Just a quick note.
In the 19th century a number of Oxford University professors began what came to be known as the Oxford Movement. They put forth the idea that the Anglicans had their roots in the Roman Church and as such might see reunification. Some time in the 1930’s the magisterium ruled that the priestly ordinations of the Anglicans were invalid as to form, and thus ended the construct. GK Chesterton comes to mind, as perhaps the last of the line.
