What is the meaning of humanity? As defined by Wikipedia
Humanity differs from mere justice in that there is a level of altruism towards individuals included in humanity more so than the fairness found in justice. That is, humanity, and the acts of love, altruism, and social intelligence are typically person to person strengths while fairness is generally expanded to all.
As a Christian, one of my favorite passages about humanity is James.
Love your neighbor as yourself
I would like to close with these words from Robert Kennedy
