Fr. Gabriel Rochelle teaches that the Zacchaeus' story is a great demonstration of the truth that being Christian is not about being good. Zacchaeus' ethic is above reproach, but this shows us that ethics is not what the faith is about. It is about having Christ come into your life, into your heart, and transform you from within, to renew your nature. As St Cyril of Alexandria pointed out, Zacchaeus' small stature is spiritual, not merely physical. He needs to be enlarged by Christ in the core of his life. We all do. (Luke 19:1-10)
