There are no absolute universal imperatives. . . .
Once again, that is an irrational, inherently self-contradictory statement. You're a slow learner, aren't you?
. . . or else we'd be stuck living in ancient times. There are imperatives that change over time, such as human sacrifice going from acceptable (and actually, considered necessity to satisfy the "Gods," ironically) to repugnant.....
burning people at the stake going from acceptable, to repugnant....
disallowing minorities and women voting right from acceptible, to repugnant
hitting your kids
teachers hitting your kids (mostly was the Religious ones, ironically)
public lynchings
segregation
You're babbling cultural relativism, shifting cultural norms or mores. Such things have nothing to do with absolute, universal imperatives. You don't even comprehend the categorical distinction between the two. The latter entails to an established philosophical/theological construct. The whole point to the assertion that ultimate truth and morality are grounded in an absolute, immutable and universal imperative is that shifting cultural norms and mores do not necessarily reflect the same, that the former is the means by which we understand the utility or the validity of the latter!
In any event, not all of your complaints are even valid. Spanking children is necessarily wrong or evil? Segregation is necessarily wrong or evil? The imposition of the loss of life or limb as a punishment for criminality is necessarily wrong or evil? Really?
where were the universal imperatives, then?
Apparently, they're in your head given your insinuation that these things are in fact bad or wrong or evil despite the fact that at one time or another, in one place or another, they were thought to be acceptable. What is the basis for your assertion now? It cannot be mere human intelligence. Intelligent people disagree about what is morally right and wrong all the time. Ultimately, though it flies right over your head, you're merely arguing that at any given time might (or majority opinion) necessarily makes right.
Romans 13:1-2 "Let every soul be in subjection to the superior authorities, for there is no authority except by God; the existing authorities stand placed in their relative positions by God. 2 Therefore he who opposes the authority has taken a stand against the arrangement of God; those who have taken a stand against it will receive judgment to themselves."
And the context:
For rulers are not a terror to good works, but to the evil. Wilt thou then not be afraid of the power? Do that which is good, and thou shalt have praise of the same: For he is the minister of God to thee for good. But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil. Wherefore ye must needs be subject, not only for wrath, but also for conscience sake. For this cause pay ye tribute also: for they are God's ministers, attending continually upon this very thing. Render therefore to all their dues: tribute to whom tribute is due; custom to whom custom; fear to whom fear; honour to whom honour. Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law.
In short, it is God, not the State, that ultimately dictates the terms of good and evil. Paul is not telling the followers of Christ that they may give that which belongs to God to the State or even obey the State should it demand evil from them, though they be sheep for the slaughter should they refuse to obey evil directives from the State.
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; Because that which may be known of God is manifest in them; for God hath shewed it unto them. For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse: Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools . . . Romans 1:18-22).
Other than your opinion, what is the authority for your morality, on what basis do you think to assert the shifting ruminations of your limited intelligence?
