Definition of the concept of virtue

Greetings to the Honorable Rabbi,
Regarding the concept of "with a segula" in the second book of the Trinitarians, three questions are asked (p. 405):
1. How do you define a material difference?
2. How do you empirically prove that it exists?
3. What is the source?
Answers to the Rabbi:

1. First, this is a collective matter. A fundamental difference between the "Jewish people" and Gentiles. Not between a "Jewish individual" and a "Gentile individual" (the Rabbi also noted this on page 411).
From here, we can define the difference – the Jews hold the absolute truth and lead the world there.
I bet the rabbi also agrees with this as a fact, and there is no reason he wouldn't agree that we define the essential difference as such.

An analogy for clarification:
Team leader vs. team. The essential difference is that the team leader is designed to lead the entire team to the mission ("the truth").
The Jews are the "team commander of the world."
 
2. There is no lack of evidence:
A. The Bible (the Book of Books) and its influence on the world.
on. The survival of the Jewish people over thousands of years in countless different cells, with no dependence between those cells.
third. prophecy.
D. The wisdom of the Jews.
E. Relatively high percentages of faith among the people.
F. Influence on faith in the world, including the creation of two distinct imitations (Christianity and Islam).
G. Hatred of nations.
I think anyone who honestly reads the evidence can certainly conclude that there is proof here for the definition written above.
 
3. The source: Torah verses. As the rabbi writes (page 409). Indeed, the plain meaning of the verses shows that the virtue is a state acquired by belonging to the Jewish people and observing the Torah and commandments (a fact that everyone who converts becomes part of that virtue), and not an innate "genetic load."
 
In conclusion, after it was clarified that this was a collective + what that essence was defined + we seriously judged the evidence + we found a source, we answered all of the Rabbi's questions (which between the lines the Rabbi also answered himself, only he was missing the definition that I added in the first answer).
 
I hope that now the Rabbi can rest assured regarding the concept of "a people of virtue."
*By the way, of course I'm not innovating anything, you can see a million answers from rabbis on Google that are exactly like my answer.
