Patterson doesn't own the SBC, much as he might like to. It's a big denomination with many different, sometimes rival power centers. And at 74, he's hardly the future of the SBC.
Some men should quit while they're ahead. Marshal Pétain went from being a war hero in WWI to a Nazi collaborator in WWII. Died in disgrace.
Patterson did some yeoman work during the inerrancy wars back in the 70s, but he had a taste for power. His frequent abuse of authority and mismanagement of SWBTS has sullied his former reputation.
He's like those revolutionaries who had a good cause, but having toppled a bad regime, replaced it with their own bad regime. A certain Cuban dictator, recently deceased, comes to mind.
The Trojan horse comparison is inept. In that ruse, the Greeks were hiding inside the wooden horse to stage a takeover. By contrast, Calvinists in the SBC are out in the open.
