What you say about chazal is 100% emmes. Everything they say was Aish. But, we cannot forget what else they say... about "yeridas hadoros".
Each dor is weaker then the previous one. This is a FACT. This is why the achronim cannot take apart the rishonim etc, the amoraim cannot start up with the tannaim. Why, because they are in a different and lower place. So, we say, I was not zocheh to understand him. He was 100% perfectly correct, and I was the one that didn't understand.
In fact in the sefer Shomer Emunim, he states as we have seen in other musar seforim written by achronim. "I am not writing anything different then what chazal have written. NO chidushim,but, due to our lowly state, we are unfortunately not able to completely understand their words. So, I am writing in a way for our dor to understand.
