'Quality' in the Bible

by abolishing in His [own crucified] flesh the hostility caused by the Law with its commandments contained in ordinances [which He satisfied]; so that in Himself He might make the two into one new man, thereby establishing peace.

And have no company with the works of the dark, which give no fruit, but make their true quality clear;

But all things, when their true quality is seen, are made clear by the light: because everything which is made clear is light.
