Willem van Oranje
Puritan Board Junior
I just finished reading a stack of books on the Westminster Assembly (Mitchell, Hetherington, Barker, Gillespie, Mitchell & Struthers, Warfield, A. A. Hodge, and Reid). A couple of things stood out to me.
John Cotton (invited to the Assembly but did not make it) won over Davenport, Goodwin, and Nye to nonconformity. Non Westminster Assembly guy (and certifiable genius) John Owen came to Congregationalism by means of reading Cotton's The Keys of the Kingdom of Heaven evidently without any face-to-face conversations with anyone.
On the other hand, the process of studying church government in the company of the other Westminster divines won over a number of them to the Presbyterian cause or strengthened them in their resolve. I was struck by how many of the Divines started out only mildly Presbyterian or undecided, only to be convinced by the power of the arguments in the Assembly. Of course, if I had been forced to listen to the obstructionistic tactics of Goodwin, Bridge, Burroughs, Nye, and Simpson I might be more tempted to become a Presbyterian too.
