We know Jesus did not command his disciples to literally wash one another's feet in perpetuity, as some folks would say today. The lesson he taught by this was humility, love, and service. The lesson was not about having clean feet or washing feet specifically, it is about serving one another. If we grasp the big picture, we each will do the fine tuning ourselves. The main thing to remember about our God-given responsibilities toward our parents is that we love them just as we are to love all people.
Christians are obligated support their parents financially whenever necessary.
It was there that He rebuked the Pharisees, because they had neglected to provide for their parents. Godly children will bring joy to their parents. Dan Morris Galt, Ca. Visit the Vacaville church of Christ home page.
