Branch theory: A Cursory Defense

 One YouTuber I've recently run across and really profited from/enjoyed is Jonah Saller at the Mere Catholicity channel.  I believe that Mr. Saller is an Anglican layman and has lots of really thoughtful videos advocating for a "reformed catholicity".  Here he discusses the view held by many (but not all) Anglicans called "Branch theory" - the idea that the original undivided and catholic church founded by Christ has divided into (at least) three branches that can all claim to be legitimately "catholic" continuations of that original "trunk" with the same validity of ordinations and sacraments: the Eastern Orthodox, the Roman Catholic, and the Anglican branches.  While some Anglicans use "Branch Theory" to "de-church" other Protestant churches, Mr. Saller - in this an other videos - takes a more generous (and, I would argue, a more realistic) approach: other Protestant churches are clearly real parts of Christ's church that really experience the saving grace of Jesus Christ; but there are gifts of catholicity (such as Apostolic bishops) that God intends for them to have, which they currently lack.
