Wanting to impart his episcopal blessing upon Bishop Brian and his ministry, Archbishop Karl Prüter sub-conditionally consecrated Bishop Brian Ernest Brown on the Feast of St. Ciaran of Clonmacnoise, September 9, 2007 at the Cathedral of the Prince of Peace in Highlandville Missouri. Bishop Prüter then turned over his ministry at the Cathedral of the Prince of Peace, “The World’s Smallest Cathedral” and the episcopal protection of Christ Catholic Church Diocese of the Prince of Peace to Bishop Brian’s care and continued episcopal oversight.
Bishop Brian promised to continue on with the ministry at the Cathedral for as long as he was able and was given the antimension which had been given to Bishop Prüter by Archbishop Zhurawetsky at his consecration. Bishop Brian also agreed to take on much of the work of St. Willibrord Press as per Bishop Prüter’s request. He was then given most all of Bishop Karl’s library and other assorted items and ultimately entrusted with the safe keeping and care of the cremated remains of Bishop Prüter and family in the columbarium at the Cathedral property.
