This was a pretty good talk, but I believe canon hesse is wrong when it comes to heart transplants. The position that I understand is traditional is that heart transplants are doubtful. And, they are doubtful because we cannot determine the true point of death. And, in many cases, doctors are rushing to conclusions. Because, a live heart, or one as close to living is needed for transplants. But, canon hesse doesn't talk about that. Without scruple, he appears to think it is okay. Start listening at minute 148:30.
Hesse also talks immediately after about how he agrees with Paul VI when it comes to eating already dead human flesh in emergency situations. And, I am not convinced that I would do that. I didn't hear of any "moral" cannibalism having occurred when reading about the ukrainians(many were christians) who were starved by stalin in the 1930s. They ate the flesh of trees(bark) yes, but they weren't eating the flesh of dead humans. They may not have lived on physically. But, they live on in my memory. And, many events of history are forgotten, and for good reason. But, I won't be forgetting about them.
