In terms of the Catholic Church’s reading of Natural Law, suicide, like abortion, is a form of murder. Both are therefore forbidden by the Sixth Commandment. Suicide was once a criminal act everywhere in Christendom; not only was the attempt punishable as attempted murder, but successful suicide brought with it not only denial of Christian burial but forfeiture of estate.
So if the Catholic prohibition on abortion makes it incumbent on every Catholic voter and official to support writing that prohibition into secular law, why isn’t the same true of the Catholic prohibition on suicide?
[If some learned reader knows the actual, official answer to this question, I’d be glad to post it.]
