[Ol' Sparky]

First, executing the adultress was up to the governing authorities, not individuals. The Bible only gives the governing authority the right to excute (Romans 13:4). But, Christ most certainly upheld the Mosiac Law in regard to the death penalty for adultery. In fact, in Mark 7:8-11, Jesus upheld the Mosiac Law in regard to children cursing their parents.

The Bible only gives the governing authority the right to excute (Romans 13:4).

Not to get off on a tangent, but this is the words of Paul, not Christ. Many of the writings of Paul seem to contradict the words of Christ.

I'd be curious on your take of Paul's claim that "governments are instituted by God". I don't know where he got this from. The Soviet Union, the Taliban or the government ran by Pol Pot were not instituted by God.
