According to the Bronze script*7, and Legends telling, the Zhou Kingdom was established by God's injunction, and corrected the corrupted policy of the Yun dynasty. Individuals served the king and contributed the conquest were called 君子 later. That meant They that 君子 did good deeds in complying with the will of God.
In one of Kongianity Bible " the Analects of Jesus kong and his Apostles", Jesus Kong said that 君子 is a role model for the decent man*8, and described it as a kind of antithetical to humble-beings, which is as bad examples.
These things: The legitimacy of the Zhou dynasty, the virtues what the poetries and the documents told, and the argument about 君子 on Kongianity were consistent with each other.

*6:Kongians regard him as the king without the throne『漢書』董仲舒伝. To became king required two things: the God's order to rule the world and the handed over the throne from previous king『孟子』万章章句上 6.
