(a) In John 13:14, Jesus says, “You should wash one another’s feet.” Most Christian groups do not have a foot-washing liturgy. Why not? In what ways can we fulfil this command even if we do not follow it literally?

(b) In Luke 22:19, Jesus says, in connection with the Last Supper, “Do this in remembrance of me.” Most Christian groups do have a ‘Lord’s Supper’ liturgy. Why? Looking at this passage in Luke, what would you say are the main things about Jesus that we are to ‘remember’ when we take communion?
