There isn’t an official set of Baptist theological beliefs. Baptist churches are autonomous and have a variety of different beliefs - the varieties of Calvinism and Arminianism would be two big ones among others.
Just to ease your mind, in all my time as a Baptist I only remember the Word of God ever being preached, not Calvinism or Arminianism as neither is biblical doctrine. When Baptists of different churches come together, every single one will bring a bible, trust me, and will be checking it diligently to see if what the speaker says is true.
As to "different beliefs" you are going to have to come up with something better than that.
