Jesus washed the feet of his DISCIPLES..those who believed in Him...not the Pharisees. There MUST be a clear line drawn by the church between Islam and Christianity evil and good. One does not appease those whose stated goal is destruction of all who will not sumbit. Even Jesus did not HELP those nailing him to the cross.
These people were CHOSEN..why choose an enemy of all that you are and believe?
You didn’t answer the question. Do you think, had Christ been washing feet, and this young woman was before her, he would have denied her? Skipped her? Called her an apostate and moved on? Rained down fire and brimstone upon her? What do you think he would have done?
Jesus performed many miracles for non-believers. He used the miracles to demonstrate he was filled with the spirit of God. He did not determine if they were believers beforehand.
And, if the ultimate goal is to convert this young woman to Christianity, don’t you think washing her feet and showing the compassion of Christ would be more effective that ignoring or castigating her?
