Don't you mean the Comander in Chief, Saint Michael?I understood the Archangel Gabriel is God's messenger, and does fight under Saint Michael's leadership, but is not the Supreme Commander.*
In the old calendar March 24 is observed as the feast of St. Gabriel. I used a prayer from the Byzantine liturgy for St. Gabriel.In the new calendar the 3 archangels are commemorated together on September 29.
Gabriel was my confirmation name when I was confirmed into the Catholic Church thru RCIA...I chose his name as I am an engineer by trade, primarily in communications circuits. He has aided me greatly..Sara (yes this is my real name)
