Purity, Impurity, and the Modern World: Thoughts for Parashat Hukat, June 15, 2013
In ancient times, one who came into contact with the dead body of a human being was considered to be ritually impure and needed to undergo a purification process involving the ashes of a red heifer. It should be remembered that it is a mitzvah to care for a dead body and to participate in a proper funeral and burial. Thus, becoming ritually impure was a “normal” fact of life which occurred to almost everyone.
