Q. 1. What is the "virtue of Justice?"
A. 1. In summary, the virtue of justice allows us to give God and our neighbor their due, thus safeguarding the rights of God and others.
According to # 1807 of the Catechism of the Catholic Church, the virtue of "Justice is the moral virtue that consists in the constant and firm will to give their due to God and neighbor. Justice toward God is called the "virtue of religion." Justice toward men disposes one to respect the rights of each and to establish in human relationships the harmony that promotes equity with regard to persons and to the common good. The just man, often mentioned in the Sacred Scriptures, is distinguished by habitual right thinking and the uprightness of his conduct toward his neighbor. "You shall not be partial to the poor or defer to the great, but in righteousness shall you judge your neighbor." "Masters, treat your slaves justly and fairly, knowing that you also have a Master in heaven."
According to the Holy Bible on the subject of justice, "Jesus said to them, “Then give back to Caesar what is Caesar’s, and to God what is God’s.” [Lk.20:25]
