Archbishop Denis James Hart - That will be one big millstone around your neck, do you think you can swim with it?

But he that shall scandalize one of these little ones that believe in me, it were better for him that a millstone should be hanged about his neck, and that he should be drowned in the depth of the sea. Matthew 18:6

If, when I say to the wicked, Thou shalt surely die: thou declare it not to him, nor speak to him, that he may be converted from his wicked way, and live: the same wicked man shall die in his iniquity, but I will require his blood at thy hand. Ezechiel 3:18

Seems pretty clear.
