False all around. The age of an idea doesn't correlate with the absolute validity of its principles but by an umbrella of other factors. For example, the power of who promotes it. An idea can survive for thousands of years and still be wrong. See flat earthers.

Do you need to rediscover the wheel to build a car? No. Similarly you don't need to build your values from scratch.. you only need to read what was written and logically establish if it's applicable to you or not. As a matter of fact, this is perfectly demonstrated by your Socrates point. His students were able to leapfrog him BECAUSE they learned from him first.

Finally you can go play semantic and "who's the better Christian scholar" alone. That doesn't interest me. Though I'll say that judging by the lack of humility in your post, you have a bit more reading to do.
