Israel loved Joseph best of all his sons, for he was the child of his old age; and he had made him a long tunic. When his brothers saw that their father loved him best of all his sons, they hated him so much that they would not even greet him. (Gen 37:3-4, 12-13a, 17b-28a)

Sibling rivalry and family squabbles are common, not very pretty occurrences in everyday life. But God can use even our basest instincts to bring about the great plan of Salvation.
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.
