R Scott Clark visits the role of the PCA in formative years for Acts 29 and Mars Hill--there's still a pretty live question whether or not A29 and Spanish River were a tangential "accidental" role in the history of MH

I have felt pretty alone in attempting to discuss the early Acts 29, David Nicholas, Mark Driscoll and what seemed to be a PCA connection (that last part was just not on my radar because I'm just me and only have so much energy and attention). 

I'd hazard a guess that from Driscoll's side of things his earlier influences were John MacArthur and Doug Wilson (clearly if the men served on a panel together representing a rightwing perspective on censorship and the arts in 1992 ... ). David Nicholas didn't seem to come along until a few years into the life of Mars Hill. Cosper seems to have shortchanged us by not saying just how many people he talked to who had accounts of how and why Nicholas and Driscoll parted ways within Acts 29.  What is clearer is Nicholas founded and bankrolled Acts 29 and Mark Driscoll kinda was there to take it over.
