text: I believe that it is a mortal sin to commit adultery, a further mortal sin to receive Communion in a state of mortal sin; most Catholics are aware of this. Mortal sin deprives the soul of sanctifying grace.
  I can't stop anyone divorcing and remarrying outside the Church nor can I stop them going to Communion; all I can do is advise them of the eternal consequences of their actions. In the end what they do is their decision. Cain's response, "am I my brother's keeper?" have been held against him throughout history.
  Are you saying that we should not care for the spiritual welfare of our fellows as well as their material needs?
