" to wash feet, again you are correct that we no longer walk for miles barefoot, or in sandals on dry, dusty roads. I think Jesus took the common practice of that day to use as a teaching moment when others thought themselves too highly to stoop down and wash another's feet. He did as an example and witness to them adding that He did not come to be served, but to serve. Here, He left this witness to us as to how we should be in all things; willing to humbly serve.
As you stated; "It's about humility and there are plenty of relevant ways to learn that lesson today, and practice what we learn without creating some ritual to practice." This was my exact reasoning in using the example of kneeling in prayer, or washing dishes for my neighbor. I suppose washing dishes is a good example for me since this is something I do not enjoy doing. Kneeling in prayer is also something we do not often see done, even in our churches, unless you happen to be Catholic, never-the-less it denotes humility.
Personally, I would like to see more people kneel in prayer, as I would like to see someone humble themselves, come to my house, and wash my dishes. I believe, though, that kneeling in prayer may be of more self edification than washing my dirty dishes. I find merit in both.
As for walking on water, well Jesus did allow Peter to also walk on the water, but for me this lesson is about keeping our eyes focused on Jesus, never doubting Him and exercising our faith to follow whatever it is that He might ask us to do, even have a good old-fashioned foot washing.
Peace to you!
Yours in Christ Jesus,
