'...part of our Christian vocation is proclaim the reality of death itself. Nothing could be more revelatory on contemporary forgetfulness - or faithfulness - than the disappearance of this proclamation from Christian teachers and preachers as a central part of the gospel they announce. The tradition of memento mori - "remember that you must die" - was not merely a medieval invention. It stands as a central scriptural focus (e.g. , Ps 39:6; Luke 12:20). For to proclaim death, at least in its central aspect of our existence, is to return always to the form of our being as creatures. To announce our creaturehood is to proclaim God.'
Ephraim Radner, A Time to Keep, p.152.
