What is Three Streams Anglicanism?

Note from Pr. Shannon: "Much more could be said about all of these things. But I wanted to provide a quick overview of the three streams approach and some of the history of Anglicanism. I'm still learning and welcome helpful engagement on these things. When I said I don't buy into Apostolic succession, I meant that I don't buy into its necessity for valid sacraments. I acknowledge that there are bishops who can trace their tactile ordination all the way back to the Apostles."
