With the advent of a saint, the forms were showed which people should take*4. 君子 follows the teaching of Saint, becomes a role model for people should follow and demonstrates the behavior standards of people*5.
This is the ideal person who was called 君子 for Kongianity. He imitates Jesus Kong's behavioris and follows the teaching of Jesus Kong. We can describe him as a person who is like a Jesus Kong. 君子 is exactly the pattern of Kongian, in other words, it means a decent Kongian, or the ideal format of Kogian.
