Do the Baptists Need a Magisterium?

With Jimmy Carter's new book  about the Bible we see how his private interpretation of it gives him the right and authority to justify homosexual unions. No one in his denomination can tell him he is wrong! Why? Because he left Southern Baptists when they disagreed with his interpretation and joined another sect of baptists that allow for his interpretation.  " I’m a Baptist, and I believe that each congregation is autonomous and can govern its own affairs. So if a local Baptist church wants to accept gay members on an equal basis, which my church does by the way, then that is fine. If a church decides not to, then government laws shouldn’t require them to."    (By the way, the Catholic faith accepts "gay" members as well, they just don't condone the lifestyle or approve of homosexual unions)
   There's no arguing with former President Jimmy Carter when it comes to his interpretation of the Bible. This is how he believes God is leading him to interpret it. Once again, without a magisterium, an individual with his personal interpretation of the bible essentially becomes his own pope and magisterium. If you don't believe it, just look at the thousands of sects that all believe they each, individually have the most correct and accurate interpretation of scripture.
