He also taught that some people's sins are soooooo bad that even Christ's blood isn't good enough to cover them [WHAT BLASPHEMY!].

And that therefore, the super guilty people have to shed their own blood for their own sins. And that a devout Mormon is doing the person a favor by killing them. I guess that was the doctrine operating at the White What/White River--forget the exact title--the massacre on the Colorado River border area between AZ and UT in the late 1800's. Jim Jones would have loved Joseph.

Would that be Blood Atonement? Gary Gilmore wanted to be shot due to this particular Mormon teaching (his mom was a very dysfunctional Mormon). Most modern LDS do not discuss this topic much (tends to really get a less than positive reaction for some reason). Polygamists do use this as a threat according to Tapestry of Polygamy.

"He also taught that some people's sins are soooooo bad that even Christ's blood isn't good enough to cover them [WHAT BLASPHEMY!]. "

Is it also blasphemy when Christ teaches it?

Matt 12:32 ...but whosoever speaketh against the Holy Ghost, it shall NOT be aforgiven him, neither in this world, neither in the world to come.

"And that therefore, the super guilty people have to shed their own blood for their own sins. "
