Our God has revealed the greatness of man. The fact that Christ became human was, is, and will forever remain a sign that man is so vast, so mysteriously deep, that not only can he contain - as a temple - the divine presence, but he can also unite with God, become a "partaker of the divine nature," according to the apostle Peter. And yet, no matter how much man deviated from his calling, no matter how unworthy he became of it, he will never have a relationship with God inferior to that of fatherhood, and he will never cease to have the position of a son or daughter of the Most High...
What is revealed in Christ and through Christ is that what matters most is each individual person; that Christ lives and dies for each of us, that He is not interested in the masses but in each individual.
The ancient world knew nations and tribes, it knew slaves and masters, it had categories of people, just as the modern world distinguishes categories and types and groups. God knows only living human beings - men and women.
