And Jesus said unto him,
Why call me good? there is none good but one, that is, God.
All Commentaries on Mark 10:18 Go To Mark 10
Augustine of Hippo
AD 430
God, therefore, is uniquely good, and this he cannot lose. He is good. He is not good by sharing in any other good, because the good by which he is good is himself. But, when a finite human being is good, his goodness derives from God, because he cannot be his own good. All who become good do so through his Spirit. Our nature has been created to attain to him through acts of its own will. If we are to become good, it is important for us to receive and hold what he gives, who is good in himself. Letter , To Macedonius.
