1. I've not got time to read this fully....church in about an hour and a half....but I will have trouble with the penchant to excise the story of the "woman taken in adultery" from the bible. The story sounds thoroughly Jesus-like to me and the author glossed over Augustine's and Jerome's acceptance of the incident.
2. While the death penalty in the Old Testament was permitted in a number of instances, it was not absolutely required; e.g., Bathsheba was not put to death for adultery, and David was not put to death for murder. (In fact, Joseph did not condemn Mary to death, which was the law, and he was called a "just man" for that act.)
Mercy is allowed.
If Christ was against the death penalty, why didn't He stop His?
Far from glossing over the incident, Mr. Bailey points out the incident was known to Augustine and was included in Jeromes Vulgate. The point was one of authorship, which also tied into authority given it appears to be a later insertion (after canonization), thus, it may not be regarded as scripture. Mercy is not allowed in the case of punishing a murderer (Deut. 19:13).
Actually, it WAS required for capital sin (murder).
Vis. Gen 9:6 (if memory serves) "If a man sheds another man's blood, by MAN shall his blood be shed."
God is giving Noah's descendents the rules that they are to follow in the governing of their society. In effect, God says that if you don't have capital punishment, you don't have a valid nation.
