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.

The disciples were not educated nor were they the powerful, but they were recognizable as companions of Jesus. Perhaps that is the only qualification necessary.
