Then a cloud came, casting a shadow over them; from the cloud came a voice, "This is my beloved Son. Listen to him." (Mk 9:2-10)

The Transfiguration proclaims that the Law and the Prophets find their fulfillment in the beloved Son. The problem has always been one of failing to listen to him.
These reflections are a result of more than 40 years of ministry as a Roman Catholic priest. Most of these years I spent in the Diocese of Charlotte which covers Western North Carolina. Now I am retired, and live in Medellín, Colombia where I continue to serve as a priest in the Archdiocese of Medellín.
