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.

In the year King Uzziah died, I saw the Lord seated on a high and lofty throne, with the train of his garment filling the temple. Seraphim were stationed above; each of them had six wings: with two they veiled their faces, with two they veiled their feet, and with two they hovered aloft. They cried one to the other, “Holy, holy, holy is the LORD of hosts! All the earth is filled with his glory!” At the sound of that cry, the frame of the door shook and the house was filled with smoke. (Is 6:1-6)

The Call of the Prophet Isaiah begins with this vision of the Lord and the seraphim. The song of the seraphim is echoed in the Sanctus (Holy, Holy, Holy) of the Eucharist. In one sense the liturgy on earth unites with the liturgy of heaven in one chorus of endless praise.
