He was known religiously as Mar Georgius I and by the titles Patriarch of Glastonbury, Catholicos of the West, and Sixth British Patriarch.
Newman was first made a bishop (a process known as consecration) in 1944.
He is most notable for having subsequently undergone numerous ceremonies of conditional consecration, thereby laying claim to numerous different lines or streams of historic apostolic succession, and also for having shared his own lines or streams of apostolic succession with numerous other bishops by conditionally consecrating them.
Over a ten-year period between 1945 and 1955, there were a number of ceremonies in each of which Newman and another bishop would conditionally consecrate each other to give each the other's lines or streams of succession, a practice that is sometimes described as "cross-consecration".Newman consecrated (conditionally, or otherwise), or shared cross-consecration with, at least 32 bishops.
Today, there are hundreds of bishops around the world, perhaps thousands, with a lines of succession deriving through Newman.
