We're of like mind on the first point.
On the second point, the mere fact alone that teachings may be 2000 years old doesn't allow us to conclude there isn't great wisdom to be learned from those teachings. New teachings, such as Nazism, can be far more depraved than the teachings of some shaggy hair dude from Nazareth. The teachings of Confucius are well over a thousand years old, yet they seem to be a pretty decent guide to human life.
As the horrifying events of the 20th Century demonstrate, it is not necessarily the case that "the moral standards of the current society are far more advanced". We committed atrocities in the name of advanced scientific teachings -- the supremacy of the master race in the case of the Nazis and the proletariat in the case of the communists. And in the Americas, the slaughter of indigenous peoples was justified by "progress" (although most deaths came from the spread of disease, we did slaughter gobs of Native Americans). In each of those three cases -- the slaughter of the Jews, the slaughter of opponents of communism and the slaughter of indigenous peoples in the Americas -- there is no question that the true teachings of Jesus Christ condemn such barbarism. I'm afraid we cannot conclude that it
Frig. I had a nice reply typed on my laptop but it died again and sunk my post with it so I'm back on my iPad.
Briefly put, ancient wisdom can still be good wisdom. Contemporary wisdom can be wretched.
Hundreds of millions of human beings were slaughtered over the last century in the name "progress" -- nazism and communism. Had the nazis and communists embraced the true teachings of Christ or Confucius they would not have orchestrated the horrific genocides -- which we must acknowledge was perpetrated in the name of "progress" -- that they did.
Old is old, but old isn't necessarily outdated, nor is the new always more "advanced" than the old.
I'm sorry, but I have to disagree with you completely. Here are my objections:
1. You are identifying "contemporary wisdom" with examples like Nazism and Communism, completely ignoring that after 12 year run, Nazism has been overthrown by the same "contemporary wisdom" and Communism after several decades is also largely overthrown. This is the beauty of a secular society - it recognizes that some ideas are wrong and discards them; religious society on the other hand insists that the ideas that were good 2000 years ago should still be good and refuses to change and evolve.
2. You are completely forgetting that the "ancient wisdom" as you call it is guilty of just as many if not more atrocities. The difference again is that religion is incapable to change from within - it takes enormous pressure for a prolonged period of time before it even acknowledges that there is a problem. For example child molestation by priests has been going on for centuries and it has been always swept under the carpet by the church. Under a lot of pressure by the society the pope issued an apology for a first time in 2014, but still no actions taken to make sure it doesn't happen in the future. The church's way of dealing with it was to suppress the news and move the priest to a different parish, where he could continue to do the same things. I can go on with many more examples - the inquisition's persecution of heretics, the witch burnings, the sharia law executions...
3. You are saying that Nazism is a "new teaching" and has nothing to do with religion. The truth is very different - the Nazis used religion extensively to gain support for their movement. It's true that Hitler persecuted some religions, most notably the Jews, but Christianity was a very important for him. The catholic church was working hand in hand with the fascist regimes around Europe at that time, so the first thing he did when he came into power was to reach a treaty with the Vatican, which legitimized his power. Here is a quote from Hitler from 1933:
I have been attacked because of my handling of the Jewish question. The Catholic Church considered the Jews pestilent for fifteen hundred years, put them in ghettos, etc., because it recognized the Jews for what they were. In the epoch of liberalism the danger was no longer recognized. I am moving back toward the time in which a fifteen-hundred-year-long tradition was implemented. I do not set race over religion, but I recognize the representatives of this race as pestilent for the state and for the Church, and perhaps I am thereby doing Christianity a great service by pushing them out of schools and public functions.
Also immediately after annexing Austria in 1938 he ordered SS to seize the Spear of Destiny - a catholic relic that is claimed to be used by a Roman soldier to pierce the side of Jesus on the crucifix. He claimed that whoever is in possession of the Spear of Destiny is invincible. He displayed it at the cathedral of Nuremberg and later kept it in a specially constructed bunker underneath.
As you can see Nazism used a lot of the so called "ancient wisdom". I suggest you read about the catholic church and it's connections with Fascism and Nazism. There are a lot more unflattering things you will find out. In 1998 the pope apologized for it.
4. You are claiming that in the Americas, the slaughter of indigenous peoples was justified by "progress" and has nothing to do with religion - this claim is so ridiculous, that I'm starting to think that you are on a WUM. Conversion of the local population to Christianity was one of the main goals of the conquistadors along with the search for gold and claiming the land for the crown. In 1965 the pope apologized for it.
5. Communism - this is probably the only bad thing you quoted, that has very little to do with religion, except for North Korea, which flavor of communism is a modified version of the traditional Korean ancestral worship religion, with Kim Jong-il proclaimed as the Eternal General Secretary after his death.
There is some common pattern here - the church does nothing when is required and sometimes centuries later the pope halfheartedly apologizes - that's how religion works.
