You, son of man — I have appointed you as a sentinel for the house of Israel; when you hear a word from my mouth, you must warn them for me.
When I say to the wicked, "You wicked, you must die," and you do not speak up to warn the wicked about their ways, they shall die in their sins, but I will hold you responsible for their blood.
If, however, you warn the wicked to turn from their ways, but they do not, then they shall die in their sins, but you shall save your life.
This passage came to mind in thinking about how fruitless is all the kvetching I see about heterodox Catholics.
More than fruitless, though, it suggests the kvetching might be actively dangerous. A sentinel who does not speak up to warn the wicked about their ways will be held responsible for their blood. Will a sentinel who speaks up in a way morally certain to gratuitously offend the wicked get off any easier?
