All my sources are referenced. Are you suggesting that John Adams was not a Unitarist who denied the Holy Trinity and the divinity of Christ? If so, please provide evidence.
As far as I'm aware, there is no such evidence; that is, to support your claim as stated. Anyhoot, it's your claim — i.e., that John Adams was a Unitarist who denied the Holy Trinity and the divinity of Christ. So YOU get to provide the evidence to defend it. And I am all ears.
