The late theologian R.J.Rushdoony was a Christian reconstructionist and considered the father of the movement which is also known as Theonomy which means God’s law.
Rushdoony believed that the civil government of any given country is obligated to align its laws and accompanying penalties with the laws of God described in the Bible with particular emphasis on the Old Testament.
Thus the death penalty for sins/crimes such as murder, sodomy, adultery, kidnapping, rape and other equally abhorrent offences would be prescribed and enforced.
Such laws and penalties would certainly act as a deterrent to would-be murderers and adulterers and there would be no abortion mills and no “gay” pride parades or men dressed as women in women’s facilities.
I agree with the reconstructionists to a point. I believe murderers should be executed but whilst I believe that adultery and sodomy are capital offences and deserving of severe punishment, I would not advocate the death penalty for sodomites and adulterers. I would make sodomy and adultery illegal and I would imprison such but I would not go so far as advocating the death penalty for such
Rushdoony described adultery and sodomy as treason to the family and he is absolutely right.
However although I do not accept all the views of the reconstructionists but I believe that Christians should gravitate to some degree towards a Christian reconstruction of society for the good of all, believer and non-believer alike.
