Ancient Words Ever True...

I was listening to the song Ancient Words in the office today, considering the words of Peter in Acts 4, and pondering the book, The Reformation by Diarmaid MacCulloch.  Where did all of that lead me?  The Reformation (in conjunction with the Renaissance) was a difficult time for those who wished to respect ancient traditions.  If you wanted to revere all the wisdom of the ancients, you had to deny the observations of men like Copernicus and Galileo in favor of men dead for two thousand years like Aristotle and Ptolemy. 
If instead, you opened up the wisdom of the ancients to doubt, even ridicule, how could you hold the line and protect the Orthodox faith from those who would deny the Trinity (for example)?
For us, the answers seem easy: Copernicus was right and that doesn't say anything about Biblical interpretation, it's just an observation from the natural world.  It wasn't so simple at the time.  We, as supposedly enlightened modern thinkers, may scoff at the foolishness of our forefathers, and shake our heads that they ever burned "witches" at the stake; but the question should be, "Are we any better?"
Take a look around the world we live in.  It has become the accepted belief in the Modern West that a human embryo can be disposed of with not a bit of care, and even an ironic moral outrage at those who would seek to "force" a young girl to give birth to the child growing inside of her.  It has also become the accepted belief in much of the Modern West that any and all variations of sexuality, co-habitation, and separation are equally valid.  That nobody has the right to tell anyone else that their choices are wrong.
Does it really seem so funny that men in the 16th Century were troubled that Copernicus was claiming the earth revolved around the sun?  In reality, humanity hasn't "advanced" much at all over the last five centuries.  We may know more stuff, and have a lot more widgets and gizmoes to entertain ourselves, but our moral state is just as deprived as the day Luther became troubled with Paul's insistence on fallen humanity in his letter to the Romans.
