DO THIS IN MEMORY OF ME.
"Was ever another command so obeyed? For century after century, spreading slowly to every continent and country and among every race on earth, this action has been done in every conceivable human circumstance for every conceivable human need, from infancy and before it, to extreme old age and after it, . . . and best of all, week by week, and month by month, on a hundred thousand Sundays, faithfully, unfailingly, across all the parishes of Christendom, priest and people continue to work together in order to carry out this command, "Do this in memory of me." — Don Gregory Dix
