I don't have too much to add, but I will say that I had the pleasure of meeting Archbishop Dmitri in the Spring of 2008. It was when I was concluding my protestant ministry, preparing to move to Orthodoxy, and his Eminence made a hierarchical visit to Holy Cross in the Greensboro, NC area.
His love of God and the parishioners was evident in all that he did during that visit. He took time to visit with my wife and me and encouraged us in our transition.
Please remember Vladyka in your prayers. May his memory be eternal!
